November 2026 Digital SAT 11B: Graph Evidence, Island Clades, and Restricted Roots

By Lawrence · Updated November 12, 2026

Form 11B asks readers and problem solvers to distinguish a result that looks plausible from one that satisfies every condition. Its leaf graph supports a tendency without claiming an exceptionless rule. Its island-history passage requires careful interpretation of dates measured backward from the present. Its radical equation produces two algebraic candidates but only one valid solution. Across these contexts, the final condition does as much work as the calculation or observation.

The six cases below cover a graph, an inference about AI-created art, a cross-text scientific argument, a circle equation, a radical equation, and a rational function. The accompanying comparisons trace concrete relationships to October 2026 and older files. Some passages retain almost identical reasoning while rearranging the choices; others reuse a study but change the graph, hypothesis, or requested measurement. That distinction determines how to use this paper productively after earlier practice.

Source coverage and how to use this file

The supplied file is labeled 2026 11B and internally labeled Practice Test 5. It has 180 PDF pages and 147 numbered question occurrences: 81 Reading and Writing and 66 Math. Each subject includes Module 1 plus both an Easier and a Harder Module 2, for six blocks with six answer-key pages. These are archive and practice-file labels, not independent verification of a particular administration or adaptive route. The displayed difficulty ratings are the source’s predicted ratings, not College Board ratings. We independently explain the six selected answers below; that review is not a certification of every supplied answer.

All page references in this analysis are PDF page numbers. For a single-route rehearsal, choose one second-module block per subject; use the alternate block later for review. The 147 count describes occurrences in the full file, not 147 distinct questions on one test sitting.

Reading and Writing: match the strength of the conclusion

The opening module combines vocabulary with several different kinds of inference. Q8, p.9, adapts Defoe’s discussion of an historian’s obligations. Its point is to identify the degree of authority behind each account, including when that authority is insufficient. An answer that bans all eyewitness material is stronger and narrower than the text. This is useful preparation for Q12, p.13, where the leaf graph shows a tendency rather than a universal condition, and Q14, p.15, where the explanation of an AI-art experiment must stay within the supplied effort heuristic.

Later questions change the mode of attention. Q16, p.17, places punctuation in a scientific context involving Craig Hogan; Q18, p.19, concerns Mathemalchemy; Q26, p.27, uses notes about Oahu’s seed-dispersal network. Do not carry the evidence-question habit of comparing plausible claims into a sentence-boundary item. In grammar, first identify the clause or noun phrase attached to the blank. In notes, identify the requested goal before deciding which scientific details deserve inclusion. The content can be unfamiliar while the grammatical or rhetorical task remains local.

The easier second module includes sumptuary laws at Q11, p.45, women-judge data at Q13, p.47, and Wendy houses at Q14, p.48. These invite different questions: what evidence supports a historical claim, what pair of changes illustrates a graph statement, and what a design response implies. Q15, p.49, compares the glossy ibis and little blue heron; the harder version returns to this family at Q15, p.82. Encountering that passage twice is a review opportunity, but a later correct response after recognition is not independent evidence of improved reading speed.

The harder module places the Grande Terre cross-text problem at Q7, p.74, before literary and scientific evidence. Q11, p.78, concerns honeybees, and Q12, p.79, concerns carbon modeling at two resolutions. The latter is not asking whether respiration varies by season; it asks whether spatial resolution changes the modeled result. At Q18, p.85, a modifier must attach to the appropriate actor. At Q27, p.94, park-related notes require another careful alignment of evidence with a stated writing goal. The recurring demand is to identify the exact relationship before evaluating an option’s attractive details.

Math: domains, units, and targets

The closing part of Math Module 1 is a compact diagnostic set. Q19, p.119, contains a radical expression; Q20, p.120, requires completing squares to find circle area; Q21, p.121, concerns the number of real roots; Q22, p.122, translates a percentage relationship between two quantities. Each can go wrong after otherwise competent arithmetic if the solver outputs the wrong target: a radius instead of area, a root instead of a parameter, or a percentage as though it were a multiplier of 1.45 rather than 14.5.

The easier module includes a rational-function intercept at Q6, p.133, the restricted radical equation at Q20, p.147, and a price change from 7 to 70 at Q21, p.148. For the last, the increase is 63 relative to the original 7, so the percentage increase is 900%, not 1,000%; the latter describes the new value as a percentage of the old. Placing the original amount in the denominator before calculating is the transferable habit.

The harder module revisits a rational-function intercept at Q11, p.165, alongside a translation at Q9, p.163, and a triangle-inequality problem at Q10, p.164. Its later questions require distinguishing algebraic candidates from valid function inputs. Q16, p.170, asks for the greatest zero of a rational expression; Q18, p.172, involves reciprocals; Q21, p.175, uses the sign of a factored cubic. Before clearing denominators, write excluded inputs. Before choosing an interval for a polynomial sign, identify how many factors are negative. The final right-triangle problem at Q22, p.176, requires the geometry to justify the ratio used.

Six worked questions with source images

A graph supports a tendency, not an absolute

R&W Module 1 Q12 · PDF p.13 · Answer: C

The hypothesis predicts that paired leaves tend to have opposite-side orientation. The graph displays opposite-side and same-side counts for three grape species. In each species, the opposite-side bar is higher. C expresses exactly that repeated within-species comparison while allowing the ratio to vary. It supports the hypothesis without claiming that every leaf pair follows the pattern.

A compares the number of same-side pairs across species, which does not establish whether opposite-side pairs predominate within a species. B compares opposite-side counts for two species but likewise omits the relevant same-side baseline. D goes too far by saying all leaf pairs have opposite-side orientation; visible same-side bars directly contradict it. The difference between more and all is not a stylistic nuance here: it separates a supported tendency from a false universal statement.

Read the legend before the heights, then compare the two bars belonging to the same species. Exact numerical counts are unnecessary because the question asks which description supports the pattern. August 2026 8F, p.37, uses the same research context but a table and a maximum-ratio task. That earlier answer, 3.28 to 1, cannot be imported into this graph question, whose correct evidence is the consistency of the direction across three species.

Use the stated mechanism to explain an experimental result

R&W Module 1 Q14 · PDF p.15 · Answer: A

The passage defines the effort heuristic: awareness of labor invested in art can increase appreciation. Participants who watched robots creating paintings subsequently rated AI-created art more favorably. A links the observation to that mechanism: the videos challenged the assumption that the AI process involved little or no labor. It explains why seeing the making process could affect evaluation of the finished work.

B introduces anxiety about human artists losing jobs. C introduces intentionality. D introduces the influence of human art on AI output. Those ideas may be relevant to other discussions of AI art, but none is the explanatory variable developed here. Choosing one would require importing a premise that the passage never supplies. A needs only the definition already given and the contrast between viewers who did and did not see the videos.

The random labels in the first study also matter: the paintings were AI-generated even when labeled human-created. The initial score difference therefore supports a role for perceived origin rather than establishing that actual human-made paintings were aesthetically better. On review, write the two studies separately: a label changes perceived origin, while a video changes perceived effort. Connecting those steps produces a more disciplined inference than relying on a general opinion about AI.

Read the timeline before evaluating the cross-text claim

R&W Module 2 Harder Q7 · PDF p.74 · Answer: B

Text 1 proposes that present-day clades could trace back to Gondwanan species carried away when Grande Terre separated around 80 million years ago. Text 2 reports a 41.1-million-year crown age for a relatively old present-day clade and 9.0 million years for another, while saying nearly all current species belong to younger clades. Those dates are substantially more recent than the split. B best expresses the implication within the texts: few, if any, of the old Gondwanan species belonged to clades containing the island’s current species.

A turns the 9.0-million-year age of one beetle clade into a recolonization date for most ancient species. C incorrectly assigns the 41.1-million-year limit to the Gondwanan clades discussed in Text 1, which by definition predate the 80-million-year split. D asserts widespread living descendants even though Text 2’s age evidence challenges that continuity. The trap is confusing the old species being discussed with the present-day clades being measured.

Place 80, 41.1, 37, and 9.0 on a timeline measured backward from today. Larger numbers mean older events. The question does not require a general biological claim about every possible lineage: it asks what this author would most likely agree with based on these passages. Compared with August 2025 8E, pp.25–26, the clades, ages, and wording of the final question change, so the comparison must be rebuilt.

Find the squared radius and stop at the requested quantity

Math Module 1 Q20 · PDF p.120 · Answer: A: 81π

The equation is x²−10x+y²−4y=52. Complete the square separately in x and y: add 25 for the x terms and 4 for the y terms, adding both to the right side as well. The result is (x−5)²+(y−2)²=81. Therefore the center is (5,2), the radius is 9, and the area is πr²=81π, answer A.

The requested area makes the squared radius especially convenient. There is no need to take a square root and then square it again. B, 52π, treats the original right-hand constant as r² and ignores the square-completion adjustments. D, 9π, uses the radius where area requires its square. C, 26π, does not follow from the completed equation. Naming the target before calculating prevents these intermediate values from becoming accidental final answers.

An efficient mental check is that 52+25+4=81, a perfect square. You can also expand the completed form to recover the original equation and confirm both center signs. September 2026 9D, p.145, asks for a radius from different coefficients and requires √165. The methods are related, but November asks for area, so even a correct radius is only an intermediate result.

Squaring creates a candidate that the original equation rejects

Math Module 2 Easier Q20 · PDF p.147 · Answer: C: 9/2

The radical bar covers x²−25x+315, and the equation is √(x²−25x+315)=x√11. The left side is nonnegative, so any solution must have x≥0. Squaring gives x²−25x+315=11x², or 10x²+25x−315=0. Factoring yields (2x−9)(5x+35)=0, producing candidates x=9/2 and x=−7.

Only 9/2 satisfies the sign condition. At x=−7, the squared equation is true, but the original left side is positive while the right side is negative. At x=9/2, the radicand equals 11(9/2)² and the principal square root equals (9/2)√11, so the candidate checks. The answer is C. Keeping both roots confuses an implication with an equivalence: the original equation implies its square, but the squared equation need not imply the original.

You can reject −7 before calculating any radical because of the sign restriction. This is more efficient than separately evaluating both sides numerically. It also explains the answer more clearly than saying the calculator rejected a value. On a review sheet, record the restriction before the first algebra line. That small step protects against the same error in equations with absolute values, square roots, and squared expressions.

Clear denominators only after recording excluded inputs

Math Module 2 Harder Q16 · PDF p.170 · Answer: 7.5

The function is w(r)=1/(r−5)−(r−9)/(−r+3.75). A zero requires the two fractions to be equal, with r≠5 and r≠3.75. Cross-multiplying gives −r+3.75=(r−9)(r−5). Expanding and collecting terms gives r²−13r+41.25=0. The discriminant is 169−165=4, so r=(13±2)/2, or 5.5 and 7.5. The greatest possible value is 7.5.

Both candidates avoid the excluded inputs. A direct check of the larger one is short: 1/(7.5−5)=0.4 and (7.5−9)/(−7.5+3.75)=0.4, so their difference is zero. The printed key on p.177 also lists 15/2 or 7.5, consistent with this independent solution. The requested greatest value matters: finding one valid zero does not finish the task.

The most likely algebra error is dropping the minus sign in −r+3.75 or moving the second fraction without changing its sign correctly. Keep the equality of fractions visible before multiplying. A graph can help locate the zeros, but apparent discontinuities at 3.75 and 5 are not zeros. A denominator exclusion remains in force even if a later polynomial calculation seems to offer an attractive answer.

Eight verified comparisons with earlier papers

These are selected question-level comparisons, not an estimate of whole-paper overlap. A near-repeat retains most wording or reasoning; a retune changes details or quantities; reused context can change the claim itself; a skill analogue shares a method without being the same question.

2026 10A → 11B p.9

Reused passage with reordered and revised options. The Defoe passage and main-idea demand are retained from October, while the correct qualification about source trustworthiness moves from B to D. One distractor is also recast around being proved wrong. The central idea is neither unquestioning trust nor a ban on particular sources: historians should disclose the evidential status of the account. The comparison tests whether the reader remembers a proposition rather than a letter.

2026 10H → 11B p.47

Reused evidence context with a changed target. October’s graph prompt seeks an unchanged count that still exceeds other countries; November seeks countries moving in opposite directions. Sweden is replaced by Belgium in the background, while Gabon’s increase and the Philippines’ decrease provide the relevant contrast. A stable-country statement can remain factually accurate but cease to be the answer. Read the sentence immediately before the blank again when a familiar graph returns.

2026 10K → 11B p.55

Near-verbatim passage with reordered choices. Both versions explain regional authenticity in Italian cheese through local ingredients and methods. The second clause restates what authenticity means, making that is the correct relationship. Its position changes from C in October to D in November. Then would imply sequence, still concession, and rather correction. The names of cheeses are not what decides the transition; the explanatory function of the second clause is.

2026 10 17 schoolday 2 → 11B p.56

Retuned sequence. October’s pomegranate rind and yellow color become eastern cottonwood and orange. The final removal of the cloth follows soaking and simmering in both versions. Last becomes Finally, and the correct position moves from A to D. This is a close structural repeat, but the words still need to be read because a sequence transition is justified by the actions, not by the mere appearance of a dyeing topic.

2026 8F → 11B p.13

Reused research context, changed representation and question. August presents four species in a table and asks for the largest opposite-to-same ratio, 3.28 to 1. November presents three species in a bar graph and asks for support of an opposite-orientation tendency. The transferable skill is comparing the appropriate categories; the actual task changes from selecting an extreme numerical ratio to describing a consistent within-species relationship.

2025 8E → 11B p.74

Reused cross-text setup with numerical and inferential retuning. August gives crown ages of 59.9 million years for leaf beetles and 22.9 million for Pycnandra plants. November uses 41.1 million for stick insects and 9.0 million for beetles. Both retain the 80-million-year split and 37-million-year submergence boundary. November asks about the ancient Gondwanan species rather than directly classifying the two named modern clades, so track the referent as well as the dates.

2024 3D → 11B p.79

Retuned scientific-evidence passage. The 2024 source begins with degrading permafrost and bristle-pointed iris; November begins with lengthening growing seasons and Siberian peashrub. The model comparison remains 1 km² versus 10 km² cells. A difference in autumn respiration between resolutions supports the claim about coarse models, whereas a seasonal difference shared by both resolutions does not. The correct statement moves from A to C despite the same underlying evidentiary distinction.

2026 9D → 11B p.120

Skill analogue with different coefficients and requested quantity. September has x²+12x+y²=10y+104, which becomes (x+6)²+(y−5)²=165 and asks for radius √165. November becomes (x−5)²+(y−2)²=81 and asks for area 81π. This is not a verbatim repeat. It is a useful paired drill in completing both squares and reading whether the required result is radius, diameter, or area.

A focused study plan for this form

Start by pairing the leaf graph with August 8F’s table. Say aloud what comparison each question asks for before reading its choices. Then return to the AI-art case and separate the label manipulation from the video manipulation. The goal is to identify a mechanism from supplied evidence without substituting a broader opinion about the subject.

For the island passages, make a four-date timeline and label each number with its event or clade. Do not leave bare numbers on the page. The common mistake is attaching a correct age to the wrong population. Follow with the October Defoe and cheese questions and explain the right answers without letters; this exposes whether recognition has become a useful paraphrase or only a memory of choice position.

In Math, build a three-row checklist: requested quantity, excluded or restricted values, and verification. For the circle, the target is area. For the radical, x must be nonnegative. For the rational function, 3.75 and 5 are excluded, and the greater of two valid zeros is required. These are different constraints and should not be collapsed into a vague reminder to be careful.

Five concrete habits to carry forward are to compare bars within the relevant category, match the strength of words such as tend and all, attach every historical date to its referent, record restrictions before squaring, and verify the selected rational zero in the original function. Redo the alternate module later with familiar items marked as previously seen. A correct response after recognition still has instructional value, but it should not be mistaken for a fresh timed result.
