SAT — Information and Ideas, mixed set

The other materials in this category mostly take the question types of this domain one at a time. On the real section the Information and Ideas questions come as one block in each module, grouped by skill and ordered from easiest to hardest, so you meet every type in quick succession; this set mixes them so that noticing what is being asked becomes part of the exercise. Ten questions, no two of the same type together, in roughly balanced proportions — three central idea, two detail, two textual evidence, two inference, and one set of results to read.

The types reward different reflexes, and mixing them is what makes the reflexes worth having. A central idea question wants the claim the passage was built to make, which is often a correction of the view stated in its own first sentence. A detail question wants only what is on the page, and is failed most often by a choice that is a reasonable inference rather than a statement — one item here separates a butterfly's departure date from its speed of travel, which are easy to conflate when reading quickly. An inference question wants what follows and nothing more, and includes among its wrong answers a completion that simply restates a fact already given: true, harmless, and wrong after the words "it is therefore fair to say". A textual evidence question wants the finding that would change one's confidence in a claim, which for a comparative claim means whatever rules out the rival explanation. And a set of results wants the comparison the figures actually make — here two figures differ and two are identical, and the identical pair is in the passage precisely to catch a claim built on the wrong comparison.

Two items are worth attention after answering. The screen-and-sleep question asks what weakens a claim that names a mechanism, and the strongest attack is on the mechanism: remove the blue light with a filter, and see whether the effect survives. Its wrong answers include one that supports the claim, one that is merely compatible with it, and one that widens it — three different relationships to a claim, only one of which is damage. The marine reserve question asks the same skill in the supporting direction: the biologist argues the ban rather than the water, so the evidence she needs is that the water behaved identically inside and outside.

Every explanation names the question type first and says what that type asks for, then justifies the key and describes what is wrong with each other choice. Every study, researcher, institution, firm and work here is invented, and no invented finding is attributed to a real organization, journal or university. Nothing is reproduced from any College Board publication, released test, practice test, question bank or scoring guideline. The real section presents some results as graphs; here one question is read from a bar graph and the others give their results in sentences.

• Recognize which of the domain's question types is being asked before choosing an answer
• Find a passage's central claim, including when it corrects the view stated in its first line
• Answer a detail question from the page alone, refusing a reasonable inference in its place
• Complete a passage with what follows, and reject a completion that only restates a given fact
• Support a comparative claim by ruling out the explanation it argues against
• Attack a claim at its named mechanism rather than at whether any effect occurs
• Tell a finding that damages a claim from one that merely fails to help it
• Read a short set of figures for which comparison they make and which they do not
• Hold both halves of a balanced description when drawing a conclusion from it
• Notice when a writer declines to rank two things, and refuse an answer that ranks them

Written for this catalog, with no source document. The content is all four skills of the domain (central ideas and details, textual and quantitative command of evidence, inferences), as described publicly by the College Board for the Information and Ideas domain of the SAT Reading and Writing section; every passage, question, option and explanation here is original, and nothing is reproduced from any official publication or released test.
