SAT — main purpose of a text

On the digital SAT, every Reading and Writing question comes with its own short passage of 25 to 150 words, drawn from literature, history and social studies, the humanities or science. One of the most frequent questions in the Craft and Structure domain asks for the main purpose of the whole passage: not what one sentence says, but what the writer set out to do. The answer choices usually begin with a verb such as to describe, to explain, to argue, to criticize, to illustrate or to present a finding, and the wrong choices are built to tempt: one fits a single detail, one overstates the claim, one describes something the passage never does.

This material trains that question across all four subject areas. Five items quote literature published in the United States before 1931: a village described by Sarah Orne Jewett, two poems in which the images serve an idea (Emily Dickinson on the majority's verdict on sanity, Sara Teasdale's "There Will Come Soft Rains"), the opening of Stephen Crane's The Red Badge of Courage, and a passage of Charles W. Chesnutt's "The Wife of His Youth" whose purpose depends on reading its irony. Seven original passages cover a botanical study, a finding about birdsong, the way a comet forms its tails, the early United States land survey as an example of maps doing political work, a theater critic's objection to a label, a weaver's method and a study of why farmers' markets survive. The passages ask you to tell describing from arguing, complicating a view from rejecting it, and giving an example from making a claim.

Each explanation shows which words in the passage decide the answer and names what is wrong with each of the other choices, so that the same reasoning can be reused on new passages. The flashcards collect the purpose verbs that the answer choices rely on (qualify, illustrate, challenge, complicate, describe, argue), the typical traps of too narrow and too strong options, and where a passage's purpose usually shows: in its first sentence and in turning words such as "but" and "yet."

The material offers a quiz and a flashcard deck. Practice material written by Zestly for students preparing for the SAT; it is not produced or endorsed by the College Board.

• Identify the main purpose of a short passage as a whole rather than the content of one sentence
• Distinguish purpose verbs such as describe, explain, argue, criticize, illustrate, qualify and complicate
• Recognize irony in fiction and poetry and state what it is used to criticize
• Reject answer choices that are too narrow, too strong, unmentioned or contradicted
• Use a passage's opening claim or question and its turning words to find its purpose
