What it tests

Text Structure and Purpose asks what a text is doing: the main purpose of the whole passage, or the function of one underlined sentence within it. The answer choices are almost always verbs of function — introduces, qualifies, illustrates, refutes, concedes — rather than restatements of content.

How to approach it

Ask "what job does this sentence do for the paragraph?", not "what does this sentence say?". Read the sentence before and after the underlined one — a sentence's function is defined by its neighbours. Then check each choice's verb first: if the verb is wrong, the rest of the choice does not matter, however accurately it summarises the content.

The mistake that costs the most points

Choosing the answer that accurately restates the sentence. A choice can describe the content perfectly and still be wrong, because the question asked for the function. Test each choice by reading only its verb against the passage before reading its object.

What a Text Structure and Purpose question looks like

The report's introduction lists four possible causes of a factory's declining output before stating that each subsequent section will examine the evidence for one of the four causes in turn.

Which choice best describes the function of the introduction?

  1. A It dismisses three of the four causes as implausible before any evidence is given.
  2. B It provides a final, definitive conclusion the report simply restates later.
  3. C It previews the report's organizational structure for the reader.
  4. D It narrates the factory's founding and early history.

Answer: C. Explicitly telling the reader what each subsequent section will do is a structural preview, not a premature conclusion, a historical narrative, or a dismissal made before evidence is presented.
