Question 128·Medium·Text Structure and Purpose
Mrs. Langford paused at the threshold of the classroom, surveying the bright faces turned toward her. She cleared her throat, but her smile remained steady. What she said next seemed less addressed to her students than to herself. "We begin, not because we are ready, but because the moment asks it of us," she announced. The students looked at one another, unsure whether to nod or take notes, until Mrs. Langford strode to the board and began writing dates in bold strokes.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
For SAT “function in the passage” questions, bracket the underlined sentence and read one or two sentences before and after it. Identify whether it explains, transitions, contrasts, or interprets the surrounding ideas. Then eliminate choices that focus on the wrong subject (e.g., the students instead of Mrs. Langford) or describe something that happens in a different part of the passage (like a later reaction).
Hints
Locate what comes right before and after
Re-read the sentence just before the underlined part and the sentence with the spoken quotation after it. Ask yourself: how does the underlined sentence connect these two?
Ask who the sentence is mainly about
Notice whether the underlined sentence is focusing on Mrs. Langford, the students, or the narrator’s opinion. This can help you eliminate choices that focus on the wrong group.
Decide whether it looks forward or backward
Does the underlined sentence seem to be hinting at something that will happen later, commenting on what already happened, or helping you understand what is about to be said?
Match each option to what the sentence actually does
Take each answer choice and check: does the underlined sentence really perform that role in the paragraph, or is that role handled by a different sentence?
Step-by-step Explanation
Identify the task: function in the passage
The question asks about the function of the underlined sentence in the overall structure of the text. That means you need to determine what role this sentence plays in connecting or explaining the surrounding sentences, not just what it literally says.
Read the underlined sentence in context
Before the underlined sentence, the narrator describes Mrs. Langford’s actions and composure. The underlined sentence then comments that what she says next seems directed more to herself. Immediately after, the text provides the quotation she says out loud.
State what role the sentence plays
The underlined sentence gives an interpretive lens for the quotation: Mrs. Langford’s words function like self-encouragement, so readers understand her mindset as she speaks.
Match that role to the best option
Choices about the students’ later uncertainty or the class’s reaction don’t match, because the underlined sentence focuses on Mrs. Langford’s inner direction rather than the students. The best match is: It explains Mrs. Langford’s mindset before the quotation that follows.
