Answer Explanation

[PASSAGE] "Student loans are probably the most common form of financial aid. It’s essentially money you borrow for school. And this is the big one: You have to pay it back..." The professor says that loans are money you borrow, and crucially, they must be repaid. [WHY CORRECT] Option 2 is correct because the phrase "And this is the big one" directly precedes the statement about repayment, explicitly signaling that this is the most important characteristic of a loan among all the characteristics he has discussed or will discuss. He's differentiating it from 'gift aid' where repayment isn't required. [TRAPS] Option 1 is incorrect because there's no indication of a previous misstatement; he's introducing new information. Option 3 is incorrect; the professor previously called 'gift aid' the "best kind" of financial aid, not loans. Option 4 is incorrect; he continues to discuss loans (work-study) after this statement, making it part of the current topic. [TIP] When a question asks for the purpose of a spoken phrase, pay close attention to the speaker's tone, the words immediately preceding and following the phrase, and how it connects to the overall topic being discussed. Look for transitional phrases or intensifiers.

Why the Other Options Are Incorrect

• Option A (“To correct a previous misstatement”) misreads the speaker’s purpose for the remark.
• Option C (“To indicate that loans are the best form of financial aid”) treats a rhetorical aside as a literal claim.
• Option D (“To signal that he is about to move to a new topic”) assigns an intent the context does not support.

Key Language in Context

The language describing Financial Aid rewards close reading: notice contrast markers, hedging, and emphasis, since TOEFL function items hinge on nuance rather than matching keywords.

Skill Takeaway

Listen for the intent behind the wording, especially after signal phrases.
