Logical reasoning PrepTest 144 · Section 2 · Question 13

Incorrect. The argument doesn't discuss those who do support extending trade to other Latin American countries, so this answer is out of scope.

Incorrect. Similar to (A), this answer discusses politicians who currently support extending trade to Latin American countries, and the stimulus is about those who don't, so this answer is out of scope.

Incorrect. There's no indication that support for free trade among the three countries was based in a support for free trade among all countries, so there may not be a shift in position in refusing to support the inclusion of other Latin American countries in the trade agreement.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
Some people who supported free trade between three countries now don't support including other countries.

Answer Anticipation:
There's not much to summarize or anticipate in this.

Answer Explanation:
This answer flips the quantifier around from "Some . . . don't" to "Not all . . . do."
That's a valid rephrasing—those quantifiers carry the same meaning—so this is the correct answer.

Key Takeaway:
It's rare, but some Must Be True questions are testing your ability to rephrase key concepts, including quantifiers. This entire question hinges on your ability to translate "some don't" to "not all do." It can be a good reminder to work on your quantifier recognition if you had trouble here!

Incorrect. The stimulus establishes that some of these politicians refuse to publicly support extending free trade to other countries, but that doesn't mean that they're publicly opposing it—they could be silent on the issue.
