This year, the Rocktown school district offered a free summer enrichment program called “History Rocks” to its rising fourth-grade students. Therefore, fourth graders in the Rocktown school district will score better this year on American history tests.

Each of the following, if true, would strengthen the author’s conclusion EXCEPT:

(A) “History Rocks” focuses entirely on American history.
(B) The majority of the district’s rising fourth graders attended the program.
(C) For the past five years, Rocktown students have scored lower, on average, on American history tests than have students in neighboring towns.
(D) The material on fourth-grade history tests in Rocktown is substantially similar to the material being covered in the enrichment program.
(E) It has been proven that students retain knowledge better when learning one subject at a time, as is the case in the “History Rocks” program

OFFICIAL EXPLANATION



(C) For the past five years, Rocktown students have scored lower, on average, on American history tests than have students in neighboring towns:



This EXCEPT question is a variation on a regular Strengthen question. The four incorrect answers will strengthen the argument. The correct answer will either weaken the argument or do nothing at all to it—but the correct answer will not strengthen the argument.

There are a great many assumptions in this argument. The argument assumes that students will actually sign up for and attend the free class.

It assumes that the material in “History Rocks” is the same kind of material tested on American history tests (maybe “History Rocks” teaches the history of Ancient Greece, for instance), and that the students will remember what they learned long enough to score well on tests during the upcoming school year.

Choices (A) and (D) strengthen by filling the gap related to whether “History Rocks” teaches the same kind of material tested on American history tests.

Choice (B) strengthens by filling the gap related to whether students will actually sign up for and attend the free class.

Choice (E) strengthens by filling the gap related to whether students will remember what they learned long enough to score well on tests during the upcoming school year.

Choice (C) provides information that might explain why Rocktown wants to offer the free summer program, but this information does not address whether the plan will work as intended. As such, it neither strengthens nor weakens the plan; it doesn’t address the plan at all.
