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 test


Which of the following, if true, would NOT strengthen the author's conclusion?

A - "History Rocks" focuses entirely on American history.
B- The majority of the district's rising fourth graders attended the program.
C- The district decided to make the program free because many students in the area come from low-income families.
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.

Confused between C & D

Hi Ashima123,

The conclusion is "fourth graders in the Rocktown school district will score better this year on American history test" based on the fact that the Rocktown school district has offered a free summer enrichment program called "History Rocks" to its rising fourth-grade students. Now, we want an option that helps support the conclusion i.e. students will score better.

A - "History Rocks" focuses entirely on American history. - Definitely supports!
B- The majority of the district's rising fourth graders attended the program. - If most students attended the program, then the chances of students scoring higher is more (although the option does not talk about American History)
C- The district decided to make the program free because many students in the area come from low-income families. - This one focuses only on a part of the premise i.e. free education. However, that is in no way connected to the conclusion i.e. scoring better. So, this one does not strengthen the conclusion and should be the answer.
D- The material on fourth-grade history tests in Rocktown is substantially similar to the material being covered in the enrichment program. - If the material on the tests and the material in the program is similar, then obviously students to attend the program will do well on the test. So this strengthens the conclusion.
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. - This one strengthens the conclusion as well since it shows a clear connection between the program and scoring better (retaining knowledge)

Hope this helps :-)

i think option D is not worded properly :
D- The material on fourth-grade history tests in Rocktown is substantially similar to the material being covered in the enrichment program.
"Fourth grade history tests" does not mean "American history test" ..it can be two separate tests ...

Although I answered the question correctly, I am not satisfied with the quality of question. Both options 'B' and 'C' are irrelevant to the conclusion that "Rocktown school district will score better this year on American history test"

Confused between C & D



C talks about the free program while the conclusion is that " fourth graders in the Rocktown school district will score better this year on American history test" . So C does not strengthen the conclusion. --Correct
B says majority students attended, so the probability is high that they will score better as they attended the program

But the conclusion says fourth graders in Rocktown school district "will score" better this year on American History test. Don't you think that the conclusion implies that all students of fourth grade will get a better score and not the majority. Hence this could be a weakener too, right?
