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.
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
