A study found that students in charter schools, schools that run independently of the school boards that run regular public schools, are performening worse on average than students in regular public schools. Another study found, however, that perfromance tends to drop when students change schools. Researchers maintain that the lower average performance of charter school students can be attributed to their having changed schools to attend the charter schools.

Which of the following, if true, provides the most support for the researchers' explanation?

A. students in urban charter schools tended to perform better than those in rural ones.

B. many charter schools were established in order to instruct students who were performing poorly in school.

C. Many students who transferred from one regular public school to another began to perform better in mathematics but performed worse in english.

D. A high percentage of the charter schools studied had been opened within the six months prior to the study.

E. School boards are often more effective at securing funds than charter schools.

D seems to be the clear answer.

Last sentence is the conclusion. Conclusion highlights "change in school". D shows how it can be true

I think it's B... it clearly talks about the performance of students... if D were true, a couple of years from now, charter schools would catch up with public schools in performance, which probably is not what the passage is implying. Also, passage talks about 2 independent studies, it is unclear which study D is referring to.

I think B is fine.

B. many charter schools were established in order to instruct students who were performing poorly in school.

Stimulus states that one of the main reasons being suggested is change of school for poor performance: B clearly says that charter schools are for pupils who could not do well in regular schools, thus pupils change over to charter schools with poor performance hoping to imrove their performance. No one guarantees that changing to charter school would boost poor performed pupil's grades. it takes a lot of work and student still keeps getting low grades. Overal: charter schools full of "dummy" pupils doesnt show good results.

I think B support researcher's explanation.

B gives an alternate explanation for the researcher's conclusion ie already poorly performing students.
D strengthens the conclusion by stating that there is possibly no other reason except change in schools for the the poor avg performance within such a small time period of 6 months.

D is the only one with relevant information. Since many charter schools were opened in 6 months prior to the study, a percentage of students would have moved to charter schools in the last 6 months.
