The conclusion can be properly drawn if which one of the following is assumed?

(A) As long as secondary school students are taught with methods appropriate to their learning styles, they will devote significant effort to their studies.

(B) Even if secondary school students are taught with methods appropriate to their learning styles, they will not achieve broad mastery of the curriculum if they do not devote significant effort to their studies.

(C) Secondary school students do not achieve broad mastery of the cuniculum if they are not taught with methods appropliate to their learning styles.

(D) Teaching secondary school students with methods appropriate to their learning styles does not always result in broad mastery of the curriculum by those students.

(E) Secondary school students who devote significant effort to their studies do not always achieve broad mastery of the curriculum.

Secondary school students achieve broad mastery of the curriculum if

a) they are taught with methods appropriate to their learning styles and

b) they devote significant effort to their studies.

conclusion-

Thus, if such broad mastery is not achieved by the students in a particular secondary school, those students are not being taught with methods appropriate to their learning styles.

What about second part - "they devote significant effort to their studies"

(A) As long as secondary school students are taught with methods appropriate to their learning styles, they will devote significant effort to their studies.

CORRECT.. this makes point b as a subset of point a, thus only point a is to be worried about(B) Even if secondary school students are taught with methods appropriate to their learning styles, they will not achieve broad mastery of the curriculum if they do not devote significant effort to their studies.

this rather weakens. so point b is important(C) Secondary school students do not achieve broad mastery of the cuniculum if they are not taught with methods appropliate to their learning styles.

repeats what is there in para(D) Teaching secondary school students with methods appropriate to their learning styles does not always result in broad mastery of the curriculum by those students.

again does not support conclusion(E) Secondary school students who devote significant effort to their studies do not always achieve broad mastery of the curriculum.

again , does nothing to conclusionA
