Hi there,

What is the right porcess to resolve this SC ? Please explain. OA is E

According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about equivalent to the enrollment of the nation's four-year colleges and universities.

(A) equivalent to the enrollment of
(B) the equivalent of those enrolled in
(C) equal to those who are enrolled in
(D) as many as the enrollment of
(E) as many as are enrolled in

equivalent- comparing characters.

equal - comparing accurate measurements.(height,distance,)

as many as - approx number

Here 8 million people are compared to number of students.

options with "Equivalent" and "equal" are therefore wrong.So A and B are out.

8 million cannot be counted accurately when people are concerned so as the number of students in universities.Its just an approx no.

D and E are left.

Option E is comparing 8 million people with "enrollment of students" which is not logical.

Option E compares 8 million with no. of students which is logical and hence correct answer.
