Read the passage from president barack obama's back-to-school remarks.

maybe you could be a good writer—maybe even good enough to write a book or articles in a newspaper—but you might not know it until you write a paper for your english class. maybe you could be an innovator or an inventor—maybe even good enough to come up with the next iphone or a new medicine or vaccine—but you might not know it until you do a project for your science class.

in this section of the speech, the purpose of the parallel structure is to obama

a. emphasize his belief in the importance of being able to write well.
b. explain his thoughts on the best classes to take for a good education.
c. prove his point by spelling out the options available with an education.
d. strengthen his argument that more scientists are needed in the workforce.

prove his point by spelling out the options available with an education.

In his parallelism, he is showing that you'll realize your potential or interests in school while doing a project or writing an essay. The last part of the parallelism speaks about classes, so we know that his emphasis is on education. This eliminates the first and last options. He isn't necessarily choosing the best classes here, just using English and science as an example. This leaves the third option as the correct choice.

Parallelism is the repetition of a similar sentence or verb structure. The parallelism in the speech is the structure "Maybe you could be - maybe even good enough to - but you might not know it until you ".
