Question

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 help Obama

1: emphasize his belief in the importance of being able to write well.

2: explain his thoughts on the best classes to take for a good education.

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

4: strengthen his argument that more scientists are needed in the workforce

Answer 1

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

Obama talks about different professions in the speech, they aren't just limited to science or writing. This eliminates Options 1 and 2 as possibilities. Also he is not saying that you should take specific classes, but rather you should try and do your best in every class, because you never know which class may provide you with inspiration or the skills you need later in life.
