ANSWER ASAP IM TIMED Read the excerpt from The Boy Who Harnessed the Wind by William Kamkwamba.

One Saturday, Gilbert met me in the library and we flipped through books we thought might be fun. I couldn't study all the time. One book that caught my attention was the Malawi Junior Integrated Science book, used by Form Four students. Hmm, I thought, and flipped it open. There were lots of pictures and diagrams, which I found easy to understand. I saw pictures of cancer and scabies and children stricken with kwashiorkor, like so many who'd wandered the country. One picture had a man in a shiny silver suit walking on the moon.

What is the primary idea that the details in the excerpt tell a reader about Kamkwamba?

He has varied interests in reading material.
He is intelligent despite his lack of education.
He and Gilbert are good friends who share interests.
He is not really interested in studying.
