2. Most teens could not imagine going to bed at 7 p.m. every night, but Kelvin would. Then, in the middle of the night, he would wake up to transform his living room. It was a "small electronics scrapyard," as Kelvin explained. Kelvin was always very interested in technology and inventions, but he lived very poorly. His community did not have modern technology. This did not stop Kelvin. He scrounged through scrapyards and dumps looking for basic components to make his inventions work.

Which phrase best describes the central idea for paragraph 2?

A. His community did not have modern conveniences, but he found a way to make inventions.
B. He scrounged through scrapyards and dumps looking for basic components to make his inventions work.
C.Most teens could not imagine going to bed at 7 p.m. every night, but Kelvin would.
D. In the middle of the night he would turn his living room into a small electronics scrapyard.

All options possess information that is indeed in the paragraph. We are, however, looking for its central idea, the topic the paragraph revolves around. The most important thing about Kelvin is the fact that he found a way to make his inventions work, even though his community didn't offer him the proper conditions for it. And he did so by sifting through scrapyards and dumps to find the components he needed. But the way he did it, as well as the time he went to bed, and his making a mess of his living room are just additional information to support the main idea. It functions as evidence to prove the central idea true. It all leads to the fact that Kelvin was driven enough to make his inventions work in spite of the lacking conditions in his community.
