Answer 1

During recent research, genetic researchers have isolated the gene that determines the natural times a person sleeps and wakes.

Here's the issues with the sentence:

"During recent research," doesn't match the tense of "genetic researchers have isolated." 

"The natural times a person sleeps and wakes" is over explanatory, and should be simplified.

Research is repeated.

Answer: B. Genetic researchers recently isolated the gene that determines a person's natural sleep cycle.
