Given that Juan was very thorough studying for his exam and was shocked to see the results, the facts of the sentence suggest that the blanks should be filled by the fact that he did not do very well.

The sentence here makes clear that the chef loves to cook with red pepper. However, he has to be mindful to keep himself in control with the red pepper for a certain reason.

Therefore, the best answer is "to the same extent that he does."

Given that every other phrase in the sentence had problems, the best answer would be "overflowing with errors." This is the only phrase that is negative in connotation, reflecting the problems that exist with the sentence.
