Explanation:

Correct Answer is (a).The key words/phrases in the sentence are 'boost' and 'increase in pressure' and the use of either "composed (which goes absurd in the context)" or "invented" goes absurd in the context and hence options D and E can be eliminated. Moreover, a turbocharger is an equipment which actually 'forces' or 'generates' extra air into the combustion chamber and this confirms the word "generated" as an appropriate choice for the first blank.
The sentence further talks about the increase in pressure which points towards the word "exceeds" which logically completes the sentence.
Option A is hence the correct answer.
