The quantity of petrol can be increased by ___________?
Correct answer: C. Cracking
- A. Reforming
- B. Induction fueling
- C. Cracking
- D. Refining
Explanation
Cracking breaks large, less useful hydrocarbons into smaller hydrocarbons, including petrol-range molecules, so it increases the quantity of petrol obtained. The likely wrong choice is refining, which is the general purification and separation of crude oil, not specifically the process that makes smaller molecules.
