Question: Where is gasoline made?

Choices: 
- burn in oxygen
- refineries
- boat
- gas station
- rocks

The rationale to choose "refineries" as the answer is that: 

the gas station is where gasoline is sold, not made. rocks may be what gas is made from, but not where they are made. burn in oxygen maybe a characteristic of gasoline but not where its made. boat is where oxygen is userefineries is the only place that correlates to where gasoline is made.
