Jack: want to check out the movie "into the wild" tonight? jill: ok, if we can take the new parkway, we will get there in half an hour. what type of cause is jill claiming that taking the new parkway is?

The right answer is "Cause as sufficient condition"

Explanation:

A condition A is sufficient for a condition B if and only if the truth (existence or occurrence) of A assurances or brings about the truth of B. In other words, A guarantees B, meaning event A produces event B. In the example above, the condition A might be "take the new parkway", the condition B is "get there in half an hour". Taking the new parkway guarantees getting there in half an hour.

Sufficient condition ... i think
