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?

Sufficient condition... i think

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.
