In the following question, two statements and five connectors are given. Only one of the connectors from those given can be used to combine the given two statements into one sentence without changing the meaning. Choose that connector as your answer. 1. Personal responsibility is an attractive goal with deep roots in American culture. 2. If it's too aggressively pursued, it may conflict with another worthy ideal: In a nation as wealthy as the United States, sick humans deserve health care even if they can't pay, and even if they've made some bad choices.

(a) The sentences carry a contradictory relationship - 1 tells us that personal responsibility is an attractive goal, and 2 tells us that it can conflict with another ideal if its too aggressively pursued. BUT can be used to link contradictory sentences: "Personal responsibility is an attractive goal with deep roots in American culture, but it's too aggressively pursued, it may conflict with another worthy ideal: In a nation as wealthy as the United States, sick humans deserve health care even if they can't pay, and even if they've made some bad choices." Thus, (a) is the right answer. AS, FOR and SINCE are used to link sentences that share a cause-effect relationship, which is not the case here. UNLESS is used to denote conditionality, which is not the case here.
