hey everybody... had a question on
AAMC 9 question # 13
i got the question correct, but i had a different though process and wanted to know if my thought process was another way to get to the same answer or if it was just luck.
My thought process:
The passage states that gasoline w/out additives can be inefficient. So adding in an anti-knock compound will increase
efficiency. Then the passage also says that the higher the octane rating, the slower it burns and
smoother the piston operates. I took smoother to be less knocking aka more efficient.
So from that I figured, high octane rating = high(er) efficiency. So when the question asked for what uses the least oxygen, I took that as what is the most efficient with oxygen? So I just paralleled them calling a fuel with a high octane rating as efficient with efficiency with oxygen. So I picked EtOH because it had the highest octane rating and thus I thought it had the highest efficiency and highest oxygen-consuming efficiency. Is this valid or just luck?

also, on specifically #112 (but passage 3 of BS in general), what is the definition of filtration rate? i assumed it was the rate at which "stuff" was filtered out meaning really huge stuff would be "filtration rate"d out a lot aka filtered out a lot. but i'm trying to understand the reasoning and it seems inverse to what i was thinking.
