I am just totally lost on this one. Can anyone please help me. I don't even know how to eliminate the wrong one here . especially the Powerscore back paged answer doesn't really explain doesn't stick well with me this occasion (10-135)

"Biologists have proposed two mechanisms that bacteria might use" - that's two hypotheses being discussed or suggested. The passage goes on to say that if one is correct, certain behavior would be observed, but if the other was correct, different behavior would be observed. Finally, the author says the evidence supports one over the other, presumably based on which behavior was actually observed. That's what answer B describes - two hypotheses, a way to tell which one is correct, and evidence supporting one over the other.

Hi Team - may I know why Answer Choice C is incorrect given that Answer Choice B and C are so similiar - that the only difference in Answer Choice C is about the "flaw inherent" mentioned while Answer Choice B saying the other one is "more accurate"?

Many thanks!

That's exactly why C is wrong, christinecwt - the third paragraph says nothing about any flaws in either hypothesis. Instead, it just explains what would be true in each case. In order to select answer C you would have to be able to point to the flaws mentioned in that paragraph. Can you find them? If not, cross that answer out!
