To find out which sentence needs to be eliminated, we have to frame a paragraph with the other three and see if it is cogent. We can look out for key words or thoughts that link all sentences together with one main idea. Sentence A talks of developing “these different ways of thinking” by “extended, focused mental effort”. Sentence B talks of the “relatively brief period” students spend in a classroom, and “long term memory structures” required for subject mastery. Sentence C talks of how a traditional science instructor teaches assuming “expert-like ways of thinking” are already present. We can see right away that C and A go together, with the “way of thinking” being the key idea repeated in both sentences. Sentence D talks of how the “necessary extended effort” can be made by students with some help from teachers. Sentence A also talked of the “extended mental effort” students need to put in to develop expert-like thinking. So D ties in with A. The paragraph makes sense when arranged in the sequence CAD Looking at B, we can reconfirm that it is indeed the sentence to be eliminated as it talks of “memory structure”. This idea is not explained by any of the other sentences. Correct Answer: Choice (b)
