C

Hi @Maria-Marin, Thanks for the question! This one has a lot of parts to it, so let’s take a look at what the stimulus is telling us. I’ll diagram it out: WHM = wig has handmade components ME = more expensive MTMW = made to measure wig RME = ranges from medium-priced to expensive HF = handmade foundations WWH = wigs with human fair DC = should be dry cleaned WHM —> ME MTMW —> RME ~WHH —> ~HF (or, less confusing, HF —> WHH) WHH —> DC Conclusion: MTMW —> DC? OK, so now let’s take a look at the correct answer to see why it works. (A) is right, because (A) gives us: RME —> HF And then we can conclude RME —> HF —> WHH —> DC Which means that MTMW —> RME —> HF —> WHH —> DC or MTMW —> DC which is what the conclusion is. Now let’s take (C). (C) gives us that a wig with handmade components should be dry-cleaned. The problem with (C) is that it doesn’t give a link between a wig having hand-made components and anything else, such as being made-to-measure, and so (C) alone won’t justify the author’s conclusion. Having hand-made components needs to be linked to other parts of the stimulus, and that doesn’t happen. Hope this helps. Feel free to ask any further questions that you might have.
