Questions #6 #10 #18

Hi! I completed the 50 questions in the workbook today and found myself stumbling on a couple questions. I was wondering if someone might be able to break down questions #6, #10, and #18 for me? I wasn't even sure where to start with those. I get lost in the context of the passage often times and then freeze up on how to approach it. Thanks!

Hi @Annief, thanks for reaching out.

When clicking view, I only see one question attached. Would it be possible for you to specifically reference the tests numbers, section, and question numbers for each of them? Or perhaps type out the first sentence, that way we can do a search quickly for those questions?

However, for now I'll answer this one attached. (About red/green colour blindness).

The passage makes the error of making a sufficient/necessary statement and then concluding that the reverse of this sufficient/necessary statement holds true as well.

Red green colour bind -> unable to distinguish between green and brown

Concludes

Unable to distinguish between green and brown -> Red green colour blind

It is not possible to infer that the necessary condition is also sufficient.

Answer choice B does this exact same reversal.

I hope this was one of the questions you wanted to see answered, but if not, please just specify the ones you were confused about and we will be sure to answer them!
