Jabberwocky## Can you help explain what B

## Answer choice B suggests that

Answer choice B suggests that it might be useful to know what fraction (or percentage) of all jimmylegs sufferers are LONGHAIRED jabberwockies.

For example, out of 100 jimmylegs sufferers perhaps 20 are longhaired. Or perhaps 30 are longhaired. etc.

## Thank you!

## Hey again!

So I chose B when I did it but after you went over A it made me consider it more. Why is A wrong? What if there are 100 medium haired jabberwockies and 100 of them get jimmylegs compared to the 200 out of 1000 shorthaired jabberwockies with jimmylegs?

Also around what difficulty is this question, I am trying to build gauge of question levels?

thanks again!!

## It really comes down to the

It really comes down to the argument's conclusion. The author says that LONGHAIRED jabberwockies are NOT predisposed to getting jimmylegs. This conclusion is based on the fact that more SHORTHAIRED jabberwockies contract jimmylegs.

The main problem with the author's conclusion is that, in order to determine whether LONGHAIRED jabberwockies are predisposed to getting jimmylegs, we need to know the RATE at which LONGHAIRED jabberwockies get jimmylegs. We then need to compare this with the RATE at which NON-LONGHAIRED jabberwockies get jimmylegs.

So, it doesn't matter how many varieties of NON-LONGHAIRED jabberwockies there are.

Does that help?

Cheers,

Brent

PS: I'd say this question is in the 600-650 difficulty range
