Hi!

I was wondering if A would have been a Good answer if it said:

mistake a condition that sometimes accompanies unsafe smog with one that is SUFFFICIENT for it.

Say the sun is sufficent for smog: sun --> smog

The other stays the same: wind blows <-s-> sun

Put these together: wind blows <-s-> sun --> smog

Use Dave's some train and boom wind blows <-s-> smog

Now we can see why the author came to that conclusion! Thus my version of A would be an answer?

Thank you! I'm trying to get a little creative :-D

Hi Adam!

I totally get the answer, I was just seeing if my approach to a slightly altered question would have been good!

Yes, Diana, that would have worked, and your breakdown is correct. If "hot days" was sufficient for unsafe smog, and there were some hot days that also had the wind blowing from the east, then on at least those hot days there would be both unsafe smog and wind from the east, and the author's conclusion would have been correct rather than flawed. Nicely done!

I have read the explanation of this question from the LR Bible. I understand why B is right, but I have some questions about E.

Is it true that there is no evidence of a correlation between smog and wind blowing? That is, since we don't know that those two occur on the same day, there is no evidence of a correlation? And if those two did occur on the same day, would that be considered a correlation?

If someone could answer those questions and further elaborate on why E is wrong, I'd appreciate it.
