Read it wrong, picked A

Wish I could have attended this. Any estimate when it will be put up with the other webinars?

POE on this one. Lot of bad ACs

significant number = some?

ugh why was this one so hard for me

Flaw? Some = Some, when we know some doesn't equal some. (Invalid Arg. Form 7)

some Smog Reaches Unsafe Levels

Hot Days

some Wind Blows from the East.

Therefore, one some days when the wind blows from the east, smog reaches unsafe levels.

Really? How can we equate that. Now, if you replace ALL with Wind Blows East, then you can make that assumption.

A) In my opinion, I eliminated A right away because they weren't mistaking any condition to be necessary or not.

B)As long as you're able to identify the flaw (some = some) then choosing answer B should be easy despite the abstract language. When we talk about relationships like this we generally use the term "common" "one set"

C, D) Irrelevant

E) The flaw isn't causation, it's mistaking some = some

Great explanation

Is the flaw lack of evidence whens it doesn't exist?

Very good explanation, thanks!
