My struggle with Q11 was primarily that I zoned in on paragraphs 1-3 and missed the last paragraph completely. I knew I was filling in gaps/making assumptions for the answer choices I picked to work; if I hadn’t allowed myself to get so narrowly focused I could have at least gotten this one in BR.

In Flaw questions, our first two criteria for judging answer choices are:

1) Is this something the argument actually does?

2) Is this a reason why it’s hard for me to reach the conclusion based on the premise(s) in the argument?

With AC B, the first criteria is met; the argument does overlook this. But with the second, B doesn’t point out a flaw. With most question types in general, we need to stay within the bounds the stimulus laid out for us and here in a Flaw question, the right answer choice HAS to state something flawed about the way the argument based its conclusion off of the premise(s). B is pointing out some brand new consideration that’s irrelevant to the argument, and almost seems to make a sufficiency/necessity confusion (Stim: Should Overstate>Reduces Injuries, B: Overstate>Always Reduces Injuries).

Sometimes it also helps to make an analogous argument with more familiar pieces:

“One should shake hands with others only if they want to be friendly. However, people shake hands with others merely because they’re trying to avoid making enemies. Therefore, people should not shake hands with others.”

Is this argument flawed because B) I didn’t consider that not shaking hands with others does not always come across as being friendly?

Hope that helps, and kudos to you for studying through the holidays!

I was down to B and E, and I think one of the issues that led me to choose B was that I totally ignored the context in the first portion of the stimulus, instead zoning in on the premise and conclusion to justify B. The second thing I, and maybe many other people, missed, was that B refers to “traffic laws”, while the support in the stimulus refers to “actual average speed”, which is totally different from a “traffic law”. With this additional discrepancy, B can’t possibly enable us to reach the conclusion from the premises in the stimulus.
