For 26, I ruled out B because it referred to expectations regarding the "by-products."

I thought E was a better answer because it refers to bombardment of alternative substances, rather than their by-products

how do they expect us to know that information about relative ages within a generation? [nvm i misunderstood the answer choice]

bruh. How is 19 E anomalous? It literally says it "presents difficulties to numerous minority groups". I feel like it's so weak to say that it is anomalous purely because it is "particularly problematic"

I originally chose E, but changed my answer to B during blind review because the premises are based on history, whereas the conclusion refers to a time before the existence of historical records. I took this to be a contradiction, although I guess it isn't necessarily between two premises.

How is C the answer here? Just because a technique doesn't confront "every" argument, it should be avoided?

The "every" almost implies that the technique should attack every possibly argument (even ones that aren't addressed). You can still attack an opponent's argument by addressing only some parts of it; and attacking your opponent especially doesn't require addressing "every" argument. So I'm not sure how you can use that as a necessary clause for this scenario

With choice D, I was hung up on the "important" aspect of it

I didn't feel like having an "interest" in something is sufficient to it being "important", but I guess that is an assumption that we should make

If anything, I thought the "indifference" towards other species countered this choice

same. brutal

For B, I took "given the mechanisms by which the political process operates" as pointing towards how corporations influence the political process which results in funding promises not being fulfilled. I guess this was not a reasonable assumption—but if it was, wouldn't B be correct?

I don't love how these Skill Builder lessons are set up with each section containing the same type of structure. Once you get the first 1 or 2, it makes the rest of the questions in the section more obvious and you don't have to think about them as much.

"So you know if she goes to the store she must buy milk but she can buy milk and not go to the store?"

You're right, she CAN buy milk and not go to the store. That's because buying milk is not sufficient for going to the store.

But if she goes to the store, she must buy milk. It is necessary. The information says if she goes to the store, she buys milk. Maybe she could also order milk online. But we know that if she does not buy milk, then she did not go to the store. That's why it's a necessary condition.

Hopefully that helps

I agree, I immediately ruled out A because it said that confidence and accuracy are not correlated. Can someone explain why A still applies?

For 8.1 I thought it would be "The formation depends on conditions"

I'm confused as to why 'increased standards of living' are considered a financial benefit
