Q14: I guessed B because all the other answers seemed wrong, but I had absolutely no clue the difference between a thermostat and a thermometer before blind review.

A thermostat affects/influences temperature, while a thermometer merely reflects temperature, which is analogous to the passages. I may be oversimplifying, but it helps to understand the passages this way:

Passage A: Markets are distinct and powerful in their efficiency. In other words, markets can affect/influence people.

Passage B: There is nothing special about markets, they just reflect the majority opinion at any given point in time. In other words, people affect/influence markets.

I'm late to this but given there are no explanations for this section I figure I would add my two cents: E is incorrect because it is describing the historians' attitudes towards the laws themselves which is the wrong focus. The passage only addresses how the legal and labor historians describe British feminists' interpretation/oppositions to the laws. The passage does NOT cover how these historians feel about the laws themselves.

I don't see any written explanation explaining why E is not correct, so here is my interpretation:

I was stuck between D and E. I chose E when timed and quickly realized D was correct during blind review.

The question stem is asking us to identify how Engle is interpreting McKinley's remarks. E is incorrect because this answer choice is identifying Engle's interpretation, not McKinley's. Engle's misinterpreted McKinley's remarks to mean that the various "effects" refer to the drug's efficacy, rather than its side effects. So Engle is the one who is "confused," not McKinley.

One thing I don't think he covers in the explanation video here that makes it much easier to answer this question is inference-making from "some" and "most" relationships.

The premises can be written as...

"Stress is a common cause of HBP" (all we know is that stress causes HBP for some people)

Stress ←s→ HBP

and

Exercise ‑m→ Calm → Reduce Stress ←s→ Lower Blood Pressure

E becomes the obvious correct answer because it states that

E ←s→ Reduce Stress, which is an inference you can make from Exercise ‑m→ Calm → Reduce Stress

Got the correct answer, but I can't help but imagine a world where D is the correct answer because Hampton does not explicitly deny that human beings won't increase the percentage of the world's land now devoted to agriculture. Hampton only says that humans won't significantly increase the percentage of the world's land now devoted to agriculture.

I know D is not a strong answer and I know B is correct, but if B were not an answer choice, D wouldn't strike me as being explicitly incorrect; it seems that D is vague enough to be correct compared to the other incorrect answers.

A is a trap answer choice. I think the reason why many people chose A, myself included at first, is because we read the stimulus and thought the stimulus was making an assumption that deep tilling CAUSES topsoil erosion without considering that topsoil might CAUSE farmers to deep till as an intervention.

But the stimulus never actually assumes this. When we are told that "deep tilling is even more deleterious than previously believed," this is all the information we need to conclude that deep tilling IS deleterious. So there is no flawed reasoning. We can safely conclude that deep tilling is BAD for topsoil erosion.

Additionally, even if this flaw of confusing cause for effect were present, "Topsoil erosion does not make farmers want to till more deeply" is NOT the same as "Farmers that till more deeply would experience even worse topsoil erosion if they didn't use deep tilling methods." The former statement isn't a necessary assumption; it's masquerading as one.
