RC Question 15 Explanation, by LSATHacks
DISCUSSION: This is a bit of a hard question. I had to check a few of the answers against the passage. I found B and C tempting, but they both contain terms that don’t match the passages.
___________
- CORRECT. See lines 3-5 in passage A, and 36-38 in passage B.
I don’t love this answer, because I’m not sure passage B is “primarily concerned” with the agricultural record. They seem more specifically concerned with the tooth health of the Ban Chiang populations. But passage B is at least concerned with the development of agriculture in that population, so this is the best answer. - “Overall health” is why this is wrong. Both passages were only concerned with tooth decay.
- “Strictly agricultural societies” is why this is wrong. Passage A talks about tooth decay in nonagricultural populations (paragraph 3) and passage B says the Ban Chiang groups were not entirely agricultural – they ate some wild foods (lines 54-54).
- Neither passage mentions the first agricultural society. Passage B, in particular, only talks about Thailand.
- This is a general answer. Neither passage talks about hunter-gatherer carbohydrate availability in general.

For the explanation for answer B:
Passage B states “agricultural intensification results in declining human health, including dental health.” One might argue that “overall health” might pertain to Passage B? The answer still be wrong of course because passage A makes no mention of overall health
Lawhub says A is correct for this question.
