prep 139[these 和they的指代问题]

Lujs8061

139. Besides adding complementary flavors（增加味道） to many foods, hot sauces stimulate the release of endorphins in the brain, just as exercise does, and these have a pain-relieving effect like morphine's.

A. hot sauces stimulate the release of endorphins in the brain, just as exercise does, and these
  have a pain-relieving effect like morphine's

B. hot sauces stimulate the release of endorphins in the brain, like exercise, and they have a pain-relieving effect that is like morphine

 

A: correct

B: they 指代不清；effect like morphine不对称（NN的解释）

暂且不管B项中的其他错误，俺不懂的是为什么A项中these没有指代不清的问题，B项中的they就有这个问题呢？

My god, so many questions I have， shame on it!

没人解答？

no, no shame for asking a great question. "so many questions I have", that sounds like master Yoda's talking.  May the force be with you....

I think you have a valid argument here. "These" and "They" should either both be correct or both be wrong. Personally, I would rather use "they" in answer A,  or changing it to "these hot sauces has a pain-killing..." would sound better.

these must be used here, since they must refer to people, or a group of things related to people. but you're right, these can refer to sauses or endorphins, still unclear. but it's already better than "they"

in GMAT, you need to pick the best answer among five but the answer might not be the most "effective" answer if there were some other choices.

I hope I answer the question.

Please explain:

OG46: A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they require less medication and gain weight quicker than those raised in confinement --- they = calves

OG129: their wines are priced to sell, and they do --- they = wines

与B的比较对象不对等问题，A的these问题只是相对性错误

在比较中升华！
