Which detail from the text best supports the answer to Part A? O A "More recently, consensus moved toward the idea that yawning cools
downlige brain, so when ambient conditions and temperature of the
brain itself increase, yawning episodes increase." ( Paragraph 4)
OB "When you see someone else yawn, the networks in your brain
responsible for empathy and social skills are activated."
(Paragraph 9)

once again tested contagious yawning in canines while controlling for
stress." ( Paragraph 11)
OD "Levels of the cortisol stress hormone did not rise in dogs that didn't
yawn in response to a human yawn. This finding suggests some dogs
find human yawning stressful and others do not." ( Paragraph 12)

B "When you see someone else yawn, the networks in your brain

responsible for empathy and social skills are activated."

Explanation:

(Since I don't have much information and I don't have Part A this seems to be the best answer)

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
