One thing that makes the peachtree road race special is that it takes place each year on independence day. (1) american flags are waved down peachtree street, and nearly everywhere red, white, and blue is seen. many runners choose to wear stars-and-stripes as a part of their racing outfit, but no one is allowed to wear costumes in this serious race. that means no statues of liberty are officially allowed running down the road, as with other large festive races such as the bay-to-breakers 12k in san francisco. (2) because the peachtree is run on a holiday, most people have the day off. (3) they either run the race or cheer on the runners from either side of the street. there are tens of thousands of spectators all along the course.

which of these statements best summarizes the main idea of paragraph 2?
a) spectators and runners both make the race special.
b) the race is different than other races run on holidays.
c) people dress patriotically to celebrate independence day.
d) the peachtree is special because it is run on an important holiday.

D) The Peachtree is special because it is run on an important holiday.

Most of the passage discusses how the Peachtree Road Race is special because it takes place on Independence Day. This is stated from the beginning, in the first sentence. However, the idea is reinforced throughout the passage. The author tells us that because of the holiday, people dress in festive clothes. Also, because of the holiday, many people have the day off, which makes it very busy.

the support that the author, uses in the article facing our fears is a): a definition of the part of the brain called the amygdala.

he takes neuroscientist joseph ledoux's words by telling that by falling to distinguish between evolutionary old systems located in the amygdala and newer systems, centered in the prefrontal cortex, doctors have conflated non conscious threat circuits in the brain with circuits that underlie the conscious experience of fear. that, the author says, "leads ledoux to the jarring conclusion that the amygdala, a decades-old centerpiece of the brain's fear circuit, does not underlie the conscious feeling of fear".

despite this, the author points out in the article that that is a controversial notion and that evidence, in animal and humans, supports the idea that core emotions can exist outside of conscious awareness.
