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.
