PART A: What is a central idea of the passage from Five Weeks in a Balloon?
A
When traveling, it is beneficial to choose a doctor as a travel companion.
B
Travelers can make important contributions to the studies of geology and science.
C
Alternative methods of travel may offer practical benefits as well as pleasurable experiences.
D
Traveling can create deep and everlasting bonds among people.

I believe it either C or D

Explanation: A isn't right because you don't always need a doctor for you travel companion. B isn't right either never talks about geology or science in the passage. C could be right because it gives Kennedy joy when he was riding the balloon, yes he might of been scared but it was cool. D also makes sense because it can create bonds with people.

for me i cant do homework without music, so, i guess i would say faster with it, than without it. for me at least.
