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.

invention of the washing machine

in the past, people used sticks and stones or scrub boards to clean their clothing. as it was sweaty, backbreaking work, we owe a world of to james king because he created the model for the modern washing machine in 1851. the most important issue was that this machine cleaned clothes while a person cranked the handle. doing this made people who used it develop strong muscles in their arms. later, in 1908, alva j. fisher created an electric washing machine named thor. this one was not the first automatic washing machine. however, it was one of the most popular models at the time.
