Answer: C Kamen's idea to enlarge the basement benefited both his work and his family.
Explanation: Kamen managed to fit all of his machines in the basement after he made it larger, and he also made the pantry and kitchen bigger to benefit his mom.
A Kamen's family did not appreciate the enlargement of their basement.
There is no mention of Kamen's family's opinion in the text.
B Kamen's mother had complained about the size of her kitchen and pantry.
Kamen's mother did not show her opinion in the text.
D Kamen's machine shop still did not fit into the newly enlarged basement.
His machine definitely fit into the basment, as seen here "I now had the entire machine shop in our basement."
I hope this helps. Have a nice day!
