Read the excerpt from "On Becoming an Inventor" by Dean Kamen.

I decided to put his entire machine shop in our basement, but there were two problems... One, his shop wouldn't fit in our basement, and two, there was no way the lathe, weighing fifteen hundred pounds, and the milling machine, weighing two thousand pounds, could be carried into the basement. I solved this problem by hiring a contractor to dig a large hole, break open a wall of the basement, enclose the addition with concrete, and add a roof that could be used for building an outside deck to the house. I also enlarged my mother's kitchen and pantry. I now had the entire machine shop in our basement. At the time I was making enough money from my electronic devices to pay for all of this.

What conclusion can be drawn from the details in this excerpt?

Kamen's family did not appreciate the enlargement of their basement.
Kamen's mother had complained about the size of her kitchen and pantry.
Kamen's idea to enlarge the basement benefited both his work and his family.
Kamen's machine shop still did not fit into the newly enlarged basement.
