Multiple-choice

Passage:

It was the early days of disco, when making music and
light shows was the rage. Everyone wanted to buy a box
that could connect to their stereo to create new light and
sound effects. I started building boxes after school,
buying components from a nearby Radio Shack, and
reading up on electronic recipes for building loaders in
the basement workshop. I began buying voltmeters,
soldering irons, and other tools for making light organs to
sell at school and in my neighborhood. I made enough
money to stock more and more equipment in the family
basement
