Answer: A.) At this point in his life he was familiar with the basic science of electricity.
Explanation: This answer makes the most sense out of all of them and the sentence gives reason enough to believe said character has some knowledge on the laws of electricity. Taking this based off the words "I was not unacquainted with the more obvious laws of electricity." Meaning said character had some prior knowledge, so we can assume he is familiar with the basic science of electricity.
A slimy blue thing was in my room.
I grabbed my cat, and looked down at my mat. It was so hard to sleep, so I got up and treaded on my feet. The creature was odd looking. It looked like a pile of pigs mud, but even more gooey and liquidized. This was the weirdest thing I have ever seen in my life. Then, my cat splashed the monster, so I went and reached to turn on my light. I felt silly for having a fright, for it was just my slime that my cat spilled water that made me feel grime.
The “winter dreams” of the story refer to the American Dream that Dexter<span> comes to embody, but success brings a high cost, and social mobility restricts Dexter’s capacity for happiness. Dexter is from humble origins: his mother was an immigrant who constantly struggled with the language of her adopted homeland. The central irony of the story is that realizing the American Dream yields bleak rewards. For example, when Dexter was a young caddy, he dreamed about success and wealth and the happiness they would bring. When he finally beats T. A. Hedrick in a golf tournament, however, the triumph brings him little joy. Dexter is able to transcend middle-class inertia but, despite his tireless efforts to advance his fortunes, forced to accept that money cannot buy happiness.</span>
