That sentence is so complex, it should come with an instruction manual! It's a compound-complex sentence.

To determine the type of sentence, we need to analyze the structure and the number of independent and dependent clauses.

For the first question:
"My name, Cynthia, is from a Greek word for moon."
This is a simple sentence because it consists of only one independent clause, "My name, Cynthia, is from a Greek word for moon."

For the second question:
"I was not surprised when I learned that."
This is also a simple sentence because it consists of only one independent clause, "I was not surprised when I learned that."

For the third question:
"After all, I have always been a night owl, and I prefer moonlight to sunlight."
This is a compound-complex sentence because it contains multiple independent clauses and at least one dependent clause. The independent clauses are "I have always been a night owl" and "I prefer moonlight to sunlight." The dependent clause is "After all."

Therefore, the correct answers are:
1. a. simple sentence
2. a. simple sentence
3. d. compound-complex sentence
