For the first question, the correct answer is:

For the second question, the correct answer is:
"Zeus, the king of the gods, is father of Athena."

To check if the sentences are punctuated correctly, we need to look at the rules of punctuation. Here are the correct answers:

1. Which of the following sentences is punctuated correctly?
- On January 1, 2000, many people thought that the new millennium would bring the end of the world, but it didn't.

To correctly punctuate this sentence, we need to use a comma to separate the date ("January 1, 2000") from the rest of the sentence. Another comma is needed after the word "world" to separate the two independent clauses ("many people thought that the new millennium would bring the end of the world" and "but it didn't").

2. Which of the following sentences is punctuated correctly?
- Zeus, the king of the gods, is father of Athena.

To correctly punctuate this sentence, we need to use commas to set off the phrase "the king of the gods" as well as the name "Athena" as additional information about Zeus.

So, the correct answers are:
1. On January 1, 2000, many people thought that the new millennium would bring the end of the world, but it didn't.
2. Zeus, the king of the gods, is father of Athena.
