**Is it a subset?**

Let \( C \) denote the set of all house cats.

1) \(\emptyset \subset C \) is
- \( \bigcirc \) True
- \( \bigcirc \) False

2) How many cats does \(\emptyset\) have?
- \( \bigcirc \) No cats!
- \( \bigcirc \) 0 cats!

Let \( E = \{ \{ 1, 2 \} \} \) and let \( F = \{ \emptyset, E \} \).

1) How many elements does \( E \) contain?
