3. What is the difference between `=` and `==`?

A. `=` stores a value; `==` asks whether two values are equal. B. `=` asks whether two values are equal; `==` stores a value. C. Both store a value; neither asks a question. D. Both ask whether two values are equal; neither stores a value.

4. In `old_enough = age >= 10`, what is stored in `old_enough`, and why?

A. The number `10`. B. The text `"age >= 10"`. C. Nothing — the line gives an error. D. A boolean — the answer to the comparison `age >= 10`.

5. Why does lowercase `true` give an error?

A. Because `true` is a reserved word for numbers only. B. Python only recognizes the capitalized forms `True` and `False`. C. Because `true` must always be written in quotes. D. Because lowercase letters are not allowed in Python at all.
