1. What data type is used to store the value: "hello world"?
Strings are used to store a sequence of characters like "hello world", ":)", "goodbye!".
2. What data type is used to store one of the two values: TRUE or FALSE?
Boolean (also known as bool) are used to store True or False values.
3. What does the operator "<=" mean?
The "<=" operator means that the first value is less than or equal to the second value.
4. Which operator means "equal to"?
The "==" operator mean that the first value is equal to the second value.
5. What does this boolean expression evaluate to: (5 < 5) or (2 >= 2 and 1 > 2)
"5 < 5" will evaluate to False. "2 >= 2" will evaluate to True. "1 > 2" will evaluate to False. As a result, the entire expression can be rewritten as: False or (True and False). "True and False" evaluate to False. Therefore, the expression is: False or False, which is False.
