1. True/False: In an if... structure, the only possible outcomes are either: a block of statements are executed or nothing is executed.

2. True/False: A valid test condition could be (x = 10), assuming x is an integer variable.

3. True/False: The following test condition for an if... structure will be true if x = 2:

if(x < 5 && x > 10)

4. True/False: The result of any test condition is always either true or false.

5. True/False: The following test condition will evaluate to true if x = 5:

if(x < 3 || x == 5)

6. True/False: The following statements are equivalent, given that x = 4 and y = 3:

z = Math.pow(y, x);

and z = x * x * x;

7. True/False: While it is possible to nest an if...else structure within an if... structure, it is not possible to nest an if... structure inside if...else structure.

8. True/False: The if clause and the else clause of an if...else structure must always contain different test conditions.

9. True/False: If an if clause or an else clause contain only one statement, curly brackets are not necessary.

10. True/False: A switch structure is a multiple alternative selection structure.
