Question 1
A student must be at least 13 years old OR in grade 9 or higher to attend camp, but must NOT yet be 18 years old. Which Boolean expression correctly represents eligibility?
Question 2
Which Boolean expression evaluates to true if and ONLY if num is even?
Question 3
Which expression evaluates to true if n is a two-digit integer (10-99 inclusive)?
Question 4
What does this code display?
count ← 0 FOR EACH item IN [5, 12, 7, 20, 3] { IF (item > 10) { count ← count + 1 } } DISPLAY(count)
Question 5
Consider this algorithm that counts elements in a list greater than 100. Steps 3 and 4 are missing:

Step 1: Set count to 0 and position to 1
Step 2: If element at position > 100, increase count by 1
Step 3: ?
Step 4: ?
Step 5: Display count

Which completes the algorithm correctly?
