Q5
A — True
Section B: Match the Pairs
Q1
define addNumbers(a, b) → Starts a function named addNumbers with two parameters
Q2
end function → Closes a function definition
Q3
A keyword that starts a function's definition and names it → define
Q4
Values listed in brackets after the function name that the function accepts → (a, b)
Q5
DEFINE greetUser(name)
DISPLAY "Hello " + name
end function → The keyword should be written in lowercase as define, not DEFINE
Q6
define subtract(a, b)
result ← a - b
DISPLAY result
func end → The closing keywords should be written as end function, not func end
