Section B: Match the Pairs
Q1
} else if (score >= 70) { ... } → Checks this condition only if the earlier if was false
Q2
} else if (age < 18) { ... } → Runs its block only if age < 18 and the first if was false
Q3
Adds another condition to check after an if → else if
Q4
Only one block in a chain of these runs → if / else if / else if
Q5
} elseif (score >= 70) { ... } → Wrong - 'else if' needs a space between the words
Q6
} Else if (age < 18) { ... } → Wrong - 'else' must be lowercase
