Answer Key
Keywords in capital letters
Section A: Quick Questions
Q1
A — IF Score > 50 THEN
Q2
B — FOR Count ← 1 TO 10
Q3
B — Keywords such as OUTPUT are written in upper case
Q4
A — ENDIF
Q5
A — TotalScore
Section B: Match the Pairs
Q1
IF Score > 50 THEN → IF and THEN are keywords, so they are written in capital letters
Q2
FOR Count ← 1 TO 10 → FOR and TO are keywords in capitals, and the loop is closed later by NEXT
Q3
An IF statement must be closed with its keyword ENDIF in capital letters → IF Age >= 16 THEN
OUTPUT "Allowed"
ENDIF
Q4
A FOR loop is closed with the keyword NEXT in capital letters → FOR Count ← 1 TO 5
OUTPUT Count
NEXT Count
Q5
if Score > 50 then → The keywords if and then are in lower case. They must be IF and THEN.
Q6
DECLARE NEXT : INTEGER → NEXT is a keyword, so it cannot be used as an identifier name. Use a name such as NextNumber.
Section C: Definitions
Q1
IF — A Cambridge pseudocode keyword. All keywords, such as IF, THEN, FOR, NEXT and OUTPUT, are written in capital letters, and they cannot be used as identifier names.Section D: Fill in the Blanks

Q1
C — OUTPUT is a Cambridge pseudocode keyword, so it must be written in capital letters. The line should be OUTPUT "Pass".
Q2
D — NEXT closes a FOR loop and is a keyword, so it must be in capital letters. The line should be NEXT Count.
Q3
C — NEXT is a keyword, so it cannot be used as an identifier name. Use a name such as Total instead.
Q4
B — IF is a keyword and must be written in capital letters. The line should be IF Mark > 90 THEN.
Q5
B — TO is a keyword in a FOR loop and must be in capital letters. The line should be FOR Num ← 1 TO 3.
