Section B: Match the Pairs
Q1
FOR i FROM 1 TO 10 → Starts a loop counting i from 1 up to 10
Q2
END FOR → Closes a FOR loop block
Q3
A structure that repeats instructions a fixed number of times → FOR loop
Q4
The keyword that sets where the loop variable stops counting → TO
Q5
FOR i FROM 1 TO 10
DISPLAY i
ENDFOR → The closing keyword should be written as END FOR, not ENDFOR
Q6
FOR j FROM 1 TO 5
j = j + 1
END FOR → Assignment in pseudocode should use ←, not =

Q1
A — The keywords are in the wrong order — it should read FOR i FROM 1 TO 10.
Q2
B — VCAA pseudocode uses DISPLAY to output a value, not PRINT.
Q3
C — The closing keyword should be written as END FOR, not ENDFOR.
Q4
D — A FOR loop must be closed with END FOR, not END IF.
Q5
E — VCAA pseudocode closes a FOR loop with END FOR; NEXT i is not valid syntax.
