Answer Key

Condition

Section A: Quick Questions

A — Is it raining?

B — Is the score above 10?

A — False

B — True

A — True or false

Section B: Match the Pairs

IF it is raining THEN → 'it is raining' is the condition: a yes/no question that is either true or false

score > 10 → A condition with numbers that is true when the score is above 10, and false if it is not

A condition is a yes/no question about the situation → Is the door open?

A condition can only ever have the answer true or false → Is the score above 10? true

IF what is your favourite colour THEN → This is not a condition. It cannot be answered with true or false. Fix it with a yes/no question like 'Is your favourite colour blue?'

IF score THEN → A number on its own is not a question. Fix it by asking a true/false question such as 'score > 10'.

Section C: Definitions

condition — A question about the situation that can only be answered true or false (yes or no), like 'Is it raining?' or 'Is the score above 10?'. It helps an algorithm decide what to do.

Section D: Fill in the Blanks

IF raining = true THEN
  SAY "Take an umbrella"

IF score > 10 THEN
  SAY "You win!"

IF raining = true THEN
  SAY "Take an umbrella"

score ← 4
score > 10 is false

score ← 12
IF score > 10 THEN
  SAY "Great job!"

Section E: Spot the Error

C — A condition must be a question that is true or false. score + target gives a number, not true or false. It should compare them, like score > target.

C — The answer to 'Is it raining?' can only be TRUE or FALSE, so it can't be checked against 7. The condition should be raining = TRUE.

D — 'A big number' is vague, so the computer can't answer it with true or false. A condition needs a clear test, like score > limit.

C — ← stores a value; it does not ask a question. The condition should use = to ask 'Is the light green?', so IF light = 'green' THEN.

B — The message is for people aged 10 or older. The condition 'Is age 10 or less?' asks the wrong question. It should be age >= 10.
