Quick Questions

Shade in the A or B circle for each question.

1. A computer program looks at a car's symptoms and suggests which part is faulty. Is this intelligent behaviour?

A No, only humans can ever diagnose faults

B Yes, diagnosing a fault normally needs human thinking

2. Which statement about a chess program choosing a good move is correct?

A It shows intelligent behaviour by choosing a move a human would need to think about

B It is not intelligent because chess is only a game

3. Does a computer that shows intelligent behaviour truly understand what it is doing?

A Yes, it understands just like a human

B No, it only simulates thinking

4. Which task shows intelligent behaviour?

A Recognising a pattern in photos to tell cats from dogs

B Adding 2 + 2 using a fixed calculator button

5. What does intelligent behaviour in a computer mean?

A Doing a task that normally needs human thinking

B Having feelings and real understanding like a person

Answer Key

Intelligent behaviour in a computer

Section A: Quick Questions

B — Yes, diagnosing a fault normally needs human thinking

A — It shows intelligent behaviour by choosing a move a human would need to think about

B — No, it only simulates thinking

A — Recognising a pattern in photos to tell cats from dogs

A — Doing a task that normally needs human thinking

Section B: Match the Pairs

intelligent behaviour → A computer does a task that normally needs human thinking, such as diagnosing a fault or choosing a game move

simulates thinking → The computer copies the results of human thinking using data and rules, but it does not truly understand what it is doing

Diagnosing a problem is intelligent behaviour because a doctor or engineer would normally need to think to do it → IF symptom = "no power" THEN OUTPUT "Check the battery"

Choosing a move in a game is intelligent behaviour because a human player would need to think ahead → best_move ← CHOOSE_BEST(board)

A chess program understands chess the way a human player does, so it truly thinks. → The program only simulates thinking by following rules and data. It does not truly understand the game like a person.

A calculator adding 2 + 2 is intelligent behaviour because it uses a fixed formula. → Simple fixed calculations do not need human thinking such as diagnosing or choosing. Intelligent behaviour means doing tasks that normally need human thought.

Section C: Definitions

intelligent behaviour — A computer does a task that normally needs human thinking, like diagnosing a fault or choosing a game move, but it only simulates thinking and does not truly understand.

Section D: Fill in the Blanks

IF fault = "no power" THEN
  OUTPUT "Check the cable"
ENDIF

IF newScore > bestScore THEN
  bestMove ← move
ENDIF

IF shape = "circle" AND colour = "red" THEN
  OUTPUT "Red ball"
ENDIF

simulatesThinking ← TRUE
understands ← FALSE
OUTPUT understands

INPUT symptom
diagnosis ← lookup(symptom)
OUTPUT diagnosis

Section E: Spot the Error

B — The text flat battery must be in quotes so it is stored as a string. Without quotes the computer looks for a variable called flat. It should be fault ← "flat battery".

B — When can_win is true, the game AI should choose the winning move, not block. Line 2 should be move ← WinningMove().

C — An IF statement must end with THEN. Line 3 should be IF a[i] <> a[i+1] THEN so the pattern check (a change between neighbours) works.

D — A condition must compare values with =, not assign with ←. Line 4 should be IF symptom = "fever" THEN.

A — A computer that shows intelligent behaviour only simulates thinking and does not truly understand. Line 1 should set understands ← FALSE.
