B — It exists as coins and banknotes you can touch

A — They hand over coins or notes to the cashier

A — The cash is lost and usually cannot be recovered

B — Banknote: a piece of paper or plastic money

Section B: Match the Pairs

coins and banknotes → The two physical forms of cash: metal coins and paper or plastic notes

Physical money is handed over in person to pay in a shop → pay = hand_over(cash)

Physical money can be lost or stolen because it is a real object you carry → wallet = wallet - lost_cash

physical money = a number stored only on a computer → This describes digital currency. Physical money is real coins and notes you can hold in your hand.

cash needs no making or moving → Wrong: physical money has to be made (coins minted, notes printed) and moved, for example by delivery to banks and shops.

Section C: Definitions

physical money — Cash in the form of coins and notes that you can hold in your hand and hand over to pay for things, unlike digital currency, which exists only electronically.

Section D: Fill in the Blanks

price ← 4
IF cash >= price THEN
    OUTPUT "Paid"

cash ← 20
price ← 6
cash ← cash - price

cash ← 20
stolen ← TRUE
IF stolen = TRUE THEN cash ← 0

coins ← 5
notes ← 2
total ← coins + notes

paid ← TRUE
IF paid = TRUE THEN
    OUTPUT "Cash handed over"

Section E: Spot the Error

B — The change from a cash payment is the cash handed over minus the price, so it should be change ← 5.00 - price. The broken line gives a negative amount.

D — When you hand over cash in a shop, you have less of it. It should be wallet ← wallet - spend, not +.

C — An IF statement needs the keyword THEN after the condition. It should be IF lost = TRUE THEN. Lost cash is gone, so cash becomes 0.

D — The line should output the change the shop gives back. It outputs price instead of the variable change.

B — A count-controlled FOR loop uses TO for its end value. It should be FOR i ← 1 TO 3, which adds up three 2p coins.
