Example answers and how they were marked
An embedded system.
Why: Correct name of the type of computer system (1).
A microcontroller.
Why: Near miss: a microcontroller is a component inside an embedded system, not the name of the type of system, so the 'Do not accept' line applies and it scores nothing.
A general purpose computer.
Why: Misconception: the stem states the system only performs the tasks needed to sell tickets, so 'Do not accept general purpose computer' applies and it scores nothing.
