Circle the best answer.

1.Which of these transfers information by a pattern?
  • A.A drum beaten at random
  • B.A drum beaten in a rhythm that means 'come here'
  • C.A drum left silent
2.Why do some codes repeat each message twice?
  • A.To fill time
  • B.To use more battery
  • C.So a missed part can be caught the second time
3.A message arrives with one flash missing. What can happen?
  • A.The message gets shorter
  • B.The pattern is misread, so the information is wrong
  • C.Nothing changes
4.Why must both people know the code before it is used?
  • A.To save the battery
  • B.Otherwise the pattern carries no meaning to the receiver
  • C.To be polite
5.Why is a pattern better than a single signal for sending words?
  • A.Different patterns can stand for different things
  • B.Single signals are illegal
  • C.Patterns are prettier
6.Two designs send the same message. How would you compare them?
  • A.Ask which looks better
  • B.Count how often the message arrives correctly
  • C.Measure which is heavier
7.Long and short flashes stand for letters. What makes that a code?
  • A.An agreed pattern that stands for information
  • B.The colour of the torch
  • C.The brightness
8.Which is more reliable over a long distance at night?
  • A.A whispered pattern
  • B.A pattern of small taps
  • C.A pattern of bright flashes
