NameDate

Circle the best answer.

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