Quiz Questions, Three Levels Deep

A quiz app has three kinds of question. Each level adds one thing to the level above it.

Question(text, answer)

• check(guess) returns True if the guess matches the answer, ignoring capital letters and spaces at either end. So " paris " matches "Paris".

TimedQuestion(text, answer, seconds), a child of Question

• Stores seconds, the time limit. Let the parent set up text and answer.
• points(guess, taken) returns:
  • 0 if the guess is wrong,
  • 10 if it's right and taken is at most seconds,
  • 5 if it's right but too slow.

BonusQuestion(text, answer, seconds, bonus), a child of TimedQuestion

• bonus defaults to 5. Let the parent set up everything else.
• points(guess, taken) returns the parent's points, plus bonus only when the parent's points are 10.
