Assertion (A): The mean growth rate of a droplet population understates how quickly the first raindrops appear.
Reason (R): A small minority of drops collect far more often than the average by chance.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: B

Both are true and the reason gives why the mean misleads, and rain onset is governed by the tail of the distribution. This was the central insight that made stochastic collection theory necessary. The mean is the wrong statistic for a threshold process.
