A grain depot's register shows, for five months, the sacks received and the sacks found damaged on arrival: January, 800 received and 40 damaged; February, 600 and 36; March, 1,000 and 40; April, 500 and 35; May, 900 and 45. Which of the following is best supported by the register?

The shares are 5, 6, 4, 7 and 5 per cent. May has the most damaged sacks at 45, yet April has the highest share at 7 per cent, so the two peaks fall in different months. March took the largest intake and had the lowest share, which sinks the first option; the shares run 5, 6, 4, 7, 5 rather than downward; and the damaged counts run 40, 36, 40, 35, 45, which is not a month-by-month fall.
