Station manager: Five years ago a third of our recorded listening was to the evening programmes; this year it is a half. Over the same five years the afternoon's share fell from a quarter to a fifth. Nothing else about the schedule changed. So the evening programmes have gained listeners and the afternoon ones have lost them.

Which one of the following arguments contains flawed reasoning most similar to that in the argument above?

ATwo years ago the late-night slots drew a third of the plays begun; now a half. The breakfast slots' share has gone from a quarter to a fifth. Nothing else about the output changed and the count of plays begun is unmoved. So late-night has won audience and breakfast has shed it.

BThree years ago a third of the reading room's seats were taken by students; now a half are, and the pensioners' share has gone from a quarter to a fifth. So students value the room more than they did and pensioners less.

CFour years ago a third of our audience panel put the mid-morning slots first; now a half do, and the tea-time slots' share has gone from a quarter to a fifth. Nothing else about the panel changed, and it is made of people who wrote in. So mid-morning is now the more widely liked and tea-time the less.

DSix years ago the orchard was underplanted with clover. Since then the crop off the old trees has risen by a third and that off the young has fallen by a fifth. Nothing else about the orchard changed. So the clover has fed the old trees and starved the young.

ESeven years ago a third of the bed-nights we let went to walkers; now a half do, and the cyclists' share has gone from a quarter to a fifth. Nothing else about the hostel altered. So walkers take more of our beds than they did and cyclists fewer.
