The owner of a cold store advertises that of the potato lots his store held last year only 2 in every hundred were refused by buyers on the ground of rot, and holds that his is the best-run cold store in the belt. Which of the following, if true, most weakens the owner's claim?

The owner's 2 in a hundred sounds well until somebody says what the belt does, and the option says it: every other store in the belt did better, several of them four times better. His figure, which looked like a boast, turns out to be the worst in the trade, and the claim to be best-run collapses on the very measure he chose. The age and capacity of the store describe the plant. Who keeps the record raises a doubt about the figure's honesty, which is a lesser objection and one the option does not establish. And a slightly higher rent bears on what a depositor pays, not on how the potatoes come out.
