Organ tuner: Since the church put in heating, the Chalcombe organ has been tuned three times a year where once a year sufficed. Metal pipes take their pitch from their temperature, some ranks further than others, and the heating swings the nave nine degrees between Saturday night and Sunday noon. The heating is at least part of the reason the organ now needs tuning as often as it does.

Which one of the following, if true, most weakens the tuner's argument?

AThe organ's reed stops, whose pitch no swing of temperature the nave sees will shift, have needed the tuner's attention as often since the heating went in as the metal flue pipes beside them have.

BThe organist appointed in the year the heating went in has the organ tuned before each of the church's three festivals, whether or not its pitch has moved since the last.

CAn organ in an unheated church a mile from Chalcombe is tuned twice a year, and its nave has never been known to vary by more than two degrees in a week.

DThree tunings a year cost the parish more than the heating saves it in fuel, as the churchwardens have said.

EThe heating was put in to warm the congregation, with no thought for the instrument, and the faculty for the work never mentioned the organ.
