Grower: The tomato houses fitted with the new diffusing glass gave a heavier crop last season than the houses left under clear glass. What the season showed is not that diffusing glass lifts yield. Diffusing glass went to the south end of the site, and the south end is where the heating pipes were renewed two winters ago; heat, not light, is what this crop has been short of.

Which one of the following, if true, most strengthens the grower's argument?

AThrough the coldest nights the renewed pipes hold the south-end houses a degree and a half warmer than the north end's, and tomatoes are not indifferent to that.

BTwo north-end houses were reglazed with diffusing glass this spring, heating untouched, and both are setting fruit sooner than the clear-glazed houses beside them.

CThe north-end houses, whose pipes were renewed this spring under glass left unchanged, are carrying no less fruit at this stage than the south-end houses carried at the same stage last year.

DThe cucumber houses, never reglazed and on their original pipes, carried no heavier a crop last season than the lightest tomato house under either glass.

EDiffusing glass costs more to install than clear glass and has to be washed twice a season rather than once.
