A laboratory replaced an ageing diesel pump with an electric model. The annual maintenance cost of the electric pump was lower than (A) ______ the diesel model, although the initial purchase price was higher. The operating instructions supplied with the new pump were also clearer than (B) ______ the older manual. They separated routine checks from procedures requiring a specialist. The laboratory did not infer that the electric model would be cheaper under every operating condition: its estimate assumed the same number of running hours and did not include the cost of a backup power supply. The comparison therefore concerned specified costs and instructions, not an unrestricted ranking of the two machines.

Our copying method requires fewer manual adjustments than theirs, although the two methods produce equally legible images. In a separate test, the texture of the paper used by our team differed from that of the paper used by the other team. The researchers recorded these distinctions without ranking the teams by skill. Fewer adjustments could make a method convenient for repeated copying, while a particular texture could be preferable for a different display purpose. Neither observation established that one method was superior for every task. The report kept the methods, the resulting images and the surfaces carrying those images as separate units of comparison.

The texture of a handmade sheet is rougher than (A) ______ a coated sheet. This difference affected how strongly light was reflected from the surface, but it did not determine the sharpness of every printed image. In the same trial, the colours reproduced on the handmade paper were less saturated than (B) ______ on the coated paper. The designer therefore recorded texture and reproduced colours separately rather than treating the name of the paper as a complete account of its performance.
