A: to produce
B: producing
答案是第一个为什么?

本题的答案是B，绝对不可能选A，因为：
这是SPEND 的固定结构 SPNED STH (IN) DOING STH/SPEND TIME (ON) DOING STH,表用尽，消耗，使竭尽,
本句有情态动词COULD, 但此处 THEY COULD 用来修饰限定AS MUCH AS TIME AS, 而不是修饰限定 PRODUCE 的。

A. to produce

因为这里有could，也就是can，can后面不能加ing形式。

选B. spend time (on) doing sth 其中on 可以省略

A: to produce

答案绝对是第二个。they could 是状语从句，你要看主句，主句是：spend...doing sth.
