问题 The author had trouble operating his VCR because
It seems that manufacturers will remain reluctant to make improvements unless______.

选项 A、they can do so at a very low cost
B、they find their machines hard to operate
C、they have difficulty selling their products
D、they receive a lot of complaints about their machines

答案C

解析答案依据就在第二段最后一句话当中：If manufacturers can get away with selling products that are difficult to use it is not worth the effort of any one of them to make improvements．若生产制造商能够把难以使用的产品卖出去，那谁还舍得花力气去改进这些产品呢?C项意思是生产制造商很能把产品卖出去的话，他们才会努力改进产品。显然C项与原文内容是符合的。正确答案是 C。
