错选了 c,c是文章的目的。。。问题问的是f of p这本书是如何在文章中被描述的,定位如下:In Forces of Production, David Noble examines the transformation of the machine-tool industry as the industry moved from reliance on skilled artisans to automation. Noble writes from a Marxist perspective, and his central argument is that management, in its decisions to automate, conspired against labor: the power that the skilled machinists wielded in the industry was intolerable to management. 故d
"they" is totally wrong in (d). it would automatically refer to "neurons", since "canaries' " is possessive and therefore ineligible to be the referent.
if you say "when + PAST PARTICIPLE", then this automatically applies to the SUBJECT of the clause to which it's attached.
And the other thing wrong with A, B, C and D is "when placed in a stimulating environment" - it sounds like they are referring only to the time that the mice are in the stimulating environment - but the brain growth is permanent. It doesn't shrink back down once the mice are no longer in the stimulating environment. Ditto for the increase in neurons in the canaries.
Tough one. "examples of neurogenesis include" - so the examples should lead off with whatever the actual thing is that indicated neurogenesis. The mice aren't the example - the example is the brain growth. That eliminates B and C. A also breaks parallelism.

我一直认为原文是在讨论下卵的数量问题,跟size没什么关系啊,第一句确实说了suitable size,但是后面都没有说size的事情啊。但是又好像只有a可以从原文里推断出,其他的好像都需要脑补
c,they 指代是fertilizer,但是这里语义是肥料的使用导致了环境问题,而不是肥料本身导致了环境问题
C: COMMA + -ING modifiers must modify the preceding clause, but the -ING participle must also apply to the subject of the preceding clause.therefore, the use of that comma+ing modifier would imply that the islets themselves are stimulating disputes. that's not true.
