We have changed X of Y more easily than A of B.

Any one of the following is wrong if we want to maintain the meaning of the above sentence.

We have changed Y more easily than B.
We have changed Y and B.

The same logic is applied in this sentence.

The difference between A and E is one of meaning change in E. The question demonstrates a comparison between how much change occurred in the US and how much occurred for foreign corporations.

Answer choice E simply (and wrongly) gets rid of the comparison and changes the meaning from US corporations' strategies to simply those of the US. So E changes the meaning on two counts. Also (don't know if it is a mistake in copying), United States should be preceded by the article 'the'.

IMO-A
E is out because not showing the comparison.

Thanks Isaac,

the question as it is. how I found it on a previous thread,

Your explanation makes sense, E is grammatically correct but goes too far and alters meaning.
