This isn't exactly what we want the correct answer to do. We are not trying to weaken the principle. The question is asking us to understand the possible relationship between the principle and the claim. When we combine the correct answer with the principle, it should contradict the claim.
The claim is proposing an exact reason for Country X's decision to lower tariff barriers. According to the claim, the reason for this change is that it served the interests of foreign companies.
According to the principle, we can't say that the lower tariff barriers served the interests of those companies without explaining
how it served their interests. Notice that the claim doesn't do this. The claim just states that it did serve their interests without explaining how.
If choice (E) is true, there is no evidence that shows how the lower tariffs benefited the companies. So, if the principle is true, and choice (E) is also true, the claim isn't valid.
I hope this helps.
