I found this practice question of TOEIC on another forum.
The tests in this fashion are designed with one grammatical error, which is needed to be picked out.SEEM unlikely, POLITICS sometimes INFLUENCE business DECISIONS.
The key answer is A, in which "seem" should be changed to "seemed."
Seemed unlikely, politics sometimes influence business decisions.
Why is not "seeming" but "seemed"?
I know "seemed unlikely" is expressed in passive voice, but which is the dropped subject? (It seems not to be "politics.")
Can anyone rephrase it in a sentence with nothing dropped?
