The MG discussion did not mention one aspect of the problem.
One incorrect choice says:
its most recent press release, the new management stated that it plans on expanding
The explanation mentioned that 'plan on' is not idiomatic. What about the aspect that a past tense verb (stated) introduces a subordinate clause that is of a present tense?
I think it is acceptable to say 'Newton discovered that the gravity pulls the apple to the ground' because the subordinate clause states a theory, a law or a universally accepted fact. But I think it is usually wrong for other situations, such as in the above example. Am I correct?
