I am puzzled about how to decide when a THAT can be dropped in the following types of sentences:
1. The findings suggest one reason the pesticides may be harmful.
2. The findings suggest one reason THAT the pesticides may be harmful.
3. Scientists found X, findings consistent with the growth of the industry there.
4. Scientists found X, findings THAT are consistent with the growth of the industry there.
Here, per Verbal Review, #1 is wrong. #2,3,4 are all correct. All of these "sound" right to me, but I can't figure out an exact reason why #1 needs a THAT while the others don't.
Any idea?
