Question

which is good English to say in tree distribution trainings or for tree distribution trainings

Answer 1

The correct phrase would depend on the context in which you are using it. If you are referring to training materials or sessions that cover tree distribution, "for tree distribution training" would be appropriate. If you are talking about groupings or categories of trainings that focus specifically on tree distribution, you might say "in tree distribution training."

In summary:
- Use **"for tree distribution training"** if you are indicating purpose.
- Use **"in tree distribution training"** if you are referring to the context or field.
