The sentences that use the word "convey" correctly are:
- The wheel will convey the dough to the ovens, where it will bake.
- I think I need to add a description to really convey the experience.
The other sentences use "convey" incorrectly. In the first, "convey" should be "discuss" or "communicate," and in the third, "convey" is incorrectly used; it seems like it should refer to "push" or "press."
