I have enclosed my term paper on the effects of pollution on municipal drinking water. My sources are listed at the end of the paper, and I have included all the necessary footnotes.
Which sentence most likely comes next?
1. Wait until you see the numbers on phosphate contamination.
2. I look forward to receiving your feedback on my efforts.
3. The part about the reservoir pollution is totally gross!
4. What a cool book—you'd love it.
