Answer 1

To edit the provided sentence correctly, we need to add punctuation marks to separate titles, names, and the time. Here's the original sentence with the necessary punctuation added:

"Professor Gray, Mr. Michaels, Dr. Gunn, and Ms. Foster usually arrived at the office by 8:30 a.m."

Now, counting the punctuation marks:

1. Comma after "Gray"
2. Period after "Mr"
3. Comma after "Michaels"
4. Period after "Dr"
5. Comma after "Gunn"
6. Period after "Ms"
7. Colon in "8:30"

Total: 7 punctuation marks.

So the correct answer is **7**.
