What is the topic sentence
I think it is sentence 3 please let me know if you think it is as well
Voice mail is usually part of your firm’s phone system. It is a way to digitally record messages, and it allows “random access” so you can skip, delete, save, and forward messages. Voice mail can be one of your most important business tools. Using it effectively allows you to time-shift (you take your calls only when it’s convenient for you) and place-shift (you can check your messages while you are away from your desk).
1. First sentence (Voice mail is . . . )
2. Second sentence (It is . . . )
3. Third sentence (Voice mail can . . . )
4. Fourth sentence (Using it . . . )
Yes, that is your topic sentence.
