Passage One
One of the most interesting experiments in electronic communication I’ve ever seen is coming from Wave. It’s real-time e-mail. What that means is that as you’re typing a message in Wave, either a new message or a reply, the person you’re writing to can see what you’re typing as you type it. Sounds awful, right
You don’t have to use Wave in this real-time way. It also works as a standard e-mail. What’s really different about Wave is that if you’re replying to a message and the person you’re replying to happen to be online, they can jump into the conversation at that point, and change what is an e-mail conversation into an instant message conversation or a chat.

A. It makes people see each other online.
B. It enables people to send real-time e-mails.
C. It allows you to send more e-mails at the same time.
D. It can be easily connected to other communication systems.
