This article is very short, so first, please listen to the news article: Click here to listen

Questions:
1) Just from listening - what did you learn about the size of these monkeys?
2) What did the scientist suggest is the reason for the pause?
3) Do you know of any cases where primates have actually communicated with humans? Do you think it is really possible or is it just mimicking? Here is a great video of such a topic. I recommend watching from 5:15.

If you couldn't catch everything from listening, then please see the article here.
