Take a look at source 2. You won't have time to read the whole thing, but you can read the abstract to get an idea of what the source is about and then you can skim through the rest of the source to see what you notice about it. You can also look at the information about the source you see on this page. Use Google if you need to to find out more about the source.
Ask yourself what kind of source this is and how you know.
We'll discuss it together as a class.
