What is the book or excerpt?
I'm pretty sure it's true, there might be a thing or 2 they missed the first time around
.org, .gov, .edu are usually the most reliable domains when it comes to dealing with english related assignments.
.org - means the website is from an organization, without the intention of selling commercial products.
.gov - is from the government so we know that this is reliable
and .edu is usually for university websites.
Hope this helped.
