This paragraph is so ordinary, you may say "what is wrong with this paragraph?" out loud. Truthfully, this paragraph is totally usual minus one thing. What is so unusual about this paragraph, you ask? Study it for a bit; it is obvious. You'll know if your notion is right if you study through a long sitting.
HINT: Once again, there are NO spelling or grammar mistakes anywhere in the paragraph. If there are, they aren't the unusual item.
HINT 2: On a test, this is the answer that often represents "None of the above".
So, with this said, can you figure out what is so unordinary about the paragraph? You may not feel entirely intelligent when you get it.
