That last word is a typo.
You're welcome.
Interesting post, but I found some typos:
Lets suppose, for the purposes of this post,
"Lets" should be changed to "Let's."
Whats actually going on here. We have three hypothesis.
"Whats" should be changed to "What's," at the very least. Additionally, these sentences seem off. The first one is a fragment, and it seems like they should be joined somehow.
We have three hypothesis.
Use the plural form here.
Option 2)
Did you intend to write a full sentence here?
Was there supposed to be more text here?
