Hi there!
The sentence that would need a semicolon is the first sentence, Jerry loves tennis he plays everyday. Here's the corrected sentence: Jerry loves tennis; he plays everyday. The semicolon separates the two ideas in this sentence. Since this is the only sentence that has two ideas in it, this sentence needs a semicolon. (I hope this explanation is okay, and you understand what I'm trying to say!)
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

No we, I, us, etc.
Well, unregulated power can lead to greed and zero mercy for those within your peasant realm. Great unhealthy amounts of cruelty, and etc.
"Unchangeable truth" is something that must be accepted; it must be faced in order to be conquered. Whether it is a prejudice someone holds against you, or a mistake you made in the past, you must be willing to address it in order to change it. The truth cannot be denied, but it can be changed. Hope this helps!
