You would use a comma. The semi colon acts when both what is in front and behind it can stand alone as a sentence. “With technology in the hands of so many people” does not make sense standing alone.
sentence 3, there should be a comma after hugging.
I dont like your spelling but its ok we all have days like that :)
A.I stay up all night studying the words for the spelling bee. And you can see me any time of day practicing running. I never walk if I can trot, and shame on Raymond if he can’t keep up.B.But as they get to me, they slow down. I’m ready to fight, ‘cause like I said I don’t feature a whole lot of chit-chat, I much prefer to just knock you down right from the jump.C.I dig my sneaker into the grass and stare at Gretchen who’s staring back, we both wondering just who did win.<span>D.With a little more study I can beat Cynthia and her phony self at the spelling bee. And if I bugged my mother, I could get piano lessons and become a star.</span>
