They are the same, you could say either. In this case you could also say that you need to edit all of the odd numbered rows.

For 1, I would use 1c. The other sentences sound pretty unusual, at least in the United States. For 2, I would not use any of the examples. All of the sentences in 2 sound pretty unusual, at least in the United States. I would say = He was not half the coward that we took him for.

Hi, I'm Joey! I was found at the door of Kaide Mall. A woman, who's now my roommate, found me and took me home. She was so excited to have me in her life, whereas I felt so restless since I had no idea if she would cook me dinner! But so far so good. She told her friends the news and asked them to give me a name, and since she was not sure if I'm a boy or a girl (how stupid), she decided to call me Joey, which would always work. I'd like to keep a journal of my first days in here. Any kind of advice about how to please me is needed! Goodnight! ~MEOW~ I made a few changes. I couldn't find a way to make the corrections stand out, but you can compare it against the original in order to find them, which could also help you think about the corrections.

I can't say whether it's good or bad. It's relatively common. You can spell it "Carol" or "Carole". You could search for something like "people named Carol" or "people named "Carole" and find pictures of people with that name if you want to know more.

"Prep school" means "preparatory school". It's high school basically, but it's typically pretty expensive and sometimes the students live there, kind of like the school in Harry Potter. At least that's the meaning in the United States. College is where people can study after the mandatory primary and secondary schools. Each lap is a trip across the pool. You can also do laps around a track, et cetera.

When I was a child, I used to play with my friends a lot. Usually, we would play football or ride our bicycles to the park. I also remember having a best friend who happened to have a video game console and we would spend hours playing together at his place. Overall, I believe it was an ordinary yet somewhat blissful childhood. Through the years, I have lost contact with all my childhood friends.

My favorite subject is science.

In the United States, we don't say "humorous" very much, we usually say "funny". They're not the same, I would say that "humorous" means "funny" and "hilarious" means "really funny".
