What is the prompt of the essay?
Essentially a thesis statement should state your opinion/the main idea of your essay. If a thesis is a question, it is no longer a statement.
Depending on what you will be writing about here are some alternatives that are close to your original thesis:
Social media has negative/positive effects on young adults. (discuss positive or negative effects)
Social media can affect young adults in a variety of ways. (discuss both positive and negative effects)
Young adults are affected by social media in many positive/negative ways. (discuss positive or negative effects)
Division is where you have a sertain about of (for example) money, and you have to split it up equally with four people. So yes basically.
Well, you're going to talk about the conflicts in The Lottery and The Lady or the Tiger... So... in The Lottery, the main conflict was that the lady (whatever her name was) was chosen to be stoned in the lottery. It wasn't really resolved in anyway, except that she got.. stoned. I haven't read The Lady or the Tiger, but you would do the same thing for that. Then you would state the theme, or moral, or main point, of each story. And then you would compare how the resolutions for both conflicts demonstrate the stories' themes.. Does it make a bit more sense?
