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)
The answer is b. silent support allows a person to think for themselves and not go off of another person's feelings. It increases their individuality
The answer to the question is B
There are multiple ways of comparing and contrasting structures that each have different implications and dangers.
1. The back-and-forth method, in which every other sentence compares and contrasts. ie:
P1- theme
-p1 Book A is blah, whereas Book B is blah.
P2- theme
-p2 Book A is blah.... you get the point,
The danger of this method is sounding too redundant, although it does a good job of focusing on the themes.
2. The separate, mixed theme method, in which an entire paragraph is dedicated to each subject, but the themes are thus mixed up within those paragraphs. This method is less redundant but runs the risk of losing clarity of theme.
3. The compare vs. contrast method. This one is fairly straightforward: A paragraph comparing, a paragraph contrasting, and one of synthesis at the end. The pros: It's playing it safe, and it'll work. The cons: It's boring.
Combinations of these 3 methods work as well, it all depends on your personal writing style and the subjects you're comparing.
Good luck
