Answer:
The word "they" may refer to a gender-specific pronoun, or it may refer to a person describing another. The word "it" may refer to a thing, animal, etc.
Explanation:
When describing a person, you do not use the word it. This is because a person, unlike a dog or a cat, can be easily identified by gender or name. Another animal may not show specific traits that define its gender, and they may not possess the ability to verbalize; in this circumstance, you would refer to the creature (or object) as "it".
Answer:
Form
Explanation:
It isn't theme. Theme is the message of a passage or text. (Not to be confused with main idea, which is the the overall point the passage or text was written. ) It isn't figurative language, because that is a whole <em>type </em>of writing structure. (For example, instead of saying, "She felt sick and dizzy," you could use figurative language and say, "Her legs felt like cooked spaghetti noodles and her stomach started doing somersaults." Heck, it's a little crazy, but it makes the writing better. Lastly, it isn't plot, since plot is pretty much what <em>happens</em> in the story. I would call it conflict, but it isn't always problems. Maybe a girl finds her long-lost father. That would be part of the plot but not conflict. (Well, I guess it <em>could</em> cause some conflict if you think about it.
So, long story short, the answer is form.
Sentence option two is an incorrect sentence. It used “theirself” instead of themself, which is not a word.
