Answer:
1. Things from television aren't always what they seem.
For example, when Brian got into a plane crash he had gotten false hope that someone would find him within 1 to 2 days. He got these beliefs from the news. This was proven as a false reality a few days later when Brian realized that it might take a long time to find him.
2. Positivity is something someone needs to help in bleak situations.
For example, Brian thought back to when he was in school he thought to when he was with his teacher Mr. Perpich. And his point of view for the situation changed for the better.
3. You won't realize how lucky you are for what you have until it's gone.
For example, when Brian was stranded he kept on thinking back to the thought that he had nothing. The word nothing kept ringing in his head. He thought of how hungry he was from time to time and kept trying to ignore the disastrous situation at hand.
Sorry for taking a long time to write this.
Hope this helped! :)
Answer: I would contend that the right answer is the B) Players often return to a game after a head injury—they.
Explanation: By using a dash or specifically an "em-dash" ( — ) at the end of the sentence, the writer is clarifying or amplifying the information that he or she has already provided (that players often return to a game after a head injury). Options C and D are grammatically incorrect, so they should be discarded. Furthermore, since the two sentences ("players..." and "they do not want...") are not independent, the use of a semicolon (option A) should also be discarded.
