Answer:
The first one is a run on sentence.
Explanation:
There are multiple pieces of information in the sentence that should be separated by a comma but aren't, so the sentence is run-on.
The correct sentence is c) Sitting behind the tall stone walls, the soldier used a periscope to view the field surrounding the fort.
A periscope (a tube with a set of mirrors) is an apparatus with which we can see things on a surface if we are submerged (for example, in a submarine) or if there is a tall obstacle in front of us, like in this example, we can use a periscope to see things which would otherwise be impossible to see.
The last sentence that starts with "Today.." gives the reader the sense of mood and emphases death with black and white. I hope this helped.
B. qtd. in
Let's say you were using an article from ESPN to write about the NCAA tournament. Coach Pitino is quoted as saying, "The tournament is rigged." If you only want to use Coach Pitino's quote, you need to use the indicator "qtd. in" as part of your citation since Bilas, the author of the article you are reading, did not actually say those lines himself. Pitino is being quoted in the article by Bilas. After the quote you would write (qtd. in Bilas).
I’m pretty sure the answer would be D.
