Hello Bluekola888,
Nice to meet you!
Your questions: What skill is "critical" to success in online learning?
Your answer: Skills needed for online learning would be computer literacy, you have to be an active learner, you have to be good in reading and writing. But the most critical that I BELIEVE are CRITICAL is having time commitment and being self motivated.
Thanks for your time and have a great day!

#1 would be the answer because the sentence would not be able to stand alone.
The correct answer is 3) The narrator has been insulted many times and vows revenge against Fortunato.
At one point in time when he felt that he had been insulted, the narrator decided that enough was enough and that he would have his revenge.
It does not really matter which form you write in. However, writing in the third person omniscient is generally more effective for essays. If you were writing, say, a blog, you would use the first person, but in this case, I think you want to use the third person.
B. Across the street is the prepositional phrase
