The answer is:
D. When the narrator tells the story without any personal bias, the reader gets an objective view of the situation
The correct answer is "I can't believe he has <em>swum </em>to the island." Swum is the past principle of "swim." However, if you drop the word <em>has </em>the answer would be D and the sentence would appear much more grammatically appealing. :)
Answer: The correct spelling is “We passed the vehicle because the driver was moving very slow.”
Hope that helped :)
If this is a question in a USA TP test than the answer is D. cast out
Hope I could help!
