Answer:
Imagine seeing the Sun shining for day and night! Midnight Sun is a real thing; the scientific term is Polar Day. It is the Sun when seen at midnight. Many Alaskans can see it regularly during the summer months around the Summer Solstice in June.
The Sun does not set for over 80 days at a time in Barrow, Alaska. If the weather is fair, people can see the sun for a full 24 hours. Many tourists travel to Alaska to view the Midnight Sun. Although many people find it interesting, some local people do not enjoy the summer days with long daylight hours.
Explanation: The report needs serious reorganization. It is unclear what the numbers are supposed to mean-- maybe the kind of correction needed, so I'll try to go by the numbers.
1. Do not capitalize 'thing.'
2. delete 'for them.'
3. If you are explaining Midnight Sun, define the event first then tell when it happens.
4. This sentence fragment needs to be connected to another sentence.
5. Avoid saying 'is seen' (passive voice) again. Rewrite in active voice. "People can see . . ."
6. This is a good introductory "hook." Move to the beginning of the report.
7. Connect this information to another sentence (3) where it makes sense.
8. Correct 'so' to the actual number of days found in research.
9. This is a fragment and repetitious. Eliminate it.
10. Capitalize 'It' and move the sentence. This belongs in the first paragraph.
11. Be consistent about capitalizing 'Midnight Sun.' Add a period.
12. Rewrite to make sense. Avoid sweeping generalities and absolutes (never).
13. This subordinate clause must be connected to another. It makes a good transition between the information about the tourists and the statement about the local people.
