Click to correct the three capitalization errors. After a Blizzard dumped twelve inches of snow across the Northeast, the Brooklyn

I am confident that there are only TWO capitalization errors here. You might be fooled into thinking that the word 'Northeast' is the third error, but you would be wrong.

After a blizzard dumped twelve inches of snow across the Northeast, the Brooklyn  Bridge was closed to bike riders for three days.

Explanation:

The word 'Northeast' in this sentence refers to a region; therefore, it requires a capital letter. If the word referred to a compass direction instead, then a lowercase letter would be needed.

The rule is this:  Lowercase words like north, south, northeast, etc. when they indicate compass direction, but capitalize them when they indicate a region: the West Coast, for example.

Ex.  We drove northeast for five hours and still hadn't arrived at grandma's house.

themselves

an intensive pronoun is a pronoun that ends in self or selves, such as himself, herself, themselves, yourself, ourselves. since band members is a third person plural, the correct intensive pronoun would be themselves. if the band was talked about as a collective noun, itself would be the appropriate intensive pronoun. intensive pronouns are used to add emphasis to the noun it's modifying which is why it directly follows it.

jenkins wanted the narrator to write a ghost story for his magazine. he wanted the narrator to give the readers a story based on the supernatural. he wanted him to give the readers real 'horror' stories and not the type of live ghosts which he had presented in his earlier stories.
