"To get to the grocery store, walk or drive north on Main Street."
Explanation:
You don't need to capitalize the north when you are being directed somewhere. As for the Main Street, since that's the actual name of the street, you would capitalize both parts.
To get to the grocery store, walk or drive <u>north on Main Street</u>
Explanation:
In the sentence, “north” should not be capitalized because it acts as an adverb that indicate direction. However, when this word acts as a noun that refers to specific regions or are part of a name (e.g.: “in the North” and “the North Coast”), it should be capitalized. As for the word “on,” it is a preposition, and prepositions are never to be capitalized. Lastly, “Main Street” is a proper noun, that is, a noun that names an specific thing or person, and as all proper nouns, it should be capitalized.
the third one, if you add the comma without the when then you would have a comma splice (when you put a comma between 2 independent clauses without a conjunction) adding the when before Cynthia makes the first part a dependent variable and makes it okay to add the comma!
