Answer:
The sentence "The four ordinal directions are: northeast, southeast, southwest, and northwest." is punctuated correctly.
Step-by-step explanation:
The sentence "The four ordinal directions are: northeast, southeast, southwest, and northwest." is punctuated correctly because it uses a colon (:) to introduce the list of ordinal directions.
In this case, the colon indicates that what follows is a list of items that further explains or elaborates on the statement made before the colon.
It helps to separate the main clause ("The four ordinal directions are") from the list of directions, making the sentence clear and grammatically correct.
Hope this helps!
