Answer:
The word being used incorrectly is "advise". The correct form would be "advice":
Pauline Phillips was born in Iowa in 1918, studied journalism, and went on to be the voice behind "Dear Addy," a popular advice column that first appeared in 1956.
Step-by-step explanation:
The two words are very similar and refer to the same thing. However, "advise" is a verb, while "advice" is a noun. In the sentence we are analyzing here, "advice" is actually functioning as an adjective, modifying the noun "column". An advice column is a section typically found in newspapers and magazines. It consists of a reply offering advice to a reader who has sent in a question.
