Read this excerpt from “Educate Yourself” by Marcus Garvey.

Your language being English you should study the English language thoroughly. To know the English language thoroughly you ought to be acquainted with Latin, because most of the English words are of Latin origin. It is also advisable that you know the French language because most of the books that you read in English carry Latin and French phrases and words. There is no use reading a page or paragraph of a book or even a sentence without understanding it.

In this excerpt, the author uses persuasive speech to

convince readers that Latin is better than English.
encourage readers to study both Latin and French.
argue that it is best to read foreign-language books.
persuade customers to buy a French dictionary
