I have read ______ Shakespeare. Fill in the gap-

The correct choice in this context is "no article."

"I have read Shakespeare."

When mentioning the name of a famous person or a singular proper noun like "Shakespeare," generally no article is used. The absence of an article indicates that you are referring to the person in a general or unspecified way. In this case, "Shakespeare" is a specific and well-known name, and it doesn't require an article before it.

So, the sentence is correct without an article, and it would be: "I have read Shakespeare."
