Which is correct?

Here are the address and possible ideas.

Here is the address and possible ideas.

Are

Here is the address and possible ideas.

Amr is incorrect.

There are two subjects here (address, ideas); therefore, the verb needs to be in plural form: are.

The correct sentence is:

"Here is the address and possible ideas."

To determine this, you need to consider the subject "address and possible ideas" in relation to the verb "is." In this case, "address and possible ideas" is a compound subject, which means it is treated as a single entity. Since the subject is plural, indicating more than one thing, the verb should be plural as well. However, the word "is" in the first option is singular, whereas the second option uses the plural form "are," which agrees with the subject. Therefore, the second option is the correct one.
