Is and are

[Rachel Adams]

I have two questions regarding these sentences.

Is it wrong to use "are" in #1 because of "this"? If I changed it into "these are John and Amanda" it would be correct, I think. And in the second sentence isn't it wrong to use "is"? Can John and Amanda be considered as one in the second example too?

1. "This is John and Amanda."

2. "John and I are from London."

Yes.

It's wrong to use "is" there.

1. "This is John and Amanda."

2. "John and I are from London."
