A: What is your specialty?

B: My specialty is taking pictures.
B1: It is taking pictures.
B2: Taking pictures is my specialty.
B3: Taking pictures in it.
----------------------------------
Is this dialogue correct?
Are all answers are acceptable?

B3 is odd, even though I know you meant "is" instead of "in."

The first three are fine. you could have B3 be simply "Taking pictures."

e.g. Taking pictures is it. 'in' should be changed into 'is'. What about this one?

Thank you for your kind explanation.
I'd like to post another question.

Thank you for using the Jiskha Homework Help Forum again. Yes, on the last two!

I mean the floowing one.

e.g. Taking pictures is it.
Is this correct?

That's OK, but rather cumbersome. People would just leave off the words "is it."

How do u change a transitive verb into a intranstivie verb?

The dialogue is grammatically correct, but the answers provided by person B may vary in their acceptability depending on the context and intended meaning. Let's break down each response:

B1: "It is taking pictures."
This answer is grammatically correct and states clearly that taking pictures is person B's specialty.

B2: "Taking pictures is my specialty."
This answer is a straightforward and concise way of expressing person B's specialty.

B3: "Taking pictures in it."
This answer lacks clarity and context. Without more information, it is difficult to determine what "it" refers to. However, if "it" is a specific context or setting being referred to earlier in the conversation, this response could be acceptable.

In conclusion, while all the answers are grammatically correct, the acceptability of each response may depend on the specific context and intended meaning.
