In this task, the input is a set of dialogues between a user and an assistant. You need to find the dialogue that is basically a response given to a question or an aspect of the user.
One example: Hi. I want information about Namibia.
Nmbia is a country in southern Africa.
Do you have information about the media there?
What about it?
Interesting! What can you tell me about the politics and government?
Solution is here: Nmbia is a country in southern Africa.
Explanation: This is a good example. The output is the response to the question asked by the user.

Now, solve this: I'm happy to have helped you today.
That's probably correct. What can you tell me about their society?
Really? How can they be called Cape Verdeans if they live in another country? They moved out of Cape Verde?
They still maintain their citizenship for their home country.
Sorry, I can't find that information for you, but an interesting fact is that more Cape Verdeans live in other countries than they do in their own. There are many communities in the US, totaling around 500,000 people. Most of those live in New England.
Solution:
They still maintain their citizenship for their home country.
