An example:

Pazardan ne aldýn?

Elma falan aldým.

What did you buy from the market?
I bought apples and such (no need to explain them all, its just clear you probably bought mainly fruits)

Ýstanbul´da neler gezdiniz?

Ýstiklal Caddesi´ni falan gezdik

What did you (sight)see in Ýstanbul?

We walked around Istiklal Caddesi and such (and all the other things that tourist generally go to see in istanbul, other touristic sights)

 Great examples! Thanks!
