A woman is holding her child while a man is reading something from a piece of paper and taking something from a bowl that a younger girl is holding in a park with a small lake in the background.
There are people outside
A park with a small lake is a place typically found outside.
The woman, child, man and younger girl are all people and thus can be described collectively as 'people', also the fact they're in a park indicates they are outside.
If there is a lake in the background of where they are, they are outside.
