The young child could refer to a child of either gender, not just a boy.  The fact that he is blowing up an orange balloon does not imply that the boy gets ready for his birthday party, he could easily be preparing for another event.


Context: A young child, wearing a blue shirt and green hat, is blowing up an orange balloon.
Hypothesis: A boy gets ready for his birthday party by blowing up balloons

Given this context, is the hypothesis true (Yes/No/I don't know)?
