There is only one sentence that begins with an interrogative word (e.g. Who, What, When, Where, Why, How) and ends with a question mark as its punctuation. This would be the last sentence, which is predicated upon the information from the previous sentences.

There is only one question in OP's picture and it is dependent upon the previous statements made prior to the question.

>What is the probability that the next ball you take from the same box will be gold?
Is dependent upon:
>It's a gold ball
Is dependent upon:
>You put your hand in and take A BALL from THAT BOX at random (emphasis is mine)
Is dependent upon:
>You pick a box at random.
Is dependent upon:
>One box contains 2 gold balls, another box contains 2 silver balls, and the final box contains one gold and one silver ball.

The above sentence dictates that there are three boxes so the above sentence is not dependent upon the statement "There are 3 boxes"

All of the information, except for the very first statement, is relevant to the only question asked in OP's picture.

>But you're picking boxes!
No, the question is picking boxes for you. If you pick the double silver box at random the question is never asked. Being that the question is picking boxes for you we only look at the boxes on the left.
