Hope that helped!
This could be answered, theoretically, in many different ways. All of which might sound a bit dirty. The translation of the sentence is: "What ___ ___ (to) do to Juan on vacation?" I could fill in the blanks with "tú quieres" which would translate the sentence to "What do you want to do to Juan on vacation?" Without choices, that is the best I got.
In English: Select the sentence that expresses a hope. It is necessary that you ride your bike to be fit. It is important that the train leaves on time. I hope the paramedics help them as soon as possible. I recommend that you buy some stamps to send letters.
