Which sentence from Barrio Boy states the most reasonable inference and provides a valid clue to support it?

The passage says Ernesto and his mother will go to Tucson and wait there “until another pass and money could be obtained,” but it gives no date or length of time. It is reasonable to infer that Ernesto does not know how long they will stay. The other choices either draw conclusions the clues do not establish or misread who is confused about the sign.
