Final answer:
The passages provided do not contain information about Malú or her situation, so it's impossible to determine why she couldn't stay with her dad while her mom was away on a teaching job.
Step-by-step explanation:
The provided text passages do not give us any information about Malú or her family circumstances. Therefore, there is not enough context to answer why Malú couldn't stay with her dad while her mom took a 2-month teaching job in Chicago. We need specific information from the text that discusses Malú's situation to determine the reason. Since none of the provided passages reference Malú or her parents, the correct answer to the question is: d) The question does not provide enough information to answer.
