Answer:
Two of the letters in aunt Emily's package concern a request for Mother's consent.
Step-by-step explanation:
In most cases, a parent's consent is required for legal or important actions taken by a child.
This is because parents are legally responsible for their children's well-being and safety.
For example, a child cannot undergo a medical procedure without their parent's consent, nor can they marry without their parent's permission.
The letters in Aunt Emily's package are likely to be asking for Mother's consent for something important or sensitive.
This could be something like a child requesting permission to travel alone, to start a new job, or to move away from home.
While the other options, such as cooperation, approval, help, or advice, are all possible, they are not as specific and may not require the same level of parental involvement.
For example, a child might ask their mother for advice on a school project, but they would not necessarily need to get her consent to do the project.
Therefore, the most likely answer is "consent" because it is the most specific and commonly used word to describe a parent's approval for a child's actions.
