Sure! Here is a detailed, step-by-step answer to the questions based on the given letter and task:

1. Who writes the email?
The email is written by Susan, as indicated by the email address "Susan@mail.uk" in the "From" field.

2. What are the questions you have to answer?
The task asks you to write a message to Susan that answers her three questions, which are:

• What do you do on Sunday if the weather is good?
• What do you do on weekends?
• When do you prefer to do your homework, and why?

3. How many words can you write?
You are instructed to write between 100 and 120 words for your reply.

4. How will you start your email?
You should begin your email with a polite greeting, such as:

• "Dear Susan,"
  or simply
• "Hi Susan,"

It depends on how formal or informal you want the tone to be. Since the original message appears casual, a simple "Hi Susan," would be appropriate.
