Final answer:
To identify Daniella's main purpose for writing a letter to Carlos, look for explicit mentions of events or topics like going camping, missing him at home, expressing her feelings, or wanting to meet his college roommate.
Step-by-step explanation:
Without access to Daniella's letter or additional context provided by the question, it is impossible to definitively identify her main purpose for writing the letter. Therefore, I cannot confidently circle the correct answer.
However, I can explain the kind of information you would need to look for in the text to choose the right answer. If Daniella explicitly invites Carlos to go camping with their friend Marcie or mentions that she misses him at home during the holidays, then either of those options could be correct. If the letter focuses on expressing her personal feelings for Carlos, then she might be writing to tell him how much she cares. If she expresses a desire to meet Carlos's college roommate, then that could be her main purpose.
