Hi Sesha, Good question. ***Importantly you must use your logic for this type of question. In this case, I recommend ‘disagree’ with two clear points for the body paragraphs. For example, “I disagree that writing letters is no longer necessary in the modern communication age because official documents require real signatures and people deserve sincere letters with gifts.” Then in each paragraph I would describe these points and explain how electronic communication is not a replacement.
Keep up the good studies.
