Imagine you are Arif/Arifa living at 15/A Khatun Road, Chattogram. You recently visited an island badly hit by a cyclone and flood. You saw ruined houses, stranded families, and children suffering from lack of food and clean water. You have a friend named Nida living at 88/2 Bashundhara, Dhaka. Now prepare the following.

a. Write a personal letter to Nida describing your visit (include sender's address, date, salutation, body, and closing).

b. Write how you would fill the 'From' and 'To' addresses on the envelope.

c. Give five useful phrases or sentences (each 6–10 words) that describe the human suffering you witnessed and can be used in the letter.

d. Suggest three practical ways Nida (and her circle) can help the flood victims, with one sentence explanation for each.
