Step-by-step explanation:
A cyclone hit the coast of Odisha, destroyed homes and flooded roads. The people of
the region are living in a Red Cross Camp as they have lost all their belongings in the
cyclone. You are the Secretary of the Social Service Club in your school and would like
volunteers to collect clothes and medicines from people's homes for the Club to send to
the Red Cross Camp. Write a notice, in not more than 50 words, mentioning the details
of when, where and at what time the collection will take place.
