Read the following passage and answer the questions- 

Sanjeev was a policeman, serving in the Katchall island of the Nicobar group of islands. He somehow managed to save himself, his wife and his baby daughter from the waves. But then he heard cries for help from the wife of John, the guesthouse cook. Sanjeev jumped into the water to rescue her, but they were both swept away. Thirteen year-old Meghna was swept away along with her parents and seventy-seven other people. She spent two days floating in the sea, holding on to a wooden door. Eleven times she saw relief helicopters overhead, but they did not see her. She was brought to the shore by a wave, and was found walking on the seashore in a daze. Almas Javed was ten years old. She was a student of Carmel Convent in Port Blair where her father had a petrol pump. Her mother Rahila’s home was in Nancowry island. The family had gone there to celebrate Christmas. When the tremors came early in the morning, the family was sleeping. Almas’s father saw the sea water recede. He understood that the water would come rushing back with great force. He woke everyone up and tried to rush them to a safer place. As they ran, her grandfather was hit on the head by something and he fell down. Her father rushed to help him. Then came the first giant wave that swept both of them away.
