Answer:
The family is on board a boat with limited supplies, and it is not certain when they will be rescued.
Step-by-step explanation:
Based on the dialogue in the story we can reach the conclusion that Ha and her family are actually aboard a boat with limited supplies.
For example, remember when we read,
"We are told to pack our crisscrossed packs and line up in a single file. Twenty at a time board a motorboat heading toward the dot."
This additional detail leads to the conclusion that the family is on board a boat with limited supplies.
