Mark the letter A, B, C or D on your answer sheet to indicate the best arrangement of utterances or sentences to make a meaningful exchange or text in each of the following questions from 13 to 17.

1. It's taken decades for scientists to develop tasty food that astronauts can easily consume in space.
2. When astronauts get hungry, they simply rehydrate the food with water from a special dispenser and wait for 20 to 30 minutes until it's ready.
3. Much of this is freeze-dried; a process by which the food is cooked, frozen, and then it has all its water sucked out.
4. The food containers can then be attached to trays with fasteners to secure them.
5. Freeze-dried food lasts for a long time and doesn't need to be refrigerated, making it ideal for space travel.
