Teacher: You are given a short paragraph, a question and two choices to answer from. Choose the correct answer based on the paragraph and write the answer(not the key).
Teacher: Now, understand the problem? If you are still confused, see the following example:
Paragraph: Many of the worlds people live with water scarcity, and that percentage will increase as populations increase and climate changes.
 Question: John's town used to have lots of water, back when there were only a few hundred people. However, now that the town holds several thousand people, the water availability is 
 Choices: A)scarce 
B)plentiful
Solution: scarce
Reason: Based on the information given in the paragraph, population growth will make water more scarce, so that is the correct answer.

Now, solve this instance: Paragraph: The rocket goes upwards because the hot gases shoot downwards out of the nozzle. The faster the gases go downwards, the faster the rocket goes upwards.
 Question: Boris was tasked with developing a hypersonic rocket. He built two prototypes that were identical except that they have different gas velocities out of the nozzle. Which rocket was likely the fastest? 
 Choices: A)the rocket with highest gas velocity 
B)the rocket with lowest gas velocity
Student:
the rocket with highest gas velocity
