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).

Input: Consider Input: Paragraph: Shorter wavelengths (higher frequencies) correspond to higher energies and thus hotter star temperatures.
 Question: Sue sees a star with a high frequency. Erin sees a star with a low frequency. The hotter star belongs to 
 Choices: A)Sue 
B)Erin

Output: Sue


Input: Consider Input: Paragraph: By using multiple stages, empty fuel containers could drop away. This reduced the mass of the rocket so that it could fly higher.
 Question: David is getting ready to fly into space on a rocket. As the rocket shoots upwards, part of the mass falls away, allowing the rocket to go 
 Choices: A)higher 
B)lower

Output: higher


Input: Consider Input: 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
Output: the rocket with highest gas velocity
