Teacher: Based on the information present in the given passage, you need to write a correct answer to the given question. A correct answer is one that correctly and completely answers the question. Do not write answers that address the question partially or incorrectly. The correct answer must be contained in the given paragraph.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Paragraph- Sent 1: Obama was born on August 4, 1961, at Kapiolani Maternity & Gynecological Hospital in Honolulu, Hawaii.
Sent 2: He is the only President to have been born in Hawaii.
Sent 3: He was born to a white mother and a black father.
Sent 4: His mother, Ann Dunham (1942-1995), was born in Wichita, Kansas, of mostly English descent, with some German, Irish, Scottish, Swiss, and Welsh ancestry. Question: How old was Obama's mother when he was born?
Solution: 19.
Reason: Obama was born in 1961. His mother was born in 1942 and 1961-1942=19. Therefore, any of the following responses are considred correct: '19' and 'almost twenty'.

Now, solve this instance: Paragraph- Sent 1: The highest point of a wave is the crest.
Sent 2: The lowest point is the trough.
Sent 3: The vertical distance between a crest and a trough is the height of the wave.
Sent 4: Wave height is also called amplitude.
Sent 5: The horizontal distance between two crests is the wavelength.
Sent 6: Both amplitude and wavelength are measures of wave size.
Sent 7: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows.
Sent 8: The greater each of these factors is, the bigger a wave will be.
Sent 9: Some of the biggest waves occur with hurricanes.
Sent 10: A hurricane is a storm that forms over the ocean.
Sent 11: Its winds may blow more than 150 miles per hour!
Sent 12: The winds also travel over long distances and may last for many days.
Question: How do you calculate the height of a wave?.
Student:
Vertical distance between a crest and a trough.
