Teacher:In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
Teacher: Now, understand the problem? Solve this instance: passage: The effects of high altitude on humans are considerable. The percentage oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 m (7,000 feet) above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. Athletes use these adaptations to help their performance. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 metres (26,000 ft) as the ''death zone'', where it is generally believed that no human body can acclimatize.
question: is it hard to breathe at 7000 feet?
Student:
Yes
