问题
Heart disease takes up about ______ of the in-flight medical emergencies on US flights. [br] According to the passage, why does deep venous thrombosis usually happen?
选项
A、Because the economy class is not spacious enough.
B、Because there are too many economy-class passengers.
C、Because passengers are not allowed to walk during the flight.
D、Because the low pressure in the cabin prevents blood flowing smoothly.
答案
A
解析
第3段末句建议乘客有机会就多运动或伸展腿部,由此可以推断该段第2句中的cramped表明经济舱的空间狭窄,因此选项A为本题答案。选项B虽然是现实情况,但此项不能从原文推断得出,故不会成为本题的正确原因;第3段末句表明乘客可以离开座位走动,选项C与此矛盾;选项D与题干提到的病症没有直接联系。
