Task: Question Generation
Input (English): Nanjing is the intersection of Yangtze River, an east-west water transport artery, and Nanjing–Beijing railway, a south-north land transport artery, hence the name “door of the east and west, throat of the south and north”. Furthermore, the west part of the Ningzhen range is in Nanjing; the Loong-like Zhong Mountain is curling in the east of the city; the tiger-like Stone Mountain is crouching in the west of the city, hence the name “the Zhong Mountain, a dragon curling, and the Stone Mountain, a tiger crouching”. Mr. Sun Yet-sen spoke highly of Nanjing in the “Constructive Scheme for Our Country”, “The position of Nanjing is wonderful since mountains, lakes and plains all integrated in it. It is hard to find another city like this.”
Output (English): What is the east-west waterway near Nanjing?
