Task: Question Generation
Input (English): Context: This room , where explorers first came looking for possible fall - out shelters during the Cold War , is one hundred feet from floor to ceiling . It is 130 feet from on wall to the other , front to back , and then 150 feet from side to side . If that does n't give you perspective , this room is about as tall as a ten story building . This ledge is up at the TOP of the big damn room . There is no way to get up to it , except from the bottom floor , crawling over piles of broken rock and stalagtites , and scaling an almost vertical wall . Its hard to think about this person crawling through this cave , and scaling this wall with a simple wooden torch . So I tried to ask the guide about it .
Output (English): Why was he so impressed by the room ?
