1. Seldom more than 40 feet wide and 12 feet deep, but it ran 363 miles across the rugged wilderness of upstate New York, the Erie Canal connected

5. The Erie Canal, seldom more than 40 feet wide and 12 feet deep, but running 363 miles across the rugged wilderness of upstate New York, connecting

我覺得OG對於D的解釋有點怪

(D)the paired concepts of width and depth should be joined by "and", nor or.....這句的意思是說，D錯的原因之一是因為more than 40 feet wide or 12 feet deep嘛?若是做此解釋，則正確答案B也是用or阿

不曉得是不是我誤解了OG的意思，還請大牛們多多指教!!
