But e-ticketing adds a new opportunity that not only brings savings but convenience as well, since it allows visitors to avoid the line at the gate."If you can get in early before the lines fill up, you’re getting more for your money," says Robert Niles of the website Theme Park Insider. Why do more and more theme parks offer large discounts off the gate price ？（）

A. To get in line at the parks this summer.
B. To encourage more people to come to the parks.
C. To enable people to get e-tickets at home.
D. To reduce the attendance figure.
