阅读下面短文，根据要求完成下列各题。

The K-Cup is a great invention. We can see the product everywhere in the world. However, its inventor, John Sylvan, said in an interview, “I feel bad sometimes that I ever did it.”

Why? Because it’s bad for the environment. K-Cups are almost impossible to recycle. John Sylvan couldn’t do much about the problem. He sold the invention to Keurig Green Mountain for ＄50,000 in 1997. Keurig Green Mountain made ＄4.7 billion last year. Much of that money came thanks to K-Cups.

“I’ve told them how to improve the K-Cup, but they don’t listen,” said John Sylvan. Sylvan has found solutions, like reusable K-Cups. He said he even tested his design years ago, and it worked.

However, Keurig Green Mountain refused John Sylvan’s advice. The company said that it had a plan of its own and that it would make 100% of K-Cup packs recyclable by 2020.
