With this in mind, are the benefits of climbing Qomolangma worth the risks？__5__ A．For them, there are several reasons. B．Mount Qomolangma is the world's highest peak. C．It's a long climb to the top, but well worth the effort. D．The author lets the readers make decision by themselves. E．In addition, recent studies show there are some scientific reasons.
