阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。
In the aftermath of the terrorist attacks on the World TradeCenter, security experts are trying to develop new ways of rescuing people from burning skyscrapers. One idea is a platform capable of flying vertically and hovering in the air like a helicopter. The platform would rise up and down alongside a skyscraper and pick up people trapped in high stories.
The idea for the vertical takeoff platform was hatched more than ten years ago by a Russian aerospace engineer,David Metreveli, who has since moved to Israel. Metreveli’s design, called theEagle, calls for two jet engines that turn four large horizontal propellers. The spinning of the propellers generates the necessary lift, or upward force, to raise the platform. The more power is supplied to the propellers, the higher the platform rises. Moving the platform sideways involves applying differing amounts of power to each propeller.
Helicopters are now used in some cases to get people out of burning buildings.Escape baskets slung from them dangle beside the building for people to climb into. Unfortunately, the baskets cannot reach every floor of a building because the ropes from which they hang become unstable beyond a certain length.
So far, Metreveli has built a small-scale model of theEagle to test his ideA、In the wake of September 11, he has been able to secure enough funding to start building a larger, 4-meter by 4- meter prototype, which he calls theEaglet.

从上下文看，本段介绍直升机在营救高楼受困人员时有不足之处，即救生篮晃动，不稳定。虽然本段没有明说，读者能体会到，the Eagle就没有这个缺点。所以，本题说helicopter就是the Eagle，传达的信息是错误的。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
