回答下列问题：

已知函数f（x）=$\left\{\begin{array}{c}\left|{\log }_{2}x\right|,0<x<2\\ \cos \left(\frac{\mathrm{\pi }}{2}-\frac{\mathrm{\pi }}{4}x\right),2\le x\le 10\end{array}\right.$，若存在实数x₁，x₂，x₃，x₄满足x₁＜x₂＜x₃＜x₄，且f（x₁）=f（x₂）=f（x₃）=f（x₄），则x₁x₂（x₃﹣1）（x₄﹣1）的取值范围是（　　）

    I am interesting in spiders (蜘蛛), so this summer I watched them for quite long lime. Spiders don't look beautifully, but they have their own way of killing flying insects. They often build “bridges” between branch. They climb up a branch slowly, pulling some silk. Then they pull the silk towards another branch. When they built many “bridges”, they begin to form webs. As long as insects happen to touch the webs, no matter what hard they try, they can't escape. One day, there was a stronger wind, and the webs were broken, but the spiders still went on to building their “bridges”. They are not afraid with difficulties. As students, we should learn from it.
