问题 Bluetooth is changing small-area networking into a wireless and automatic connection with no need for user intervention and low need of transmission power.
One security mode offered by Bluetooth is that data may be exchanged freely among the devices Bluetooth users establish as______.
选项
答案trusted
解析 本题定位词是security mode，从而锁定Bluetooth Security部分。该部分第二段第二句提到：In almost all cases，Bluetooth users can establish“trusted devices”that can exchange data without asking permission。由此可知，只要蓝牙用户将一些设备设定为“可信任的”，就能实现数据的自由交换了，故本题应填入 trusted。
