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.
People can send you data without your permission because the Bluetooth connection is______.
选项
答案automatic
解析 本题定位词是send和without your permission，从而锁定Bluetooth Security部分。该部分第  一段最后一句提到：With Bluetooth，though，the automatic nature of the connection…is also a benefit to people looking to send you data without your permission。由此可知，是蓝牙连接技术的自动性方便了一些人不经允许就能发信息给你，故本题应填入automatic。
