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.
With the development of spread-spectrum technique, we may use Bluetooth connection as a substitute for cell phone.

选项 A、Y
B、N
C、NG

答案C

解析 本题定位信息是spread-spectrum,从而锁定Bluetooth Operation部分。该部分只是在第四段最后一句提到了与手机相关的信息,This same technique minimizes the risk that portable phones or baby monitors will disrupt Bluetooth devices,但是并未提到题干中所说的“随着扩展频谱技术的发展,我们可以用蓝牙技术来代替手机的应用”。题干表述在文中找不到依据,因此答案为NG。
