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 本题定位词是spread-spectrum，也需锁定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，而并未捉到题干中所说的“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。
