问题     The U. S. government dropped its court fight against Apple after it successfully pulled data from the iPhone of San Bernardino gunman Syed Farook, according to court records. The development on Monday effectively ended a six-week legal battle poised to shape digital privacy for years to come. Instead, Silicon Valley and Washington are poised to return to a cold war over the balance between privacy and law enforcement in the age of apps.
    "The government has now successfully accessed the data stored on Farook’s iPhone and therefore no longer requires the assistance from Apple Inc," the government said. It then asked the court to vacate a 16 February court order demanding Apple create software that weakened iPhone security settings to aid government investigators.
    On a conference call with reporters that the Department of Justice organized, a law enforcement official declined to offer details on the technique other than to say that it came from outside the government. The Guardian has reported that the technique used by the government has been classified.
    The official also declined to say if the government would share the technique which likely exploits a security glitch in the phone-with Apple. Doing so would presumably cause the company to patch the security flaw. This leaves the Justice Department with a difficult choice: make all iPhones more secure from other hackers and governments who know how to get inside, or preserve an investigative technique.
    Apple fought the February court order with a massive public relations and legal campaign. The company, America’s most valuable, argued that creating such software would force the company to betray its values along with the security and privacy of all of its customers.
Apple’s CEO Tim Cook argued that if Apple were forced to reengineer its products, it would open a Pandora’ s box that could give the government outsized control over how Silicon Valley makes its products.
    The case forced public leaders from Barack Obama to Bill Gates to declare where they stood on the balance between privacy and national security. It also kicked lawmakers into high gear to craft legislation governing a new generation of devices and messaging services that rely on strong encryption to protect user privacy.
    "It remains a priority for the government to ensure that law enforcement can obtain crucial digital information to protect national security and public safety, either with cooperation from relevant parties or through the court system when cooperation fails," Justice Department spokeswoman Melanie Newman said.  
The word "glitch" (Para. 4) is closest in meaning to

选项 A、effective mechanism.
B、sudden malfunction.
C、business vision.
D、faulty browsing.

答案B

解析 (1)根据题干关键词定位在第4段。(2)glitch的基本含义是指,a small problem or fault that stops sth working successfully。(3)根据文章,“官方拒绝透露,是否会与苹果公司分享这个技术”,“这一技术可能利用了一个苹果手机的……”(第4段:exploits,glitch)。“苹果公司可能会对这一技术缺陷进行修补”(第4段:patch the security flaw),flaw和glitch之间有照应关系。据此,确定选项[B]为最佳答案。
