单项选择题

Human reliance on information technology today is quickly becoming global. The
Line technological developments in the areas of computing, networking, and software
engineering have aided the transitions from paper to paperless transactions, and
text and data media to multimedia. Today, speed, efficiency, and accuracy in the
(5) exchange of information have become primary tools for increasing productivity
and innovation. Activities as diverse as health care, education, and manufacturing
have come to depend on the generation, storage, and transmission of electronic
information. Computers are not only used extensively to perform the industrial and
economic functions of society but are also used to provide many services upon which
(10) human life depends. Medical treatment, air traffic control, and national security are
a few examples. Even a small glitch in the operation of these systems can put human
lives in danger. Computers are also used to store confidential data of a political,
social, economic, or personal nature. This fairly recent and progressive dependence
on computer technology signals a real danger for the human race.
(15) Current computer systems offer new opportunities for lawbreaking and
the potential to commit traditional types of crimes in nontraditional ways. For
example, the threat of identity theft is magnified by our reliance on computers to
assist us in everyday activities such as shopping and paying bills. Identity theft
refers to all types of crime in which someone wrongfully obtains and uses another
(20) person’s personal data by way of fraud or deception, typically for economic gain.
By making personal and credit information available on the Internet, people open
themselves up to the possibility of a criminal obtaining this information and
using it for nefarious purposes. This is but one instance of the negative impact
that overreliance on computer technology can have on society.
(25) As humans continue to make technological advances, so too do they rely
more heavily upon those innovations. This is a dangerous progression that must
be tempered with common sense and self-restraint. We cannot allow computer
technology to control too many aspects of our lives, lest we become victims of our
own ingenuity.
The author most likely uses the phrase "a small glitch" (line 11) in order to（）

A．acknowledge the fact that human reliance on computer technology is completely safe
B．emphasize the idea that it is dangerous for humans to rely so heavily on computer technology
C．cast doubt on the accuracy of any personal data collected on the Internet by criminals
D．criticize human technological advances in the areas of education, medicine, and national security
E． disprove the theory that computer technology is unnecessary for human advancement
