问题 Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient—no matter where he or she may be.
Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological (生理的) data from the actual patient. A group from the University of Kentucky has shown that by using an off-the-shelf (现成的) PDA (personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient’s vital signs over the telephone. With this kind of equipment in a first-aid kit (急救包), the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response—especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise.
But there is one problem. Bandwidth is the limiting factor for transmitting medical images a-round the world—CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation Internet and the third-generation mobile phones for the future of distributed medical intelligence.
Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in (迎来) an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common. [br] The word "problem" in the fourth paragraph refers to the fact that______.

选项 A、there are not enough mobile phones for distributing medical intelligence
B、CT scans are one of the biggest bandwidth consumers
C、bandwidth is not adequate to transmit complex medical images around the world
D、communications satellites can only cope with the short-term needs during disasters

答案 C

解析本题是一道推断词汇含义题。问第四段中problem一词指的是哪个事实。第四段第一句提到的问题实际上指本段第二句表达的内容。该句可以理解为：带宽是制约着在全球范围内传送医用图像的一个因素一一CT扫描图像是最大的带宽使用者之一。言外之意，由于全球范围内计算机网络尚未普遍采用带宽传输数据，致使CT扫描图像无法传送。因此，本题的正确答案应是C“带宽不足以在全球范围内传送复杂的医用图像”。A“没有足够的移动电话传输医疗信息”。文章第四段最后一句话指出，医学正期待着第二代因特网和第三代移动电话的诞生，以便将来能传输医疗信息。D“灾难发生时，通讯卫星只能满足短期需要”。第四段第三句指出，当像地震、战争或饥荒这样的灾难发生时，通讯卫星能够满足短期需要。选择项D似乎与原文一致，但这句话表达的并不是“问题”的所在。本段第二句表达的才是现存的问题。
