Refer to the exhibit. Asymmetric broadband service with significantly greater downstream bandwidth is recommended for Teleworker deployment. Which reason is the most accurate?（）https://assets.asklib.com/images/image2/2018080114044968996.jpg
A . Most ISPs do not provide QoS for residential broadband. Asymmetric bandwidth reduces the chance of downstream congestion when traffic from Internet sites competes for bandwidth with IP voice traffic.
B . Additional downstream bandwidth compensates for insufficient upstream bandwidth. The aggregate bandwidth provides the same result.
C . The additional bandwidth is needed to access more than one site. Most HTTP traffic is downstream.
D . The additional downstream bandwidth allows the Enterprise VPN device to send the IP voice packets much faster, allowing them to reach the Teleworker network with less latency.

Renewable energy sources can be replenished in a short period of time. The five renewable sources used most often include hydropower (water), solar, wind, geothermal, and biomass. Renewable energy's impact on the world's energy picture is significant. Many important events have occurred during the history of using renewable sources to generate electricity--but the overall consumption from renewable energy sources has declined by about 15 percent from their I996 peak to about 6 quads in 2005.
The use of renewable energy is not new. Five generations (125 years) ago, wood supplied up to 90 percent of our energy needs. Due to the convenience and low prices of fossil fuels, wood use has fallen. Now, the biomass which would normally present a disposal problem is converted into electricity (e.g., manufacturing wastes, rice hulls, and black liquor from paper production).
Historically, low fossil fuel prices, especially for natural gas, have made growth difficult for renewable fuels. The deregulation and restructuring of the electric power industry could have a major impact on renewable energy consumption. Demands for cheaper power in the short term would likely decrease demand for renewable energy, while preferences for renewables included in some versions of proposed electricity restructuring legislation would breathe new life into this industry.
Use of renewables in the United States is not currently expected to approach that of the major fuels, and due to their limitatious (e.g., their intermittent nature-cloudy days have no solar gain, quiet days mean no wind blows to drive wind turbines, dams are primarily for flood control, so hydroelectricity production varies as dams' water levels change), renewables may never provide "the" answer to all energy problems. Around the world, renewable energy is proving to be of great value.
In 2005, about 6.1 Quadrillion Btu (Quads) of U.S. energy came from renewable fuels. Each of the energy sources we use is measured, purchased, and sold in a different form. Many units of measurement are used to measure the energy we use each day.
From 1996 to 2005, the trend of the consumption from renewable energy was ______.
A．increasing
B．decreasing
C．irregular
D．not mentioned

The medical world is gradually realizing that the quality of the environment in hospitals may play a significant role in the process of recovery from illness. As part of a nation-wide effort in Britain to bring art out the galleries and into public places, some of the country's most talented artists have called in to transform. older hospitals and to soften the hard edges of modern buildings. Of the 2 500 National health Service hospitals in Britain, almost 100 now have significant collections of contemporary art in corridors, waiting areas and treatment rooms.
These recent initiatives owe a great deal to one artist, Peter Senior, who set up his studio at a Manchester hospital in north-eastern England.
The quality of the environment may reduce the need for expensive drugs when a patient is recovering form. an illness. A study has shown that patients who had a view on to a garden needed half the number of strong pain killers compared with patients who had no view at all or only a brick wall to look at during the early 1970s. he felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience.
A typical hospital waiting room might have as many as 5 000 visitors each week. What better place to hold regular exhibitions of art？ Senior held the first exhibition of his own paintings in the out-patients' waiting area of the Manchester royal Infirmary in 1975. Believed to be Britain's first hospital-artist, Senior was so much in demand that he was soon joined by a team of six young art school graduates.
The effect is striking. Instead of the familiar long, barren corridors and dull waiting rooms, the visitors experience a full view of fresh colours, playful images and restful courtyards.
Compared with the total number of Britain's National Health Service hospitals, the hospitals which have art collections is only ______.
A．4%
B．40%
C．25%
D．50%.
