问题     A private company announced Wednesday that it’s launching its own greenhouse gas measuring network to supplement governmental and academic efforts that have tracked greenhouse emissions for decades.
    Carbon dioxide—the greenhouse gas deemed most responsible for global warming—has been continuously measured in the Earth’s atmosphere since 1958. The measurements have been overseen by the federal government’s National Oceanographic and Atmospheric Administration (NOAA) and the Scripps Institution of Oceanography.
    The new sensor network will be overseen in a joint venture between Washington, D. C.-based Earth Networks, formerly AWS Convergence Technologies, and Scripps. Earth Networks is parent company of the popular WeatherBug weather network and computer application used by consumers, schools, government agencies and TV stations.
    "We have the largest network of weather sensors in the world," says Robert Marshall, CEO and founder of Earth Networks. Marshall says the new sensors will piggyback (借助) on some of the company’s existing 8 000 weather sensors.
    The greenhouse gas sensors will be networked directly into the weather sensor network, Earth Networks says. Because the Earth Networks infrastructure is already deployed, the greenhouse sensors can be deployed quickly.
    Marshall says the network will be devoted to measuring carbon dioxide, methane (甲烷) and other greenhouse gases. Over the next two years, it will consist of 100 sensors worldwide: 50 in the US, 25 in western Europe and 25 in the rest of the world.
    The company will invest $ 25 million over the next five years to deploy and operate the network.
    Earth Networks, in Germantown, Md., is working closely with scientists from Scripps, since Scripps deployed the first carbon dioxide sensor more than a half century ago—in 1958, at the Mauna Loa volcano in Hawaii. That remains the longest continuous record of atmospheric concentrations (浓度) of carbon dioxide in the world.
    The announcement was made Wednesday at Scripps in La Jolla, Calif. , where the first new sensor was deployed. A second will be deployed soon in Washington, D.C.
Why does a company launch its own greenhouse gas measuring network?

选项 A、This company wants to take its responsibility.
B、This company tries to measure greenhouse gas in the atmosphere.
C、The government and academic institutions ask the company to do so.
D、This company intends to add its efforts to monitoring greenhouse gas.

答案D

解析 细节推断题。题干问一家私企启动自己的温室气体监测网络系统的目的。由第一段可知,目的是要作为政府和学术界数十年来对温室气体排放监测的一种补充。由此可知D)“公司打算为温室气体监测增加自己的一份努力”为正确答案。
