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.
What can we learn about the greenhouse gas sensors according to Earth Networks?

选项 A、They can be connected directly into the weather sensor network.
B、They can be deployed quickly because everything is ready.
C、They can be used quickly for the existing 8 000 weather sensors.
D、They will become the largest greenhouse gas sensors in the world.

答案A

解析 推理判断题。题干问我们可以从Earth Networks公司那里知道哪些关于温室气体监测站的信息。定位段表明,EarthNetworks公司声称温室气体监测站将直接与气象监测站网络系统联网。并且由于EarthNetworks公司基础设施已经部署完备,温室气体监测站很快就会部署好。故A)“它们会直接与气象监测站网络系统联网”与文意相符。
