He39。s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a colorcoded map showing where plants were running fevers. Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley39。s vibrations 23 . The smart buildings discussed in the passage __________.

A) Neutral B) Critical C) Objective D) Compromising Passage Two Questions 16 to 20 are based on the following passage: The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with humanlike ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as plex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (軟件 ) or by altering the architecture but that too will happen. I think it certain that in decades, not centuries, machines of silicon (硅 ) will arise first to r
