Plants will emit an increased amount of heat when they are______________.

B.facing an infrared scanner
C.in poor physical condition

参考答案:C
参考解析:
依据文章第二自然段第2行“an infrared scanner measured the heat emitted by crops.The data were transformed into a color-coded map showing where plants were running’evers’”,说明植物在发“高烧”,也就是说,“身体状况”不佳时才会散发热,所以选项C符合题意。
