A mysterious "black cloud" approaches the earth -- our planet’ s weather is severely affected.
Throughout the rest of June and July temperatures rose steadily all over the Earth. In the British Isles the temperature climbed through the eighties, into the nineties, and moved towards the hundred mark. People complained, but there was no serious disaster.
The death number in the U. S. remained quite small, thanks largely to the air - conditioning units that had been fitted during previous years and months. Temperatures rose to the limit of human endurance throughout the whole country and people were obliged to remain indoors for weeks on end. Occasionally air - conditioning units failed and it was then that fatalities occurred. Conditions were utterly desperate throughout the tropics as may be judged from the fact that 7943 species of plants and animals became totally extinct. The survival of man himself was only possible because
A. stayed at eighty
B. ranged from eighty to ninety
C. approached one hundred
D. exceeded the hundred mark
