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

"Worse than useless," fumed Darrell Issa, a Republican congressman from California, on March 19th, when the House Judiciary Committee held a hearing on the Immigration and Naturalization Service. "Terrible, and getting worse," added Zoe Lofgren, a Democratic colleague who has kept a watchful eye on the INS for ten years.
Committee members lined up to take swings at James Ziglar, the head of the INS. He explained, somewhat pathetically, that "outdated procedures" had kept the visa-processing wheels grinding slowly through a backlog of applications. He also had some new rules in mind to tighten up visas. Speeding up the paperwork -- and getting more of it on to computers -- is vital, but the September attacks have exposed the tension between the agency’s two jobs: on the one hand enforcing the security of America’s borders, and on the other granting privileges such as work permits to foreigners.

B. its merging with the Customs Service.
C. other security recommendations.
D. its separation into two bodies.
