Questiоns 31-43. Reаd the fоllоwing pаssаge carefully before you choose your answers.(The following passage is excerpted from a nonfiction book published in the late twentieth century.) Climatologists speak of thunderstorms pregnantwith tornadoes, storm-breeding clouds more than twicethe height of Mount Everest; they speak of funicularenvelopes and anvil clouds with pendant mammati andof thermal instability of winds in cyclonic vorticity, 5of rotatory columns of air torquing at velocities up tothree hundred miles an hour (although no anemometerin the direct path of a storm has survived), funnels thatcan move over the ground at the speed of a strollingman or at the rate of a barrel-assing semi on the turnpike; 10they say the width of the destruction can be thedistance between home plate and deep center field andits length the hundred miles between New York Cityand Philadelphia. A tornado, although more violentthan a much longer lasting hurricane, has a life 15measured in minutes, and weathercasters watch itsnuff out as it was born: unnamed. I know here a grandfather, a man as bald as if acyclonic wind had taken his scalp—something wit-nesses claim has happened elsewhere—who calls 20twisters Old Nell, and he threatens to set cryingchildren outside the back door for her to carry off.People who have seen Old Nell close, up under herskirt, talk about her colors: pastel-pink, black, blue,gray, and a survivor said this: All at once a big hole 25opened in the sky with a mass of cherry-red, a yellowtinge in the center, and another said: a funnel withbeautiful electric-blue light, and a third person: It wasglowing like it was illuminated from the inside. Thewitnesses speak of shapes: a formless black mass, a 30cone, cylinder, tube, ribbon, pendant, thrashing hose,dangling lariat, writhing snake, elephant trunk. Theytell of ponds being vacuumed dry, . . . chickens cleanpluckedfrom beak to bum, water pulled straight upout of toilet bowls, . . . a wife killed after being jerked 35through a car window, a child carried two miles and setdown with only scratches, a Cottonwood Falls mother(fearful of wind) cured of chronic headaches when atwister passed harmlessly within a few feet of herhouse, and, just south of Chase, a woman blown out of 40her living room window and dropped unhurt sixty feetaway and falling unbroken beside her a phonographrecord of “Stormy Weather.”
