Scientists claim that air pollution causes a decline in the world's average air temperature, In order to prove that theory, ecologists have turned to historical data in relation to especially huge volcanic eruptions. They suspect that volcanoes effect weather changes that are similar to air pollution.
One source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indies (the former name of the Republic of Indonesia), in April 1815. The largest recorded volcanic eruption of Tambora threw 150 million tons of fine ash into the stratosphere. The ash from the volcano spreads worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation into space and thus cool the earth. For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5°F. During the next twenty-four months, England suffered one of the coldest periods of its history. Farmers' records from April 1815 to December 1818 indicate frost throughout the spring and summer and sharp decreases in crop and livestock markets. Since there was a time lag of, several years between cause and effect, by the time the world agricultural commodity community had deteriorated, no one realized the cause.
Ecologists today warn that we face a twofold menace. The ever-present possibility of volcanic eruptions, such as that of Mt. St. Helens in Washington, added to man's pollution of the atmosphere with oil, gas, coal, and other polluting substances, may bring us increasingly colder weather.
According to the passage, the effects of Tambora's eruption were______
No one realized the cause of the deterioration of the world agricultural commodity market
A legislative body has the power not only to pass new laws, _______ repeal laws that have
Chris Baildon, tall and lean, was in his early thirties, and the end-product of an old decayed island family.
Chris shared the too large house with his father, an arthritic and difficult man, anda wasp-tongued aunt, whose complaints ended only when she slept.
The father and his sister, Chris's Aunt Agatha, engaged in shrill-voiced arguments over nothing. The continuous exchanges further confused their foolish wits, and yet held off an unendurable loneliness. They held a common grievance against Chris, openly holding him to blame for their miserable existence. He should long ago have lifted them from poverty, for had they not sacrificed everything to send him to England and Oxford University？
Driven by creditors or pressing desires, earlier Baildons had long ago cheaply disposed of valuable properties. Brother and sister never ceased to remind each other of the depressing fact that their ancestors had wasted their inheritance. This, in fact, was their only other point of agreement.
A few years earlier Agatha had announced that she intended doing something about repairing the family fortunes. The many empty rooms could be rented to selected guests. She would establish, not a boarding-house, but a home for ladies and gentlemen, and make a tidy profit. She threw herself into the venture with a noisy fury. Old furniture was polished; rugs and carpets were beaten, floors painted, long-stored mattresses, pillows and bed-linen aired and sweetened in the sun.
Agatha, with a fine air of defiance, took the copy for a modest advertisement to the press. Two guests were lured by the promise of beautiful gourmet meals, a home atmosphere in an historic mansion, the company of well-brought-up ladies and gentlemen. The two, one a bank clerk and the other a maiden lady employed in a bookshop, arrived simultaneously, whereupon Agatha condescended to show them to their rooms, and promptly forgot about them. There was no hot water. Dinner time found Baildon and Agatha sharing half a cold chicken and a few boiled potatoes in the dining room's gloomy vastness.
When the guests came timidly to inquire about the dining-hours, and to point out that there were no sheets on the beds, no water in the pitchers, no towels on their racks, Agatha reminded them that the Baildons were not inn-keepers, and then treated them to an account of the family's past glories.
His father and aunt blamed Chris for______
