The arctic national wildlife refuge is home to caribou, moose, musk oxen, wolves, foxes, grizzlies, polar bears and migratory birds. leaders in the oil industry believe the refuge is the perfect site for the “environmentally sensitive exploration” of oil. environmentalists are wondering: what will become of the wildlife? president george w. bush, oil-industry leaders and others believe that americans will benefit from the oil that lies under the snow-filled surface of the refuge. in their opinion, the oil will reduce high fuel prices and decrease our need for oil from other countries. i believe the cost of such drilling is too high. i agree with environmentalists who fear that drilling will disturb the migration of more than 130,000 caribou. each spring, the caribou travel 400 miles to give birth on the coastal plain. in this area of the refuge, there are fewer predators. in addition, experts say that the oil in the area adds up to less than a six-month supply. is such a small amount of oil worth the risk drilling poses to these animals? americans are the largest consumers of oil. instead of drilling for oil, we should decrease our need for foreign oil simply by using less. we must all work together to cut back on the oil we use in order to preserve the wildlife of the arctic national wildlife refuge. what type of argument is used in this paragraph? i believe the cost of such drilling is too high. i agree with environmentalists who fear that drilling will disturb the migration of more than 130,000 caribou. each spring, the caribou travel 400 miles to give birth on the coastal plain. in this area of the refuge, there are fewer predators. in addition, experts say that the oil in the area adds up to less than a six-month supply. is such a small amount of oil worth the risk drilling poses to these animals? a. appeal to emotion c. appeal to logic b. bandwagon d. none of the above select the best answer from the choices provided a b c d

Industrialization in europe changed the way people lived. the urban working class came into being, and with it came the drudgery of work. which two parts of this excerpt from franz kafka's the metamorphosis most closely reflect this impact of industrialization on people's lives? "what's happened to me? " he thought. it wasn't a dream. his room, a proper human room although a little too small, lay peacefully between its four familiar walls. a collection of textile samples lay spread out on the table—samsa was a travelling salesman—and above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. it showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer. gregor then turned to look out the window at the dull weather. drops of rain could be heard hitting the pane, which made him feel quite sad. "how about if i sleep a little bit longer and forget all this nonsense," he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn't get into that position. however hard he threw himself onto his right, he always rolled back to where he was. he must have tried it a hundred times, shut his eyes so that he wouldn't have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before. "oh, no", he thought, "what a strenuous career it is that i've chosen! travelling day in and day out. doing business like this takes much more effort than doing your own business at home, and on top of that there's the curse of travelling, worries about making train connections, bad and irregular food, contact with different people all the time so that you can never get to know anyone or become friendly with them. they can all go away! " he felt a slight itch up on his belly; pushed himself slowly up on his back towards the headboard so that he could lift his head better; found where the itch was, and saw that it was covered with lots of little white spots which he didn't know what to make of; and when he tried to feel the place with one of his legs he drew it quickly back because as soon as he touched it he was overcome by a cold shudder. he slid back into his former position. "getting up early all the time", he thought, "it makes you stupid. you've got to get enough sleep. other travelling salesmen live a life of luxury. for instance, whenever i go back to the guest house during the morning to copy out the contract, these gentlemen are always still sitting there eating their breakfasts. i ought to just try that with my boss; i'd get kicked out on the spot. but who knows, maybe that would be the best thing for me. if i didn't have my parents to think about i'd have given in my notice a long time ago, i'd have gone up to the boss and told him just what i think, tell him everything i would, let him know just what i feel."
