Use the space to objectively summarize the central idea of a section of the hot zone by richard preston.

1) earth's crust is made up of relatively rigid plates that ride atop earth's hot, semiliquid mantle. (2) the plates are called tectonic because they're in constant motion. (3) they can move because earth's mantle is a very hot and semiliquid fluid called magma. (4) volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) therefore, we often find volcanoes and earthquakes along plate boundaries. (7) plates may also collide. (8) when that happens, mountain ranges are formed. (9) for example, the collision of the plate carrying the indian subcontinent created the himalayan mountains when it collided with the asian plate. which statement about this paragraph is accurate?

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
