GMAT邏輯真題題目一:Most of the world's supply of uranium currently comesfrom mines. It is possible to extracturanium from seawater, but the cost of doing so is greater than the price thaturanium fetches on the world market. Therefore, until the cost of extracting uranium from seawater cansomehow be reduced, this method of obtaining uranium is unlikely to becommercially viable.
Which of the following would it be most useful todetermine in evaluating the argument?
(A) Whether the uranium in deposits on land is rapidlybeing depleted
(B) Whether most uranium is used near where it is mined
(C) Whether there are any technological advances thatshow promise of reducing the cost of extracting uranium from seawater
(D) Whether the total amount of uranium in seawater issignificantly greater than the total amount of uranium on land
(E) Whether uranium can be extracted from freshwater at acost similar to the cost of extracting it from seawater
GMAT邏輯真題答案:
參考答案: A
思路:B:是否uranium是在near where it is mined被用的,與uranium從哪開採出來的'成本高低無關係,所以跟結論也無關係;
C:technological advances是無關詞。有這樣的技術,也不能確定這種技術會被使用,也就是說,不確定cost是否會真的會下降;有沒有這樣的技術和最終from seawater的cost降下來之間沒有“必然”聯繫。 有它可以,沒它也沒什麼!!
D:uranium的儲存量到底在seawater高還是land高,這不能決定誰的cost高低,從而也不能決定結論是否成立;
E:freshwater無關名詞。把from freshwater和from seawater比cost是沒有意義的。我們這裏需要比from seawater和from land的cost;
A:是否uranium將會很快消耗光,這就預示着是否uranium on the worldmarket的價格是否會有巨大上漲,也就是uraniumcost on the world market是否會超過from seawater的uranium, 也就決定了是否this method is commerciallyviable。這是正確答案。
GMAT邏輯真題題目二:Urban air contains more sulfur dioxide than does ruralair, and plants in cities typically grow more slowly than do plants in ruralareas. In an experiment to see how muchof the difference in growth is due to sulfur dioxide, classes in an urban and arural school grew plants in greenhouses at their schools and filtered thegreenhouse air to eliminate sulfur dioxide. Plants in the urban greenhouse grew more slowly than those in the ruralgreenhouse.
Which of the following, if true, would it be mostimportant to take into account in evaluating the result?
(A) The urban school was located in a part of the city inwhich levels of sulfur dioxide in the air were usually far lower than istypical for urban areas.
(B) At both schools, the plants in the greenhouses grewmuch more quickly than did plants planted outdoors in plots near thegreenhouses.
(C) The urban class conducting the experiment was largerthan the rural class conducting the experiment.
(D) Heavy vehicular traffic such as is found in citiesconstantly deposits grime on greenhouse windows, reducing the amount of lightthat reaches the plants inside.
(E) Because of the higher levels of sulfur dioxide in theair at the urban school, the air filters for the urban school's greenhouse werechanged more frequently than were those at the rural school.
GMAT邏輯真題答案:
參考答案: D
思路:
A. school located在哪不是新原因。
B: 有模糊詞some,然而文章結論無絕對詞,幹掉!;
C: fullerenes是如何形成的,跟檢測the state of earth’s crust無關;
A: 是迷惑的選項。confirming礦石含有fullerenes 需要仔細實驗,說明要在礦石中發現fullerenes挺麻煩,但是並不能說明發現fullerenes會對檢測fullerenes產生影響;
D: fullerenes晶體結構我們不知道,無法從它來了解the state of earth’s crust. 正確答案!
