2月GMAT邏輯機經(jīng)：coal mining.

　　GMAT機經(jīng)每月都會有所更新，這不初冬的寒流刮來了GMAT邏輯機經(jīng)，澳際小編就在這寒冬中為大家吹來一股GMAT機經(jīng)的暖風(fēng)，為大家分享關(guān)于coal mining的機經(jīng)，希望大家能感受到這股暖意，并把它化為能量，在GMAT考試的道路上勇往直前。

　　【原始】

　　政府財政支持coal mining，所以coal mining得到很大發(fā)展，產(chǎn)量變多，民眾付的價格變低。但是考慮到環(huán)境問題，政府打算從coal mining轉(zhuǎn)化到污染更少的fuel，為了達到這個目標(biāo)，政府打算削減coal mining的財政補助，問削弱。 選項不好意思我忘了，有從價格角度來說的，還有從削減財政補助會造成什么后果的角度，好像還有一個是說其實fuel污染更大。

　　【考古】

　　Twenty years ago, Balzania put in place regulations requiring operators of surface mines to pay for the reclamation of mined-out land. Since then, reclamation technology has not improved. Yet, the average reclamation cost for a surface coal mine being reclaimed today is only four dollars per ton of coal that the mine produced, less than half what it cost to reclaim surface mines in the years immediately after the regulations took fect.

　　Which of the following, if true, most helps to account for the drop in reclamation costs described?

　　A. Even after Balzania began requiring surface mine operators to pay reclamation costs, coal mines in Balzania continued to be less expensive to operate than coal mines in almost any other country.?

　　B. In the twenty years since the regulations took fect, the use of coal as a fuel has declined from the level it was at in the previous twenty years.

　　C. Mine operators have generally ceased surface mining in the mountainous areas of Balzania because reclamation costs per ton of coal produced are particularly high for mines in such areas.

　　D. Even after Balzania began requiring surface mine operators to pay reclamation costs, surface mines continued to produce coal at a lower total cost than underground mines.?

　　E. As compared to twenty years ago, a greater percentage of the coal mined in Balzania today comes from surface mines.

　　以上就是關(guān)于GMAT機經(jīng)的全部內(nèi)容，考生朋友可以有選擇的看看，最后需要提醒各位的是，GMAT機經(jīng)雖然會對我們解題有所幫助，但是在考場中即使題目很像也要避免秒選，最后祝大家都能考出好成績。
