LSAT-13-1-1 【live in Mars】

pocahontas

1. It is probably within the reach of human technology to make the climate of Mars inhabitable. It might be several centuries before people could live there, even with breathing apparatuses, but some of the world’s great temples and cathedrals took centuries to build. Research efforts now are justified if there is even a chance of making another planet inhabitable. Besides, the intellectual exercise of understanding how the Martian atmosphere might be changed could help in understanding atmospheric changes inadvertently triggered by human activity on Earth.

The main point of the argument is that

(A) it is probably technologically possible for humankind to alter the climate of Mars

(B) it would take several centuries to make Mars even marginally inhabitable

(C) making Mars inhabitable is an effort comparable to building a great temple or cathedral

(D) research efforts aimed at discovering how to change the climate of Mars are justified

(E) efforts to change the climate of Mars could facilitate understanding of the Earth’s climate

the key's d.但是文中说的“Research efforts now are justified if there is even a chance of making another planet inhabitable. ”和D中的“research efforts aimed at discovering how to change the climate of Mars are justified

”不一致啊？文中好像没有提到how to change。

It is probably within the reach of human technology to make the climate of Mars inhabitable

MAIN IDEA应看文章要表达的意思，而不能局限语个别话，这是和INFER的区别

那通过这句话不是应该选a了吗？

lawyer_1

我贴那句话的意思是说原文是有提到how to change。文章的main idea还是有看全篇要表达的意思

文章的意思：作这研究技术上可行，时间也不是问题，若有机会让M适于居住，研究的努力还是值得的，研究还有附带好处。说来说去还是说研究是值得的。即D

if there is even a chance of making another planet inhabitable和if there is a chance of making another planet inhabitable在语气上是截然不同的.翻译过来,前者是"就算只有a chance ......"后者是"如果有a chance ......"

Spot the question type: Main point.

* Strategy

Always looking for the biggest concept with the most support, which is to say, you want to find out what is the point, conclusion, that author seeks to establish.

Core of the argument:

P1: Probably that our technology can make the climate of mars inhabitable

P2: it might be several centuries before people could live there, even with breathing apparatuses, but sme of the worlds' great temples and cathedrals took centuries to build.

P3: beside, the intellectual exercise of understanding how the Martian atmosphere might be changed could help in understanding atmospheric changes inadvertently triggered by human activity on Earth.

C: If there is even a chance of making another planet inhabitable, research efforts now are justified.

So, apparently, the biggest concept that the author seeks to build is - the research is justified due to " so many benefits " . Such as the benefit of living in mars by changing its weather, and understanding the climate damages caused by earth.

Let us dive into the options,.

A. It talked about a thing could be happened only if the research is justified.

B. It mentions the infos of the premises.

C. I don't think that anyone would choose this one, but if you do, you might need to enhance your reading skills.

D. Perfect answers.

E. it is true; however, it is not the main point of the argument.
