Halo kawan kawan,

Mari kita bahas soal berikut ini

 

Soal:

Right now, the amount of carbon dioxide in our environment is hovering at 400 parts per million a number that is already large enough to start affecting our environment.Carbon dioxide is greenhouse gas, meaning that it traps heat within the Earth’s atmosphere. That is why governments around the world are trying to reduce the amount of carbon dioxide put into the atmosphere annually, in the hopes that the planet will not get so warm that parts of the planet become uninhabitable. But what if those reductions do not happen, and instead, everything goes horribly wrong?

Looking at a computer model of a world completely covered in water (a simple analog of the Earth, which is 71 percent covered by water) Popp and colleagues looked at what would happen if the carbon dioxide levels rose to staggering levels. They found that when the level of carbon dioxide in the atmosphere reached 1 .520 parts per million, temperatures at the surface of the world would reach nearly 135 degrees fahrenheit, evaporating vast amounts of water into the atmosphere, and sending them high up into the atmosphere near space. In this scenario, called the “moist greenhouse” in the paper, Popp estimates that water could easily escape from the water world’s atmosphere into space. Worse, they found . that once moist greenhouse conditions were reached, they could not be reversed, even by removing the excess carbon dioxide.

A similar situation could happen in a few bil lion years as the sun brightens in the natural course of its evolution, sending out so much more heat and light that the temperature of the Earth’s surface rises, creating a similar moist greenhouse effect.

But there is no need to worry right now about whether the world wi ll end in fire or gas. Given the lengthy time scale to reach either situation (millions if not billions of years) , these are more geological doomsday scenarios than human ones. Is not that comforting?

Which of the following is the restatement of the sentence . . . ‘the planet will not get so warm that parts of the planet become uninhabitable’ in paragraph 1?
(A) People cannot live in parts of the planet if it is too warm.
(B) People can live in parts of the planet if it is too warm.
(C) People cannot live in parts of the planet if it is not warm.
(D) The planet is too warm to live in.
(E) The planet is warm enough to live in.

Jawaban:

Jawabannya adalah “(A) People cannot live in parts of the planet if it is too warm”.

Soal menanyakan paraphrase dari kalimat di atas.

Kalimatnya adalah “the planet will not get so warm that parts of the planet become uninhabitable” (planet ini tidak akan menjadi begitu hangat sehingga bagian-bagian dari planet ini menjadi tidak dapat dihuni).

Maksud dari kalimat di atas adalah, jika beberapa bagian di bumi menjadi terlalu hangat, manusia tidak bisa tinggal di daerah tersebut.

Penjelasan:

Jadi, jawaban yang benar adalah A.

 

Semoga jawaban dan penjelasan diatas dapat membantu kawan belajar ya. apabila ada pertanyaan silakan berkomentar dibawah ini.

 

Salam sukses selalu
