Choose the letter A, B, C or D to answer these following questions

A new study published in the journal Science shows definitive evidence of organic matter on the surface of Mars. The data was collected by NASA's nuclear-powered rover Curiosity. It confirms earlier findings that Mars, the Red Planet once contained carbon-based compounds. These compounds – also called organic molecules – are essential ingredients for life as scientists understand it.

The organic molecules were found in Mars's Gale Crater, a large area that may have been a watery lake over three billion years ago. The rover encountered traces of the molecule in rocks extracted from the area. The rocks also contain sulfur, which scientists speculate helped preserve the organics even when the rocks were exposed to the harsh radiation on the surface of the planet.

Scientists are quick to state that the presence of these organic molecules is not sufficient evidence for ancient life on Mars, as the molecules could have been formed by non-living processes. But it's still one of the most astonishing discoveries, which could lead to future revelations. Especially when one considers the other startling find that Curiosity uncovered around five years ago.

Question: Why are the evidences in sufficient to claim life on Mars?

A. The molecules could have been formed by non-living processes.

B. The molecules exist everywhere on the planet.

C. All planets have these molecules.

D. The existence of these molecules is not strong enough.

VI. Choose the best answers.

Rainforests circle the globe for twenty degrees of latitude on both sides the equator. In that relatively narrow band of the planet, more than half of all the species of plants and animals in the world make their home.  Sever hundred different varieties of trees may grow in a single acre, and just one of those trees may be the habitat for more than ten thousands kinds of spiders ants, and other insects. More species of amphibians, birds, insects, mammals and reptiles live in rainforests than anywhere else on earth.

Unfortunately, half of the world's rainforests have already been destroyed and at the current rate, another 25 percent will be lost by the year 200. Scientists estimate that as many as fifty million acres are destroyed annually. In other words, every sixty seconds, one hundred acres of rainforest is cleared. When this happens, constant rains- erode the former forest floor,  thin layer of soil no longer supports plant life, and the ecology of the region is altered forever. Thousands of species of plants and animals are condemned to  extinction and since we aren't able to predict the ramifications of this loss o a  delicate global ecology, we don't know what we may be doing to the future the human species as well.

46. 'What is the point of view that the author expresses in this passage?

a.     The author believes that the rainforest will survive.

b.     The author believes that preserving the rainforest is important to global ecology.

c.     The author believes that he can predict the future of global ecology.

d.     The author believes that the extinction of species is a natural process.

47. According to the passage, more than half of all the species of plants and animals        

a.   live in twenty rainforests.

b.  live in several hundred different varieties of trees.

c.   live in a forty-degree band of latitude.

d.  live in areas where the rainforest has been cleared.

48.    How many of the worlds rainforests are projected to be destroyed by the year 2000 if the current rate continues?

            a. All of them will be gone.                        b. Three-quarters of them will be gone.

            c. Half of them will be gone.                      d. One-quarter of them will be gone.

49. The word 'this.' in line 12 refers to …………….

            a. the destruction of the acres.                     b. the reading of the passage.

            c. the erosion of the forest floor.                 d. the constant rains.

50. What will not happen if the rainforest continues to be cleared?

a.     The land will be eroded by the rains.

b.     Many species of plants and animals that depend on the rainforest will become extinct.
