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: What was the role of sulfur in the rocks?

A. It helped preserve the organics

B. It formed the rocks

Read the passage below and decide whether the statements are TRUE or FALSE?

Long ago, people thought the Moon was a god and we would never be able to reach it. However, the invention of telescopes in 1608 enabled people to learn that the Moon is just another planetary body. And mankind’s dream of walking on the Moon suddenly seemed possible.

The dream came true on July 20th, 1969 when Neil Armstrong, Buzz Aldrin, and Michael Collins flew to the Moon as part of the Apollo 11 lunar mission. Neil Armstrong was the first to step onto the Moon. After admiring the tranquil, desolate beauty of the Moon’s surface, Neil Armstrong and Buzz Aldrin completed their mission, while Collins stayed in orbit to maintain the systems on board the spacecraft.

During the stay of more than twenty-one hours on the Moon’s surface, the astronauts found no rain or wind at all. The Moon was like a desert with plains, mountains, and valleys. The surface was covered with dust, which was so thick that they left footprints where they had walked. They left a United States of America flag there and return to Earth with forty-six pounds of moon rock for scientific study.

Question: The climate on the Moon was unfriendly, with a lot of rain and wind

A. True

B. False
