Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life. The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado. "This is the first clear evidence of shorelines on the surface of Mars," said Boulder's research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters. "The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago."[:] Analysis of the images has shown the water carved out the canyon in which it was found, which then opened out into a valley depositing sediment which formed a delta . "Finding shorelines is a great discovery to us," said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry. Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago. The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study. Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life. Question: Which of the following statements is Not true according to the passage? Options: A: The Noachan epoch was a wet and warm era. B: The lake might have existed 3.4 billion years. C: The discovery can't fully prove that the Mars once hosted life. D: The lake traces prove that there exists life on Mars now.
Ans: D

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined to the aged.

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: A mouse looked through a crack in the wall to see the farmer and his wife opening a package; what food might it contain? He was astonished to discover that it was a mouse trap!

The chicken, with her head high, glared at the mouse and said, "Shut up. Little Ugly. This is a great concern to you, but it has nothing to do with me; I can't be troubled by it. The mouse turned to the pig and told him, "There is a mouse trap in the house." "I am so sorry, Mr. Mouse," said the pig sympathetically, "but there is nothing I can do about it but pray; you are always in my prayers." The mouse turned to the cow, who relied, " A mouse trap, am I in great danger, huh?" Now the mouse had to face the farmer's mouse trap alone. The very night a sound was heard through the house, like that of a mouse trap catching its . The farmer's wife rushed to see what was caught. In the darkness, she did not see it was a big poisonous snake whose tail the trap had caught. The snake bit the farmer's wife. The farmer rushed her to the hospital. She returned home with a fever. It is said that drinking fresh chicken soup will help treat fever, so the farmer took his sharp knife to the farmyard for the soup's main ingredient. His wife's sickness continued, so friends and neighbors came to sit with her around the clock. To feed them, the farmer killed the pig. The farmer's wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow killed to provide for all of them to eat.
