Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

[EX Q]: Article: Testing new drugs for safety and effectiveness is a costly process in the United States. It also can take:lot of time. Some scientists are now designing silicon computer chips that act like human organs. The scientists think they have found a way to make the process faster and more economical. The silicon computer chips are smaller than a child's hand. Each one has living cells that act and react like a human organ. The chips are being created as part of a program to test the safety of drug compounds. It is called the Tissue Chip for Drug Screening Program. It is a project of the US National Center for Advancing Tmnslational Sciences, or NCATS. Danilo Tagle is the center's Associate Director. He says a three-dimensional computer chip can be designed to act like a human lung. Some computer chips contain very small models of the human digestive system. They copy the real function or duties of the human stomach and intestine , moving when breaking down food. Drugs are added to the tiny organs for testing through instruments known as micro-tubes. Experiments with the tissue chips have produced more detailed information than tests using animal or cell models. NCATS just announced$17 million in grants to develop an entire human organ system over the next three years.
Question: Why are scientists designing silicon computer chips acting like human organs?
Options: (A) To treat the patients whose body organs don't work well. (B) To examine the health condition of human organs. (C) To make testing new drugs faster and cheaper. (D) .To further study the function of human organs.
[EX A]: C

[EX Q]: Article: Every child has written their names on the beach at some point. But whereas most people's "handwriting" is washed away, one super-rich Arab sheikh has ensure that his graffiti will last a little longer. Hamad Bin Hamdan Al Nahyan, 63, has scrawled his name in sand on an island he owns with letters so big that they be seen from space. The word "HAMAD" measures 1,000 meters high and is a staggering two miles long from the "H" to the "D" on the Al Futaisi Island. And rather than allow the writing to be washed away by the ocean, the letters actually form waterways that absorb the encroaching tide. The ruler's name is even visible on Google's map service. Hamad dreamed up the idea and had his workmen work hard for weeks to craft the enormous piece of sand graffiti. It is not known how much it cost to make. However, the sheikh boasts a personal fortune second to the Saudi king's. Hamad, also known as the "Rainbow Sheikh", is a member of the Abu Dhabi Ruling Family. He is understood to have some 200 cars including seven Mercedes 500 SELs painted in different colors of the rainbow which he stores in a giant pyramid. The Arab sheikh had a taste for doing things on a large scale. He built the world's largest truck--eight times the size of the Dodge Power Wagon, with four bedrooms inside the cabin. Hamad constructed a motor home in the shape of a giant globe which is exactly 1 millionth the size of the actual earth. Alongside his displays of wealth he has become a well-known philanthropist in medicine and supplied a complete Kinney stone operating theatre to a public hospital in Morocco where he continues to fund its stuff.
Question: Which of the following in NOT true according to the passage?
Options: (A) Hamad is a man who wants himself to be well-known from apace. (B) Hamad is a super-rich person who always does something unusual. (C) Hamad is a man who is always so mean in his family (D) Hamad is a man who boasts his fortune is second to the Saudi king's

[EX Q]: Article: Maybe you don't know the fact that the green forests we see from an airplane or from the highway can be false. Because centuries ago forests were twice as many as what they are today. A hike into many of those woods will tell different stories, too--of diseases and insects that are slowly killing trees, of some forests that are burned by fire, of logging that local people do more often. Deforestation and degradation of the world's forests mainly harm the basic ability of those ecosystems to function or provide services, such as fresh water, air, plants and animals, which benefit people everywhere and keep the balance of nature. Deforestation Forests today are a small part of what they once were. Nearly half of the world's forest cover is gone, and each year 40 million acres more are cut and replaced by agriculture and development. Over the next 45 years, wood use in the world is guessed to increase by 50 per cent over its present rate. Many of the forests that remain are severely destroyed, which harms the ability to protect birds or wild animals, and to supply natural resources to people. Deforestation also brings about between 20 per cent and 25 per cent of all air pollution causing global climate change. Degradation Forests continue to be degraded by some uses such as the gathering of wood for fuel, the arrival of pests and diseases that kill trees, the effects of climate change and poor management such as the fire, flood and so on.
Question: What do deforestation and degradation of the forests mainly harm?
Options: (A) Fresh water, air, plants, animals and people. (B) The ability of the ecosystems to function. (C) The local people's life and their health. (D) The scenery which benefits tourism.
