Article: Human beings are the most intelligent of all animals because we are gifted with the ability to think and reason logically. Scientists and even common people with special intelligence have made a lot of inventions and contributions to modern lifestyle in the past. "Houses" have been the most popular area for discoveries and inventions in the past and even now. Many household items have been the result of inventions of people who desired better functioning of the existent products. Every individual has intelligence and if it is used properly for the right purpose it leads to invention of a new tool or device. Many new household inventions are made almost every day and there are specific companies, which particularly keep a record of all these inventions. A lot of inventions have been made recently in the household field. These products are patented and have trade mark licenses . The patented sliding cinch is a very simple but effective method to prevent shoulder stress and injury for those who work before computers all day long. Vanity PC is a type of computer furniture that specifically hides all the computer wires and keeps a clean and good look. All the outdoor dust, mud and snow can be kept out of the house by installing the dirt drain at the entrance of the door. Another important invention is the automatic toilet night-light, in which a small light starts when the lid of the toilet seat is opened and closes as soon as the lid is closed. These are some of the new household inventions invented mostly by common people. Thus, a variety of new household items are invented every day, which helps in a better functioning of household chores and in a more useful manner. Question: Common people can also make good inventions because _ . Yes or no, is the answer "wisdom and inspiration sometimes come from everyday life"?
No

Article: Now let's look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way. In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species. For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled. Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities. Question: From the passage we can infer that in the course of evolution _ . Yes or no, is the answer "humankind has experienced a generalization rather than specialization in ability"?
Yes

Article: Commander was my parents' cat but I knew him first. In fact, Commander was my college roommate's cat. My roommate wanted to sell Commander, but no one would buy him. I called my parents to see if they would like to adopt him. My mom had always loved cats but my dad disliked cats very much. As predicted my dad said, "No way. No cats" Fortunately for me, my dad was out of town at a math conference. So I brought Commander home. By the time he returned, both my mom and Commander had decided that Commander was going to stay. My mom said that Commander was going to live at our house for a "trial period" while we looked for a buyer. As the months went by there was absolutely no effort to sell Commander and it became clear to my dad that Commander was there to stay. Commander started sitting by my dad as he read the newspaper and slowly my dad began to like Commander---just a little bit. By the time I came home that summer, I was surprised to see my dad carrying Commander around the house. Over the years, my parents' love for Commander grew to the point where they could not imagine life without him. Once I finished college, my parents built their dream house and they named the floor plan The Commander! They worked with the architect to design the house so that it was perfectly suited both for them and for Commander. Commander died at the age of eighteen. My mom still talks about him often and misses him, and so does my dad, which proves that not even the most determined cat-hating human being in the world can resist the charms of a cat once the cat decides he is moving in to your heart. Question: When the author's dad returned from the conference, _ . Yes or no, is the answer "the author's mother decided to keep Commander"?
No

Article: Directions : Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B, C and D. Choose the one that fits best according to the information given in the passage When top engineers in Germany wanted to build a more energy-efficient car, they headed to the natural history museum to study dolphins and sharks. But it was the boxfish that interested them. "We were surprised when this clumsy-looking fish became our model for designing an aerodynamic car",says Thomas Weber. He is the research and development chief for the car company Daimler. An aerodynamic design reduces wind drag and increases fuel efficiency. The boxfish may look clumsy, but it can start, stop ,back up and zigzag through the water with ease. And it does all this using surprisingly little energy. Daimler's bionic car is modeled on the fish's boxy skeletal system. Like the fish, the car is fast and drives easily. It's efficient too. The science behind nature-inspired inventions is called biomimicry . Biologist Janine Benyus came up with the term. As co-founder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature's best ideas. This month ,the Nature's 100 Best List will be revealed at the World Conservation Congress in Barcelona ,Spain. Benyus co-authored the list of nature inspired designs with economist Gunter Pauli. In Zimbabwe ,a country in southern Africa ,engineers designed energy-efficient buildings modeled on termite mounds . The buildings use vents to keep the air flowing and the temperature cool. A company in Atlanta ,US ,developed a self-cleaning paint modeled on the lotus leaf. When the paint dries ,it becomes bumpy ,just like the lotus leaf. Rain drops form on the bumps and roll off ,carrying dirt along with them. Nature has done billions of years of research. Only the best-designed products have survived. Companies owe Mother Nature a debt for all that... Question: What's the main idea of the passage? Yes or no, is the answer "Nature has inspired a lot of inventions and will continue to."?
No
