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

Article: This will make you think twice about dismissing the physical abilities of women. Serena Williams If know Serena Williams, then you know better than to harbor any illusions that you can take on the top female tennis player even on your best day. Nicknamed by the media as the Queen of the Court, she has won 19 Grand Slam singles titles and 13 Grand Slam doubles titles as of May 2015. By the way, she can send the ball hurtling towards your face on the excess of 120 miles per hour on her serve. Ronda "Rowdy" Rousey Former Olympic judo gold medalist Ronda 'Rowdy' Rousey has been dominating women's MMA for the past several years. She earned the nickname "The Arm Collector" for winning the majority of her fights via armbars. As of May 2015, no other female MMA has put up much of a challenge against Rousey, but some think that the next entry on this list just might give her trouble. Cristiane 'Cyborg' Justmo Many believe that Cris Cyborg will give Rousey trouble and may even have an outside chance of beating her. While Rousey is an excellent grappler owing to her judo background, Cyborg is a more well-rounded fighter with excellent standup and groundwork skills. This means that just like Rousey, Cyborg can lay some serious beatdown on you. Missy Franklin So you think you are a good swimmer. Well, no matter how good you think you are, you'll very likely still be eating Missy Franklin's pool dust. Missy is a four-time Olympic gold medalist and has also won a bunch of gold medals in the World Championships. Mirinda Carfae Do you think you can swim 2.4 miles, ride a bike for 115 miles, and still have enough gas to run for 26 miles? Mirinda Carfae certainly can and she proved that she can do it faster than any woman winning the Ironman World Championships women's division in 2010, 2013, an 2014. Question: As of May 2015, _ Yes or no, is the answer "Serena Williams has won 19 Grand Slam singles titles"?
Yes

Article: The professor stood before his class of 30 senior biology students, about to pass out the final exam. "I have been honored to be your teacher this term, and I know how hard you have all worked to prepare for this test. I also know most of you are off to medical school or graduate school next fall," he said to them. "I can well understand how much pressure you are under to keep your grades up, and because I know you are able to understand this material, I am prepared to offer an automatic "B" to anyone who would prefer not to take the final." In relief a number of students jumped up to thank the professor and left the class. The professor looked at the students who remained, and offered again, "Any other takers? This is your last chance." One more student decided to go. There were seven students left. The professor closed the door. Then he handed out the final exam. There were only two sentences typed on the paper: "Congratulations, you have just received an "A" in this class. Keep believing in yourself." I never had a professor who gave a test like that. It may seem like the easy way out of grading a lot of exams, but it's a test that any teacher in any subject could and should give. Students who don't have confidence in what they've learned are "B" students at best. The same is true for students of real life. The "A" students are those who believe in what they're doing because they've learned from both successes and failures. They have learned life's lessons, whether from formal education or the school of hard knocks, and become better people. Take your cue from Sir Edmund Hillary, the first person to reach the top of Mount Qomolangma: "It's not the mountain we conquer , but ourselves." Don't let the biggest limit be yourself. Question: The point of the story is to advise readers _ . Yes or no, is the answer "not to let themselves limit their growth"?
No
