None Q. 4 A pregnant wild elephant in Kerala’s Silent Valley Forest fell in victim to an act of human cruelty after a pineapple filled with powerful crackers offered by a man exploded in her mouth when she chomped on it. Her jaw was broken, and she was unable to eat after she chewed the pineapple, and it exploded in her mouth. The incident took place in the fringe areas of the Silent Valley in Attappadi, Kerala. The post-mortem revealed that the pachyderm was pregnant. The issue of the pachyderm’s tragic death came to light after Mohan Krishnan, a forest officer, posted an emotional note on his Facebook page, narrating the death of the elephant in the waters of the Velliyar River. In which of the following cases the reason is same as in case of the killing of the elephant mentioned in the paragraph?Deselect Answer Tens of thousands of pangolins are poached every year, killed for their scales for use in traditional Chinese medicine and for their meat, a delicacy among some ultra-wealthy in China and Vietnam. In 2010, a study led by the World-Wide Fund for Nature projected that a sea level rise of 11 inches could reduce the number of tigers in the Sundarbans, by 96 per cent within a few decades. While the government did not provide any numbers for deaths caused by other big cats, conflicts with leopards have become so common that villagers regularly mount hunting parties when one ventures near their homes, threatening children and livestock. As the human population in China continues to grow, pandas' habitat gets taken over by development, pushing them into smaller and less livable areas which lead to food shortages and it’s the main reason that panda populations have declined If such an increase continues in deforestation, all animals will suffer None Q. 5 The best way to create a successful party is to visualize the guests discussing it with friends the next day.

Which one of the following illustrates a principle most similar to that illustrated by the passage?Deselect Answer When planning a vacation, some travelers decide first where they want to go, and then plan their route. But, for most people, financial issues must also be taken into account. When landscaping the grounds of a new home, you should start with the topsoil and then choose your shrubbery and other foliage. Good moviemakers do not extemporaneously film their movies in one or two days with no script; a movie cannot be separated from the story upon which it is based. In negotiating an employment contract, the best method is to make as many outlandish demands as possible and then agree to forgo the most outrageous of them. To make a great golf shot, you should picture the ball landing where you want it to land, and then you will be able to line up your body and your club accordingly. None Q. 6 Gustav Klimt lived and worked in the same City as:Deselect Answer Thomas Mann Johann Wolfgang von Goethe Albrecht Dürer Hieronymous Bosch Sigmund Freud None Q. 7 Directions: Read the following passage and answer next 3 questions that follow. Refer to the textto check your answers when appropriate."Click!" That's the sound of safety. That's the sound of survival. That's the sound of a seat belt locking in place. Seat belts save lives and that's a fact. That's why I don't drive anywhere until mine is on tight. Choosing to wear your seat belt is a simple as choosing between ife and death. Which one do you choose?Think about it. When you're driving in a car, you may be going 60 MPH or faster. That car is zipping down the road. Then somebody ahead of you locks up his or her brakes. Your driver doesn't have time to stop. The car that you are in crashes. Your car was going 60 miles per hour. Now it has suddenly stopped. Your body, however, is still going 60 MPH. What's going to stop your body? Will it be the windshield or your seat belt? Every time that you get into a car you make that choice. I choose the seat belt.Some people think that seat belts are uncool. They think that seat belts cramp their style, or that seat belts are uncomfortable. To them I say, what's more uncomfortable? Wearing a seat belt or flying through a car windshield? What's more uncool? Being safely anchored to a car, or skidding across the road in your jean shorts? Wearing a seat belt is both cooler and more comfortable than the alternatives.Let's just take a closer look at your choices. If you are not wearing your seat belt, you can hop around the car and slide in and out of your seat easily. That sounds like a lot of fun. But, you are also more likely to die or suffer serious injuries. If you are wearing a seat belt, you have to stay in your seat. That's no fun. But, you are much more likely to walk away unharmed from a car accident. Hmmm... A small pleasure for a serious pain. That's a tough choice. I think that I'll avoid the serious pain.How about giving money away? Do you like to give your money away? Probably not. And when you don't wear your seat belt, you are begging to give your money away. That's because kids are required to wear seat belts in every state in America. If you're riding in a car, and you don't have a seat belt on, the police can give you or your driver a ticket. Then you will have to give money to the city. I'd rather keep my money, but you can spend yours how you want.Wearing a seat belt does not make you invincible. You can still get hurt or killed while wearing your seat belt. But wearing them has proven to be safer than driving without them. You are much less likely to be killed in a car wreck if you are wearing a seat belt. You are much less likely to get seriously injured if you are wearing one. So why not take the safer way? Why not go the way that has been proven to result in fewer deaths? You do want to live, don't you?Which best expresses the author's main purpose in writing this text?Deselect Answer To inform readers about seat belt laws To persuade readers to wear seat belts To entertain readers with stories and jokes about seat belts To describe what car accidents are like without seat belts To explain readers how to wear a seatbelt None Q. 8 Which best describes the text structure in the fourth paragraph?Deselect Answer Compare and contrast Chronological order Sequential order Problem and solution Matching Information None Q. 9 Which best defines the word alternatives as it is used in the third paragraph?Deselect Answer Being safe Being unsafe Other choices Driving fast Other seatbelts None Q. 10 People with an A-positive blood type may safely donate blood to those with which blood type?Deselect Answer A negative B positive O negative AB positive AB negative None Q. 11 An allele that codes for all actin molecules to be synthesized in linear chains would result inDeselect Answer immovable muscles smooth muscle tissue normal sarcomere structure degeneration of muscle tissue muscle tendons that cannot attach None Q. 12 A genetic mutation that adds a nucleotide to a protein-coding sequence of DNA creates an early stop codon.
