Read the following article and answer the question. Article: Dolphins call out the specific names of loved ones when they become separated, a study finds. Other than humans, they are the only animals known to do this, according to the study. The big difference with dolphins is that these communications consist of whistles , not words. Earlier research found that dolphins have a "signature whistle" that would be somewhat like human shouting, "Hey everybody! I'm an adult healthy male named George, and I mean you no harm. " The new finding is that dolphins also say the names of certain other dolphins. "Animals produced copies of the same sound when they were separated from a close partner. This supports our belief that dolphins copy another animal's signature whistle when they want to reunite with that animal," Stephanie King, who led the study, says. King and her colleagues collected acoustic data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009. The researchers also studied four adult male dolphins _ at the Seas Aquarium, also in Florida. Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins. "A dolphin uses its signature whistle to broadcast its identity and announce its presence. The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other," King explains. "Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency ." The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated. These "names" are always used in positive situations, and are only directed toward loved ones. While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system. Question: Where is the passage probably taken from? Answer:

OPTIONS:
- A magazine about scientific advances.
- A website about various animals.
- A report on animal acoustics.
- An essay about the relationship between humans and animals.

Answer: A website about various animals.

Read the following article and answer the question. Article: The light from the campfire brightened the darkness, but it could not prevent the damp cold of Dennis's Swamp creeping into their bones. It was a strange place. Martin and Tom wished that they had not accepted Jack's _ . They liked camping, but not near this swamp. "So," Martin asked as they sat watching the hot coals. "How did this place get its name?" "Are you sure you want to hear it ? It's a scary story," warned Jack. "Of course!" cried out Tom. "If there were anything to be scared of, you wouldn't have chosen this place!" "Ok, but don't say I didn't warn you," said Jack, and he began this tale. "Way back in time, a man called Dennis tried to start a farm here. He built that cottage over there to live in. In those days, the area looked quite different ---- it was covered with tall trees and the swamp was a crystal-clear river. After three hard years, Dennis had cleared several fields and planted crops. He was so proud of his success that he refused to listen to advice. "'You are clearing too much land,' warned one old man. ' The land is a living thing. It will hit back at you if you abuse it. ' "'Silly fool,' said Dennis to himself. 'If I clear more land, I can grow more crops. I'll become wealthier. He's just jealous!'" "Dennis continued to chop down trees. Small animals that relied on them for food and shelter were destroyed. He was so eager to expand his farm that he did not notice the river flowing slowly towards his door. He did not notice salt seeping to the surface of the land. He did not notice swamp plants choking all the native plants." "What happened?" Martin asked. It was growing colder. He trembled, twisting his body closer to the fire. "The land hit back ---- just as the old man warned," Jack shrugged. "Dennis disappeared. Old folks around here believe that swamp plants moved up from the river and dragged him underwater. His body was never found." "What a stupid story," laughed Tom. "Plants can't ..." Before he had finished speaking, he screamed and fainted . The other two boys jumped up... Question: What lesson can we learn from the story of Dennis? Answer:

OPTIONS:
- Grasp all, lose all
- No sweat, no sweet.
- It is no use crying over spilt milk
- He who makes no mistakes makes nothing.

Answer: Grasp all, lose all

Read the following article and answer the question. Article: Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help? Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind. Consider your emotions. You might think that emotions are the enemy of decision making, but in fact they're a part of it. Whenever you make up your mind, your brain's emotional center is active. University of Southern California scientist, Antonio Damasio, has studied people with damage to only the emotional parts of their brains, and found that they were unable to make basic choices about what to wear or eat. Damasio thinks this may be because our brains store emotional memories of past choices, which we use to help the present decision making. However, making choices under the influence of an emotion can greatly affect the result. Take anger, for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems anger can lead us to make quick decisions without much thinking. All emotions affect our thinking and motivation , so it may be best to avoid making important decisions under their influence. Yet strangely there's one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world. Question: According to the text, what may help us make better decisions? Answer:

OPTIONS:
- To think about happy times.
- To make many decisions at a time.
- To stop feeling regretful about the past.
- To learn about the process of decision-making.

Answer:
To learn about the process of decision-making.
