Example Input: Article: When people get bad toothaches, they often have to eat soft, easily chewed food. When lions get bad toothaches, they eat people? That' s the conclusion of a zoologist at the Field Museum of Natural History in Chicago and a dentist who works on carnivores ., Lions don't normally prey on people. Every once in a while, however, a lion will go on a human-eating diet. The most famous such tragedy happened in 1898, when two lions killed and ate 135 railway workers in prefix = st1 /Kenya. Examining the preserved skulls of the two big cats, zoologist Bruce Patterson and dentist Ellis Neiburger found that both animals had been suffering from several dental and |aw problems. One lion had three missing teeth and a loose, unsteady lower canine that was probably useless. Canines are pointed teeth that hunting animals use for gripping and piercing prey ) .The two lions might have been so badly disabled that they couldn't bite down forcefully, say the researchers. Consequently, the lions might have abandoned their normal, more difficult prey and turned to humans. "Humans are easy preys, " said Patterson. "We're very slow, we don't hear very well, and we don* t see very well in the darkness. " The research calls their idea the Infirmity Theory. It was inspired partly by the work of Jim Corbett, a tiger hunter in Indiain the 1930s. Corbett was regularly called in to hunt tigers that had been dining on Indian villagers. Time after time, Patterson discovered that the killer tigers were suffering from some ill-healthy conditions.
Answer: reasons for some lions eating people
Example Output: The original aim of the study is to look for _ .

Example Input: Article: Five times in the earth's history, some three-quarters of all living species disappeared forever-and within a short period of time. Those species losses stand for a major change in the planet's ecology . Clues to these changes can be seen in the fossils and rock layers. Today, human activities are driving species to die out at a rate never seen before. And this loss of species really does matter, said Anita Narwani. She works at the University of Michigan in Ann Arbor. That's because the diversity of species in an ecosystem provides people with all types of services we can't do without. Trees provide oxygen for us to breathe. At the same time, they remove carbon from the air which is a cause of global warming. Plants help clean air and water. Animals move seeds from one area to another. A broad range of living resources also provides people with food, shelter and medicine. Narwani wanted to find out how important the diversity of species is for people. So she teamed up with other ecologists to review more than 1,700 studies. They found that more diverse parts of the earth tend to do well in things like removing carbon and providing us with wood and other natural resources. _ were also better at keeping fisheries large and healthy so that they could feed many people. Unfortunately, the diversity of species is in steep drop. It is too soon to say that the earth is undergoing a sixth mass extinction, Narwani said. She said a mass extinction means the loss of 75 percent of species over 2 million years or less. We haven't lost that many - at least not yet. But according to her, if species losses continue so fast, such a mass extinction could occur in just 300 years. The new findings highlight the potential for humans to use up many of the resources on which we now depend. As people learn more, however, they can take steps to lessen those risks. People should protect ecosystems so that they can continue to provide us with their services.
Answer: many people know the importance of protecting wildlife
Example Output: Narwani and her team found that _ .

Example Input: Article: Dad was lying in the hospital weakly, but his smile was as sure as ever . It was another attack of lung illness. My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from hospital and look after him. But I longed to be able to let him know that we cared about him too, even when we weren't with him. Then I remembered a family tradition when our children were small. When leaving our grandparents' home after a visit, each child would write a love note to their grandparents. We hid notes in a box, under a hairbrush or next to the phone or even in the microwave oven. For days, our grandparents would smile as they discovered these reminders of our love. So as I tidied Dad's kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, "Dad, I put the food in the fridge so it wouldn't spoil". Some expressed my love, "Dad, I hope you will sleep well in your new bed." Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, "Dad, if you have found this note, you must be feeling better. We are so glad!" Just like his medicine strengthened him physically, these "emotional vitamins" would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, "Pretty good. I just found your note under my pillow upstairs!"
Answer: had suffered from the same illness before.
