Read the following article and select the best answer. Article: I was born in Minneapolis. The city is in my blood. But I live in the country, and have been forced to deal with things that are difficult. One thing I've always had trouble with is birds. How could anyone enjoy staring out of the window for hours at these creatures? My mother had always been one of those ridiculous birdwatcher types. She tried to raise her children to have respect for wildlife, but with little effect on me. One evening, a bird had been sitting on the same perch , as if frozen, for ten minutes. My mother got a ladder and took the bird from his perch. She inspected him. It seemed that his tongue was hurt, and that he was unable to drink from the feeder. My mother handed him to me while she went inside for an eyedropper . Never in my life had I felt as frightened as when I was holding that tiny life in my hands. I placed the eyedropper inside the long beak. At first, the bird only trembled, but finally he managed to swallow. After a few minutes, he glided to a tree nearby and returned again. He flew to the tree and then back to me again and again. It didn't take me long to realize that he was sending me a message, a sort of "SOS". I walked toward the tree, where I found the tiny creature trembling in the evening air. I slowly reached into the grass to pick up the bird. "Please, be okay." He had asked me for help. Now he owed me a favor in return and I was asking him to stay alive. However, what I saw was another dead bird lying besides the bird. It must have been a very sad picture: a child wiping her face with her one free hand, while the other palm was cupped around a tiny, dying creature. Fate was taking its own course. Its pulse was hardly noticeable, and the body was growing colder. I realized there were some things I could change and some I must simply accept. In either way, the two worlds sometimes collide and strangers must ask for, and be willing to receive, help from others. Without this, survival is not only impossible, but meaningless. Question: Why did the bird fly to the author again and again? - To thank her for saving him. - To look for food to feed the dying bird. - To warn her of danger. - To ask for help for the dying bird.
To ask for help for the dying bird.

March 20, 2035 There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would like forever, but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly, the life expectancy for seniors hasn't improved that much. Basically, you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So, do the anti-aging drugs work? Well,it is too early to tell. But the sales so far are very good. April 19, 2035 Of the total US population of 378 million, people over 65 years of age now make up 20% for the first time. The senior ratio of only 4.1% by year 1900, and 12.4% 30 years ago. The number of people above 65 compared to those of what is considered working ages, between 15 and 64, is currently 33.7%. This is up from 18.5% since year 2005, which means that for every retired person there are now two workers, compared to four workers 30 years ago. The number of people above the age of 80 has grown to 23.8 million, making them 6.3% of the total population compared to 3.6% in 2005. April 12, 2040 Although introduced in the market only five years ago, 10% of all hydrogen fuel now sold in the US is of the environmentally friendly Re-Hydro label, produced through eletrolysis based on a source of 100% renewable energy. Several producers have turned to producing Re-Hydro, mainly because of lower tax, which also keeps the price of Re-Hydro on the same level as regular hydrogen. Most analysts believe that Re-Hydro will be the dominating fuel in the future. Question: The sales of the life extension drugs so far clearly show that _ . - people have no faith in them - people want to give them a try - they work very well for seniors - they have no effect on people's health
people want to give them a try

Q: Read the following article and select the best answer. Article: "I don't believe in Santa Claus!" Trogmire announced. Tremor looked shocked. "Why not?" he asked. "Because he never leaves me any gifts at all," Trogmire growled. Tremor thought about the evidence for a few seconds. "Maybe," he suggested, "it's because when Santa checked his list, your name wasn't in the 'nice' column." "So, he could at least bring me a lump of coal!" Trogmire replied. "And," he went on, "Troubled doesn't believe in Santa, either." "Right," Tremor said, "because he saw his parents putting the 'From Santa' presents under the tree. But I know the truth about that. My mother found out from Troubled's mother. When Troubled's parents got an e-mail from Santa, saying that he would never bring Troubled another gift, they didn't want to tell him the truth. So now they buy presents and pretend they're from Santa." "What did Troubled do to get Santa so mad?" Trogmire questioned. "I think it had something to do with the time he put glue paper all over the living room floor on Christmas Eve, and left a sign that said, 'Trapped like a rat!' hanging over the fireplace." said Tremor. "I guess Santa doesn't have a sense of humour," sighed Trogmire. "Well, at least I'm not the only one who Santa scratched off his name list." Question: Why doesn't Santa leave presents for Trogmire or Troubled? - Their parents won't let him leave gifts. - He can't find their homes. - He often forgets their names. - They have behaved badly.
A: They have behaved badly.

Q: Read the following article and select the best answer. Article: Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health. Question: The text mainly discusses the relationship between _ . - heart problems and air quality - heart problems and exercising - heart problems and smoking - heart problems and fatty food
A: heart problems and air quality
