Write a multi-choice question for the following article, with the given choices and answer: Article: Buffet is the son of the best investor Warren Buffet, and he's the CEO of a philanthropic foundation . But he's also a lifelong farmer. He is familiar with the saying that each farmer can expect to have 40 opportunities to improve their harvest. And it's not just farmers who know there's a clock running on their efforts. " We all need to recognize that we only have a fixed amount of time to affect change," said Howard G. Buffett(HGB) HGB wants to invest more than $3 billion, in an effort to end global hunger and poverty for the world's nearly one billion poor people by 2045. He's decided to focus much of his effort on farming in the developing world. He believes that the best way to deal with poverty is to change the lives of farmers in the poorest nations on the planet. "It's a pretty well proven fact that nothing works better at bringing people out of poverty than investment in rural areas," said HGB. Healthy soils are a most important part of productive farmers, but 1.5 billion people -- a fifth of the global population -- live on poor land. "You have to fix the soil," he said. HGB also has the idea that farmers who own their own land will raise crops with an eye to the long-term health of the soil. He would like to see that balanced with a foreign-aid plan. HGB notes that too often, experts want to make agriculture in developing nations look like farming in rich countries." It's not going to happen like that," said HGB. "You need to consider local differences, local culture." Many more ideas of HGB can be found in his new book, Forty Chances: Finding Hope in a Hungry World. Options: A 1.5 billion B One fifth billion C 6 billion D 7.5 billion Answer: D 7.5 billion Question:
Ans: What's the population of the whole world?

Write a multi-choice question for the following article, with the given choices and answer: Article: Developing healthy eating habits starts from childhood, therefore it is important for parents to teach and provide children with a healthy diet. DPHSS administrator of the Bureau of Nutrition Services, Charlie Morris told KUAM News, "A healthy diet for a child consists of a lot of fruits and vegetables in the diet limiting the amount of simple sugars in the diet and high fat food and highly processed food." This means staying away as much as possible from food such as chips, cookies, candies and sugary drinks, as all children need to have meals which involve a well-balanced diet. Community nutritionist Thelma Romoso said, "The fruit, the vegetable, the grain, the protein, and also the milk, the diary product, so for the fruits it's easy for a mother to go into the two plus three concept of fruits and vegetables or five a day." This concept means that there are at least two servings of fruits a day, three servings of vegetables a day which can be served for lunch and dinner. As for protein parents can make a variety of dishes from chicken, beef, fish or even dried beans to pledge the child gets three servings a day. Morris said that the child's hunger level controls how much is eaten and the parent controls what and when the meal is offered, saying, "Mom needs to ensure that the food offered is good food for the child to eat and throughout the day depending on how active they are, snacks are not a bad thing, so the mom should offer good kinds of snacks." When it comes to preparing your child's lunch and snacks for school, make sure to keep in mind that the food you provide should not only be a source of energy but also be nutritionally beneficial such as fresh fruits, and whole grain bread. But parents must be sure to remember that a good nutritional diet must be balanced with physical activity, namely it is important that children get outside and run around and play and get activity in addition to eating a good diet. Options: A mothers should prepare delicious food by themselves B highly processed food should be reduced in daily life C sugars and high fat exist in few kinds of food D active children prefer more and more snacks Answer: B highly processed food should be reduced in daily life Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Many of us believe that a person's mind becomes less active as he grows older. But this is not true, according to Dr Jarvik, professor of _ at the University of California. She has studied the mental functioning of aging persons for several years. For example, one of her studies concerns 136 pairs of twins , who were first examined when they were already 60 years old. As Dr Jarvik continued the study of the twins into their 70s and 80s, their minds did not generally decline as was expected. However, there was some decline in their psycho-motor speed. This means that it took them longer to finish mental tasks than it used to. But when speed was not a factor, they lost very little intellectual ability over the years. In general, Dr Jarvik's studies have shown that there is no decline in knowledge or reasoning ability. This is true not only with those in their 30s and 40s, but with those in their 60s and 70s as well. It is true that older people themselves often complain that their memory is not as good as it once was. However, much of what we call "loss of memory" is not that at all. There usually was incomplete learning in the first place. For example, the older person perhaps had trouble hearing, or poor vision, or was trying to learn the new thing at too fast a speed. In the cases where the older person's mind really seems to get worse, it is not necessarily a sign of decline due to old age. Often it is simply a sign of a sad emotional state. Options: A a worsening state of health B old age C nervous tension D a state of unhappiness Answer: D a state of unhappiness Question:
Ans: More often than not, what we call mental decline is actually a sign of _ .
