Article: NOT all math skills are learned in the classroom. Some of them come naturally. Consider the split-second calculations you make when you estimate the number of empty seats on the school bus or the number of cookies in a cookie jar. These estimates can often be done without counting. That's because humans are born with the ability to closely guess the number of items in a group. Researchers call this ability a person's "number sense". To see how a person's inborn number sense might be linked to mathematical performance in the classroom, psychologist Justin Halberda and his colleagues from Johns Hopkins University in prefix = st1 /Baltimore,USran some tests. The scientists asked 64 14-year-olds to look at images of yellow and blue dots that flashed on a computer screen for a fraction of a second. Each image contained between 10 and 32 dots that varied in size. Some images contained twice as many blue dots as yellow dots. In other images, however, the number of blue and yellow dots was nearly equal. For each image, the students were asked to estimate which color1 had more dots. The scientists found a wide variation in how well students could pick the color1 with the most dots. The scientists then looked at the students' math scores dating back to kindergarten. Children that performed best in the image test also scored the highest in standard math tests. The same finding held true at the other end of the spectrum . Students who didn't score well on the image test received lower math scores. The study was the first to show a link between a person's inborn number sense and his or her achievement in formal math training. Does this connection mean that one cannot be good in math if they have a weak number sense? Or that having a strong number sense is a guarantee for good grades in math? The answers are not clear. While scientists continue looking at the possible links between a person's number sense and math achievement, one thing is certain: Doing lots of math homework will _ your chances of success.
Answer: Those who have a strong number sense are sure to do well in math.
answer:
Which of the following is not true according to the passage?

question:
Article: Years ago a farmer owned land along the Atlantic. He constantly advertised for hired hands. Most people were not willing to work on farms along the Atlantic because they worried about the terrible storms that destroy buildings and crops. The farmer received a steady stream of refusals at the interview for a farmhand Finally, a short, thin man approached the farmer. "Are you a good farmhand?" the farmer asked him. "Well, I can sleep when the wind blows. " answered the little man. Although puzzled by this answer ,the farmer, desperate for help, hired him. The little man worked well around the farm ,busy from dawn to dusk, and the farmer felt satisfied with the man's work. Then one night the wind howled loudly from offshore. Jumping out of bed,the farmer grabbed a lantern and rushed next door to the hired hand's sleeping quarters. He shook the little man and yelled, " Get up! A storm is coming! Tie things down before they are blown away! " The little man rolled over in bed and said firmly, "No sir. I told you, I can sleep when the wind blows. " Enraged by the response, the farmer was tempted to fire him on the spot ,Instead, he hurried outside to prepare for the storm. To his amazement,he discovered that all of the hay had been covered. The cows were in the bam,the chickens were in the coops,and the doors were barred The shutters were tightly secured. Everything was tied down, Nothing could be blown away. The farmer then understood what his hired hand meant, so he also returned to his bed to sleep while the wind was still blowing.
Answer: Because he offered poor conditions for the hired hands.
answer:
Why did the farmer constantly advertise for hired hands?

Article: An average 30-year-old person who has eaten three meals a day since birth has eaten more than 30,000 meals to date. Even if you've only eaten half that much, you have to admit this: you've let some of that breakfast, lunch or dinner go to waste. And it turns out that we're all to blame for this shaming fact: 30% of all food produced in the world each year is wasted or lost. That's about 1.3 billion tons, according to a new report by the U.N. Food and Agriculture Organization. That's the weight of more than 8.6 million full-grown blue whales, the largest creatures on earth. That's the weight of more than 2.3 million Airbus A380s, the largest planes in existence. That's as if each person in China, the world's most populous country with more than 1.3 billion people, had one ton mass of food they could just throw into the dustbin. It's almost _ ,isn't it? Setting aside that big number, we find the people with the most money are the ones who waste the most. Per capita( ), European and North American countries waste between 95 and 115 kilograms of food. Sub-Saharan African, South Asian and Southeast Asian countries waste much less -- between 6 and 11 kilograms per person. Here's another statistic: all the food that the world's richest countries waste is about equal to all the food that sub-Saharan Africa produces. The numbers: 222 million tons and 230 million tons, respectively( ). Basically, the wasted food of the rich could feed much of the African continent. And these numbers come as we've just been reporting about rising food prices around the world in the past week. And my own personal tip: if I eat at a restaurant and can't finish it all, I ask for a doggie bag. I used to be a waiter years ago and will never forget the amounts of food I saw left on the table after the bill was paid. There's no reason to waste food. It's up to all of us to use our common sense to eat and shop just a bit more wisely.
Answer: About 5.6 billion tons.
answer:
According to the U.N. Food and Agriculture Organization, how much food do people produce each year in the world?
