Article: Through a series of experiments an American scientist has gained an understanding of the social structure of the most complex of ant societies. The ants examined are the only creatures other than man to have given up hunting and collecting for a completely agricultural way of life. In their underground nests they cultivate gardens on soil made from finely chopped leaves. This is a complex operation requiring considerable division of labour. The workers of this type of ants can be divided into four groups according to the size. Each of the groups performs a particular set of jobs. The making and care of the gardens and the nursing of the young ants are done by the smallest workers. Slightly larger workers are responsible for chopping up leaves to make them suitable for use in the gardens and for cleaning the nest. A third group of still larger ants do the construction work and collect fresh leaves from outside the nest. The largest are the soldier ants, responsible for defending the nest. To find out how good the various size-groups are at different tasks, the scientist measured the amount of work done by the ants against the amount of energy they used. He examined first the gathering and carrying of leaves. He selected one of the size-groups, and then measured how efficiently these ants could find leaves and run back to the nest. Then he repeated the experiment for each of the other size-groups. In this way he could see whether any group could do the job more efficiently than the group normally undertaking it. The intermediate-sized ants that normally perform this task proved to be the most efficient for their energy costs, but when the scientist examined the whole set of jobs performed by each group of ants it appeared that some sizes of worker ant were not ideally suited to the particular jobs they performed. Question: The organization of the ants has the effect of _ . Yes or no, is the answer "dividing the work up systematically"?
No

Article: We all know that when leaves fall to the ground they die and become food for worms. When worms pass the leaves, their waste can help to make the soil rich, from which the plants use to get their nutrition. The plants grow and provide food for animals. When the animals eat the plants, their waste goes back into the soil. It's a perfect cycle. But at the Elephant Conservation Centre in Lampang, Northern Thailand, they are using elephant waste for something more--to make 100% natural, beautiful color1ful paper products! 100 years ago over 100,000 elephants in prefix = st1 /Thailandworked on farms, building sites and even in the army. However, only 6,000 remain there today because of advances in technology that have made elephants' old word less necessary. Elephants are doing new jobs now, including entertaining tourists by painting and playing football, and now by helping in the paper making industry. And their keepers, called Mahouts, can earn a living for their families and help their elephants by using elephant waste, also called "dung" to make beautiful, natural, paper products without any bad smell. Every day an adult elephant eats about 200kg of plants like bamboo, grass and watermelon seeds. His body system breaks the plants into 50kg of fibers, which can produce 115 sheets of fibrous paper. The first step to make this special natural paper is to collect the fiber rich "dung" from the elephant. The next step is to wash it and boil it for five hours to kill bacteria. (The water the use in this process is reused to water plans at the Centre, which, in turn, feed the elephants). After it's boiled, they cut fibers up. During the cutting process, they add in the desired color1 of the paper. For the fourth step, they take the mixture and make balls of 300g. Each ball is then speeds lightly over bamboo frames to dry into one large sheet of paper. After a few hours in the sun, the sheets are dry enough to remove. The result is a wonderful, 100% natural, recycled paper. People around the world are getting... Question: What are the exact words to describe the whole process of the product? Yes or no, is the answer "Unusual, amazing, and perfect."?

Ques: Article: There comes a time in a person's life when they may realize that their laundry is just not coming out the way that they had hoped for. The whites may not be getting white enough or the color1s might be fading. This can cause you more money if you don't know how to properly do your laundry. These tips are lifesaving tips when it comes to washing your dirty clothes. If you have a habit of throwing all your clothes into the washing machine together, you need to stop now. Washing your clothes in the same load will only cause them to fade onto each other or not become as clean as they could. To save you lots of time, try buying a laundry sorter so that your clothes are already sorted and ready to be throne into the washing machine. Another great advice would be to read the labels on the back of the clothing. The labels are there for a reason and this could help to save you a lot of money in the long run. It makes sense not to wash something in warm water when it specifically says to wash in cold water, if you did you could end up with a shrunken sweater. There are basically five groups that your laundry should be sorted into; whites, lights, darks, bright color1ed clothes, and delicates. The whites are basically anything white like your undergarments and t-shirts. Try not to get the whites and the lights confused. The light color1ed clothes are those that can be white, striped, off-whites, pastels, cream color1ed, etc. Dark clothes are those including blacks, blues, and browns. The reason that this is important is because dark clothes tend to fade onto other clothes and there are also special products like Woolite Dark that you can buy to keep them from fading. It just makes sense to wash these separately. The bright clothes are those that are red, yellow, orange, green, florescent, etc. These clothes can make your other clothes turn color1s. Question: The passage may be written by an experienced _ . Yes or no, is the answer "life coach"?
Ans: No

Article: Digital technology -- email and smart phones especially -- have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it and only 35 percent say it's tolerated. Skeptical bosses will likely have their doubts reinforced by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while "working" remotely, while 35 percent have done housework,and 28 percent have cooked dinner. It is true, however,that working at home makes people much more efficient , because it allows workers to take care of annoying housework while still getting their jobs done. It's much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush. The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker. More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who have worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility to manage their time efficiently. Question: What does the author suggest smart firms do? Yes or no, is the answer "Adopt flexible work patterns."?
No
