Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: ScienceDaily (July 5, 2009) -- Researchers from the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb , which enables it to harvest 16 times the amount of water collected by other plants in the Negev Desert. This is the first example of a self-irrigating plant worldwide. The desert rhubarb grows in the mountains of Israel's Negev desert, where average rainfall is particularly low (75 mm per year). Unlike most of the other desert plant species, which have small leaves so as to reduce water loss, this plant is unique in that its leaves are particularly large; each plant's rosette of one to four leaves reaches a total diameter of up to one meter. Prof. Simcha Lev-Yadun, Prof. Gidi Ne'eman and Prof. Gadi Katzir came across this unique plant while studying the field area with students of the Department of Science Education-Biology of the University of Haifa-Oranim, and noticed that its waxy leaves are unusually large. They observed an exceptionally ridged structure on each leaf. The scientists explained that these deep and wide depressions in the leaves create a "channeling" mountain-like system by which the rain water is channeled toward the ground surrounding the plant's deep root. Other desert plants simply absorb the rain water that goes through the ground in its immediate surroundings. The desert rhubarb is able to harvest quantities of water that are 16 times the amount of water harvested by the small-leafed plants of the Negev desert region. When the research team watered the plant artificially, they observed how the water flows along the course of the leave's depressions to the ground surrounding the plant's single root and then goes through the ground to a depth of 10 cm or more. Under the experimental conditions, water goes through the ground only as deep as 1 cm. "We know of no other plant in the deserts of the world that functions in this manner," the researchers concluded. Options: A enables it to survive with fewer leaves B works in many other desert plants in the world C helps it collect much more water than other plants D prevents the plant from losing water and heat Answer: C helps it collect much more water than other plants Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: If you have ever been sad because of failure,please remember,for often,achieving what you set out to do is not the most important thing. A boy decided to dig a deep hole behind his house.As he was working,a couple of older boys stopped by to watch."What are you doing?" asked one of the visitors."I want to dig a hole all the way through the earth!" the boy answered excitedly.The older boys began to laugh,telling him that digging a hole all the way through the earth was impossible.After a while,the boy picked up a jar.He showed it to the visitors.It was full of spiders,worms and other insects.Then he said quietly and confidently,"Even if I can't dig all the way through the earth,look what I found along the way!" The boy's goal was far too difficult,but it did cause him to dig.And that is what a goal is for--to cause us to move in the direction we have chosen,in other words,to cause us to dig! Not every goal will be fully achieved.Not every job will end successfully.Not every dream will come true.Not every love will last.But when you fall short of your aim,maybe you can say,"Yes,but look what I found along the way!Look at the wonderful things which have come into my life because I tried to do something!" It is in the digging that life is lived.And I believe it is joy in the journey that really matters. Options: A brave B impolite C foolish D warmhearted Answer: C foolish Question:

A: The older boys laughed at the boy because he was thought to be _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: it tastes just chicken Away from home, eating is more than just a way to keep your stomach full.It is a language all its own, and no words can say, "Glad to meet you ...glad to be doing business with you ..." quite like sharing a meal offered by your host. Clearly, mealtime is not the time for you to say, "Thanks, but no thanks." Acceptance of the food on your plate means acceptance of host, country, and company.So, no matter how difficult it may be to swallow, swallow.Or, as one experienced traveler says, "Travel with a cast-iron stomach and eat everything everywhere." Often, the food offered represents proudly your host country's eating culture.What would Ataiericans think of a French person who refused to take a bite of homemade apple pie or sirloin? Our discomfort comes not so much from the thing itself; it comes from our umamiliarity with it.After all, an oyster has remarkably the same look as a sheep's eye; and a first look at a lobster would remind almost anybody of a creature from a science fiction movie, not something you dip in butter and eat.By the way, in Saudi Arabia sheep's eyes are a famous dish and in parts of China it's bear's paw soup. Can you refuse such food without being rude? Most experienced business travelers say no, at least not before taking at least a few bites.It helps, though, to slice any item very thin.This way, you minimize the taste and the reminder of where it came from.Or, " Swallow it quickly, " as one traveler recommends."I still can't tell you what sheep's eyeballs taste like." As for dealing with taste, the old line that "it tastes just like chicken" is often thankfully true.Even when the "it" is really rat or snake. Another useful piece of advice is not knowing what you are eating.What's for dinner? Don't ask. Avoid glancing into the kitchen or looking at English-language menus.Your host will be pleased that you are eating the food he offers, and who knows? Maybe it really is chicken in that soup. Options: A introduce unfamiliar food B share the writer's personal experiences C suggest ways to overcome a cultural barrier D advise on how to politely refuse to eat foreign food Answer: C suggest ways to overcome a cultural barrier Question:
A:
The purpose of the article is to _ .
