PROBLEM: Article: They sit by the door waiting for me. And while I may speak more about the narrowness of my very limited life than their real worth, just the fact that they're sitting there, waiting for me, makes me happy. I speak, of course, of my wonderful, brilliant, intelligently designed, calf-high rubber boots. They are a piece of industrial genius . They are real and vibrant , and make my life more worth living. My rubber boots are real and they do not fail me. I slip them on over my socks at a moment's notice. They go on easily. My feet feel joyful like the wagging tail of a dog waiting for its walk. My feet know they are safe. I step outside the house and nothing can stop me--the late season snowstorm, the pool of standing water at the bottom of my doorsteps that will never give off, the mud and dirt this season brings. My feet are warm and dry and happy. And so am I. My boots are modest. They make no promise they can't keep. I found them at one-third the price of the long boots I looked at longingly for years. Mine are American-made and inexpensive and unattractive and brown and solid. They are now three years old and still look new. I know I will have them forever. I will die with them on. They are homely and they are wonderful. My rubber boots make me braver and kinder and more generous. Yes, I will get the mail. Yes, I will get the newspaper. Yes, I will walk the dog. Yes to the garbage. Yes. Yes. Yes. I have rubber boots, good strong rubber boots--and I am not afraid.

SOLUTION: We can infer from the passage that _ .

PROBLEM: Article: Some English words are made up of the same part and have different beginnings and different endings, such as import, export, report and transport. All these words, you can see, have the same "port", which comes from the Latin word, meaning "to carry" or "to move" from one place to another. And according to the bit at the beginning, which we call the prefix, the meaning changes. "Import" means "to carry in" or "to bring into a country"; "export", "ex" means "out of", so this word means "to carry out of the country"; "re" means "back", so the "report" means "to tell somebody, to bring back information to somebody"; "transport", "trans" means "across" and it means "to carry across one place to another". Let's look at the following words: supporter, reporter, importer and exporter. You can see that in this case these words are nouns which are made up of the verbs plus a suffix, thus meaning a person who does this thing. So "supporter" means somebody who supports. A "reporter" is somebody who reports. "Importer" is somebody who imports and "exporter" is somebody who exports, and so on.

PROBLEM: Article: Bamboo flooring is a growing trend in home flooring and is also a great improvement to traditional hardwood floors.It is the most environmentally friendly kind of natural flooring that you can select for your home.It is also a renewable resource,is stronger than steel,and does not suffer from problems as a result of temperature changes. Bamboo is one of the fastest growing plants on earth,and only takes five years to grow to adult form.Bamboo is harvested every five years,and starts to re-grow immediately after being harvested.For this reason,bamboo is a kind of grass,not a tree.Bamboo is hollow but very hard and can stand up to 50,000 pounds of pressure per square inch.
