PROBLEM: Article: Probably many of you know the idiom "an eye for an eye and a tooth for a tooth". But do you believe a tooth for an eye? That's something a little bit different. This strange exchange is neither a form ofretribution nor an unexpected gift from the Tooth Fairy --- it's actually a very generous gift from a young Irishman, Robert McNichol, 23, to his formerly blind father, 57-year-old Bob McNichol. In 2005, Bob McNichol's sight was destroyed in an accident when his eyes weredoused(......)with liquidaluminum . Doctors predicted that he would never be able to see again. But McNichol never liked to take no for an answer: when he heard about a unique operation called Osteo-Odonto-Keratoprosthesis, he knew he had to _ , even though the success rate was a mere 65 percent. In the technique, the eyesocket is rebuilt and implanted with a human tooth and part of the jawbone, to provide support for an artificialcornea . Luckily for McNichol, Robert was willing to sacrifice one of his teeth to help his father regain his sight. The technique isn't simple: McNichol's first stint on the operating table lasted ten hours, with a five hour follow-up session at a later date. But thanks to his son's gift, he's already seeing astonishing results. "Now I have enough sight for me to get around and I can watch television. I have come out from complete darkness." he told his friends.
Question: Bob McNichol lost his sight _ .
Options: (A) after he had an operation on his eyes (B) because of an accident (C) because he met with a serious traffic accident (D) when he was 57 years old

SOLUTION: B

PROBLEM: Article: How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words. The power of words, then, lies in their association--the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can _ his meaning in words which sing like music and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and impolite.
Question: Where does the real power of the words come from?
Options: (A) From the words themselves. (B) From their characteristics. (C) From their curiosity. (D) From their association.

SOLUTION: D
