Scientists looking for new cures often visit traditional healers. They find out what plants are used in healing. Then they look at what the plant contains.

Article: The candidate who is longing for election to the highest office in the United States must be native-born American citizen who is at least 35 years old and who has lived in the United States for at least 14 years. The election course is complicated, and the road to the Oval Office is long. Potential candidates must present papers stating their intention to seek their party's recommendation; delegates then choose from among those running some months later at the national conferences. Before that, however, each state holds a primary election that determines how the state's voters want the party's delegates to vote. Methods of choosing the delegates vary from state to state. At the conferences, there are speeches and often heated discussions. It may take several rounds of voting before delegates can agree on a candidate. On the final day of the meeting, the presidential candidate announces his or her choice for vice president. Election Day, by law, is the Tuesday that follows the first Monday in November. On this day, registered voters may cast their votes for president, vice president, and candidates for other federal state, and local offices. The popular vote, however, does not determine who will be president. The president is chosen by a vote of the Electoral College, a group of 538 citizens from the 50 states and the District of Columbia who are chosen to cast votes for the president and vice president. The rules for choosing electors, as with the delegates, vary. Each state also decides whether its electoral votes must reflect the popular vote. The number of electors in each state is determined by the number of representatives and senators that a state sends to Congress and, therefore, may change every 10 years, depending on the results of the United States census . The winner must get at least 270 of the electoral votes when the Electoral College meets in December of the election year. The election results are not official, however, until the following January, when Congress meets in a joint conference to... Question: Which of the following might be the best title of the passage? Options: A: The Various Ways of Presidential Election in the USA B: The Qualifications for Being the President of the USA C: The Process of the Election for the President of the USA D: The Rules for Choosing Presidential Candidates in the USA

Q: Read the article and select the best answer. Article: Like most people, I was brought up to look upon life as a process of getting. It was not until in my late thirties that I made this important discovery: giving-away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving-away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving-away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in all unexpected form. One Sunday morning, the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post-office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. "Wasn't it you that wrote us that letter a year ago about delivering a special delivery to your home?" I said yes. "Well, you certainly are going to have a box in this post office if we have to make one for you. You don't know what a letter like that means to us. We usually get nothing but complaints." Question: When the author needed a post-office box, _ . Options: A: he had put his name on a waiting list B: he wrote the postmaster a note of appreciation C: many people had applied for post-office boxes before him D: he asked the postmaster to make one for him

Q: Read the article and select the best answer. Article: One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the wonderful works.. A young couple viewing the paintings ahead of me chatted nonstop between themselves. I watched them a moment and decided she was doing all the talking. I admired his patience for tolerating her constant words. Disturbed by their noise, I moved on. I _ them several times as I moved through the various rooms of art. Each time I heard her constant talking, I moved away quickly. I was standing at the counter of the museum gift store doing some shopping when the couple approached the exit. Before they left, the man reached into his pocket and pulled out a white object. He turned it into a long cane and then tapped his way into the coatroom to get his wife's jacket. "He's a brave man," the clerk at the counter said, "Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise his life wouldn't change. So, as before, he and his wife come in whenever there's a new art show." "But what does he get out of the art?" I asked, "He can't see." "Can't see! You're wrong. He sees a lot. More than you or I do," the clerk said, "His wife describes each painting so he can see it in his head." I learned something about patience, courage and love that day. I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life. And I saw the love shared by two people as I watched this couple walk away arm in arm. Question: Which of the following statements is true? Options: A: The husband was doing all the talking when the couple viewed the works. B: The husband tapped his way to the coatroom to get his jacket. C: The husband was considered a brave man by the clerk at the store. D: The husband allowed blindness to change his life.
