Read the following article and select the best answer. Article: Plants are very important living things. Life could not go if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. So animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and _ plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants don't grow from seeds. They grow from spores. Spores are so small and light that they can float in the air. We may say that spores are quite the same as the seeds. When these spores fall on wet and _ , they usually grow into new plants. Question: The main idea of the passage is that _ . - plants are important for life - plants cannot grow without air - there are many plants around us - we cannot live without water
(A).
plants are important for life

Article: SPEAKING in front of groups may not be a big deal for some people, and there are those who probably sail through their careers without ever having to do so.When I was studying for my C.P.A., I was sure that I d be safe.But life isn't predictable.I ended up in a career that depends on public speaking. I ran my own accounting firm for eight years, and in 2009 was co-founder of the American Institute of Certified Tax Coaches, a nonprofit group based in San Diego that educates accountants, lawyers and other tax professionals. Before we started the organization, in fact, I thought I) d better get some practice--but my first talk around that time, in front of group of 200 professional advisers for older taxpayers, with my body trembling all the time, was a fiasco . After that, I decided to _ as many speaking opportunities as possible, to try to become more comfortable with the idea of talking before groups.I knew it wouldn't be easy.I know the material --I've written two books about taxes ?but I am a bit of a perfectionist and rely heavily on notes, which can create a lot of anxiety. I talked to my father about how the magic trick had bombed, and he suggested that I have him criticize me.I gave the same speech to him, without the magic trick.He said that I seemed more nervous when I relied on my notes and that I should speak more from my heart.I've done that ever since, and it has helped. To gain more experience, I still look for speaking opportunities. I speak before various associations, and I started appearing on television news and talk shows a little more than a year ago.I've been on local TV in places like San Diego, Los Angeles, New Orleans and Hawaii. I've made much progress.I've had several audience members come up to me and say they thought my talk was great and that they learned a lot.It' s hard to believe, but some people have asked: u Do you ever get nervous? Because you don' t look nervous at all.You' re such a natural at this. Question: The writer's first talk in public failed because _ . - he was not familiar with the topic - the audience didn' t understand him - he was shy and miss the key points - he was too nervous to express himself well
(A).
he was too nervous to express himself well

Read the following article and select the best answer. Article: Among the more color1ful characters of Leadville's golden age were H.A.W.Tabor and his second wife, Elizabeth McCourt, better known as "Baby Doe". Their history is fast becoming one of the legends of the Old West. Horace Austin Warner Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here." he said. As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco.It was his custom to "grubstake" prospective miners, in other words, to supply them with food and supplies, or "grub", while they looked for ore , in return for which he would get a share in the mine if one was discovered. He did this for a number of years, but no one that he aided ever found anything of value. Finally one day in the year 1878, so the story goes, two miners came in and asked for "grub". Tabor had decided to quit supplying it because he had lost too much money that way. These were persistent, however, and Tabor was too busy to argue with them. "Oh help yourself. One more time won't make any difference," He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in return for which they gave Tabor a one-third interest in their findings. They picked a barren place on the mountain side and began to dig. After nine days they struck a rich vein of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine," made $1,300,000 for Tabor in... Question: The underlying reason for Tabor's life career is _ . - purely accidental - based on the analysis of miner's being very poor and their possibility of discovering profitable mining site - through the help from his second wife - he planned well and accomplished targets step by step
(A).
based on the analysis of miner's being very poor and their possibility of discovering profitable mining site
