I'm taking a test and have to guess the right answer to the question after the article. Article: The way we get about has a deep influence on the way we live-affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true? Personal Air Travel The idea: flying cars Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people. You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car. Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down. Flying for Fun The idea: Jet Packs The idea was a hit when a stuntman flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful. You'll be able to use the equipment-roughly the size of two scuba tanks fastened to your back-for short journeys. They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping. Taxis The idea: driverless taxis These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go. For the price of one person's bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents. There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards. The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus. Question: We learn from the passage that flying cars _ . Options: A: will operate only in the sky B: will be more expensive than common cars C: will have few bad effects on the environment D: won't be equipped with things similar to what cars have

I'm taking a test and have to guess the right answer to the question after the article. Article: Sweet peas, cucumbers, grapes ---- what do you think they have in common? None of these vegetables grow on trees. They all don't have strong roots, big trunks or long branches, which makes it harder for them to get sunlight. But don't worry. They have developed their own unique way of growing taller climbing! Take sweet peas as an example. The plant grows as a straight stem until it finds something to hold onto, either a nearby tree or a stick. That is when the stem makes small coil that helps the plant hold the stick tightly. How these plants are able to do this has been a mystery to scientists for years. Even Charles Darwin was interested in this question. But it is not until now that a Harvard research team has finally found the answer. The study was published in the Journal Science earlier this month. The key, as it turns out, is inside a kind of thread-like cell called "g-fiber cell", which has the ability to shrink or stretch. Each stem of the pea plant is made of several layers of g-fibers. Once the plant finds something to hold onto, cells on side of the stem start to shrink, forcing the whole thing to bend and coil, which is a bit like how our muscles get our bodies to move. What's more, a pea's coil is not exactly like that of a spring. If you look closely, you may find that a spring coils all in the same direction, but a plant's coil is in two opposite directions, like a telephone line. This means that the stem can stay soft when pulled gently but become strong enough when pulled harder. "You want the plant to have a little bit of flexibility so that if the wind blows or an animal disturb it, it doesn't break," explained Sharon Gerbode, author of the study. "This structure allows the plant to easily accommodate small movement, but then if something really serious happens it can become strong and protect itself." Question: What's the purpose of the writer in the passage? Options: A: To tell us why the sweet peas can climb the tree or stick. B: To display new research allows scientists to understand more about climbing plants. C: To show us new scientific research about the role of "g-fiber cell". D: To tell us the mysterious natural phenomena of some plants.

I'm taking a test and have to guess the right answer to the question after the article. Article: How to Memorize Things Quicker Than Other People? The following is my advice for you. Step 1: Preparation To improve your memorization, pay close attention to which environment you choose. For most people, this means choosing an area with few distractions, though some people do advance greatly by learning in public areas. Figure out what is most conducive to your learning so that you can get started. Next, start drinking some tea. I could link you to many scientific studies that confirm green tea as a natural catalyst for improving memory. Mechanically speaking, our ability to recall information comes down to the strength between neurons in our mind. The more you exercise the repetition, the stronger it is, resulting in the ability to memorize. As we get older, poisonous chemicals will damage our neurons, leading to memory loss. Green tea contains compounds, however, that block this poison and keep your brain cells working properly a lot longer. Step 2: Record what you're memorizing This is especially useful if you're trying to memorize information from a lecture. Use a tape recorder to track all of the acquired facts being spoken and listen to it. If you're trying to memorize a speech, record your reading of the speech and listen to the record. Obviously, this is most helpful for auditory learners, and it's also useful because it ensures that you're getting more context from a lecture that will help you learn the information faster. Step 3: Write everything down Before you start trying to recall everything from memory, write and re-write the information. This will help you become more familiar with what you're trying to memorize. Doing this while listening to your tape recorder can also help you keep a lot of the data. This is most useful for experiential learners. Step 4: Section your notes. Now that you have everything written down in one set of notes, separate them into sections. This is ideal for visual learners, especially if you use color1 coding to distinguish between subjects. This will help you... Question: For auditory learners, to memorize better and faster, what is the most important? Options: A: To record themselves reading aloud and listen to themselves speaking. B: To track all of the acquired facts being spoken and listen to it. C: To get more contexts from a lecture and learn the information faster. D: To record and listen to what they're to memorize.
