Q: Read the following article and select the best answer. Article: Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it's a chance in million. People have made a census ( ) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat. Question: Which of the following ideas is NOT true? - People have found that only a few kinds of flowers are black. - Flowers are easy to be harmed by very high temperature. - Red, orange and yellow flowers can also absorb the light of all wave lengths. - The black flowers cannot protect themselves from sunlight.
A: Red, orange and yellow flowers can also absorb the light of all wave lengths.

Q: Read the following article and select the best answer. Article: Young children from poor families are more likely to consume junk food and fizzy drinks than their richer companions. A study of 1,800 four- and five-year-olds found more than half of those from poor backgrounds drank at least one a week, compared to just four in ten _ kids. They also drank less milk and consumed more fruit juice which is also linked to child obesity caused by high sugar intake . The phenomenon also relates to children who spend more than two hours a day in front of a TV or playing computer games--whatever their social circumstances. A companion study also found children from poor families were more likely to eat chips, sweets and chocolate. Professor Kate Storey said, "when you are looking at that age group, and such a large percentage of very young kids in the study are consuming a large amount of soda ,it is quite concerning. " The researchers carried out the study by surveying the parents of their participants to find out their dietary habits. Professor Storey said, "If you are drinking a lot of soda and fruit juice, they can displace consumption of water and milk, which are important not just for ending thirst, but for developing healthy bones and teeth, and health and wellness in general." Co-researcher Dr John Spence said, "Dietary behavior and intake patterns are influenced heavily by what happens in the first few years with children, and they maintain those patterns throughout childhood and into adolescence ." In addition to basic health education, this study identifies a need in how we are dealing with poverty and recognizing there is more to poverty than simply the number of dollars people have. Professor Storey said that shows how education can make a difference and lead to healthier eating habits, regardless of what is happening at home. "Many families live in places that might not be very healthy for them and, as a result, they make unhealthy food choices. You can start making a difference in different places. It calls for action in multiple settings, schools and communities,... Question: According to the passage, Professor Storey thinks it helpful for children _ . - to drink more coffee - to drink more milk - to drink more soda - to drink more fruit juice
A: to drink more milk

Q: Read the following article and select the best answer. Article: It is now February 7, 2035. The search engine TalkTalk will be open to the public next week and this service will soon be something beyond your imagination. For the first time you can not only talk to the search engine, but you can discuss with it what you are looking for. For example, if you want to know more about the oil price, TalkTalk asks if you want to know the current oil price, the development of the oil price, or news related to the oil price. You say that you want to read news about it and TalkTalk then directs you to your source, or lets you have the latest news related to the oil price in order from the most respectable sources. Compared with other search services that use a certain algorithm to provide data from a search, the artificial intelligence behind TalkTalk is said to easily spot if a certain source is aiming to cheat the searcher. TalkTalk also judges and stores every given reply and discussion, to learn how to give correct answers. TalkTalk is also set to answer questions directly where there is a definite answer. How well this will work in the long run is yet to be seen, but thousands of people have tested TalkTalk and the quality is really good. The first talking search engine saw the light of day more than 30 years ago and was called Speegle. It could read the results from a written search on the Internet, and was mostly for blind people. So far, TalkTalk cannot read the information from a certain source to you by phone, if it is not freely available. There are currently talks to find an arrangement for this, but it would most likely be difficult because of copyright . TalkTalk is available over the Internet and also by phone, even though it only speaks English. There are no plans to add other languages in the near future, most likely because it will cost a lot of money. When you are tired of asking TalkTalk all your questions, just ask, "Where is TalkTalk?" and you will get an answer that will make you leave it with a smile on your lips. Question: What can be inferred from the text? - TalkTalk can read all the information online. - TalkTalk will speak other languages soon. - TalkTalk may have a bright future. - TalkTalk is very expensive.
A: TalkTalk may have a bright future.
