user: Question: Read the article and select the best answer. Article: Plants need green leaves to make food. A plant needs sunlight and carbon dioxide  from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells   in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins   can't carry all this sugar away, so the leaves change the sugar into starch  , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem   and in leaves, fruits and seeds. Question: Food is stored in roots or stems in the form of   _  . Options: A: sugar B: starch C: water and salts D: carbon dioxide

Question: Read the article and select the best answer. Article: Most people agree that it's important to have a sense of humour. Having the ability to laugh can help one overcome anxiety, and make better decisions in difficult situations. People with a well-developed sense of humour appear to be happier, and some are healthier as well. This suggests that having a sense of humour is good for you. Humourless people may find themselves being treated as a fool, and become anxious and upset. A sense of humour also plays an important role in human relationships. However, not everyone has a sense of humour. People with developmental disabilities   can sometimes have no sense of humour, or have a very strange one. A number of factors affect a person's sense of humour, with the age probably being the main one. Young children are often highly amused by simple jokes or shows, while teenagers prefer to enjoy the ironic   events. Educational level, culture, and religious faith also affect one's sense of humour. While Christians, for example, may have a deep appreciation of jokes about the Bible, others may find them disrespectful. Many people believe that a sense of humour is something that develops on its own, and that you cannot teach someone to understand why jokes, certain comments, situations or events are funny. However, things can be done to one's sense of humour. Children, for example, benefit from being told jokes and encouraged to laugh, although some children's jokes might seem rather strange to adults. If you have children, try to encourage them to tell jokes and think about what makes things funny. And it will help them develop a sense of humour. Question: According to the passage, which of the following doesn't influence one's sense of humour? Options: A: Culture. B: Age. C: Educational level. D: Family backgrounds.
