Read the following article and select the best answer. Article: Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people's behavior, judgment and they might contain important hidden truths as well. "Psychologists' explanations of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insightinto themselves and their world," said a lead author of the study Carey Morewedge, an assistant professor at Carnegie Mellon University. In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing the hidden truths about themselves and the rest of the world. In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situation that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would. Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew. The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked. "In other words," said Morewedge, "people attribute meaning to dreams when it corresponds (......) with their pre-existing beliefs and... Question: . Which kind of dream is seen as more meaningful than the rest? - A pleasant dream about a person the dreamer likes. - A pleasant dream about a person the dreamer dislikes - An unpleasant dream about a person the dreamer likes. - An unpleasant dream about a person the dreamer dislikes.
An unpleasant dream about a person the dreamer dislikes.

Question: Read the following article and select the best answer. Article: As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air. It also collects bits of dust and microbes that are floating in the air. When the rain reaches the ground it begins to pick up more dust and dirt. Many kinds of mineral substances dissolve in the water. Sand and mud cannot dissolve in water. Since water is so important to us, it is very important that the water we use should be clean. Otherwise, we might get some of the diseases that are carried by water. Many microbes are harmful. They are so small that we cannot see them. These microbes must be removed or killed before the water is suitable for drinking. For example, microbes of diseases like cholera live well in water. If the water supply is not clean, people who drink this water may get these diseases. Thus, to provide people with clean water, the government purifies the water. Purification is a long process and includes three stages: storing, purifying and distributing . The first stage is storing. Man-made lakes are used for this purpose. Water from the rains, other lakes, streams and rivers is collected in the lakes. This water is usually dirty and muddy. In the second stage, water from the man-made lakes is filtered in a special pond. Stones, sand and other unwanted tiny things are caught in it. After that, tiny microbes are still present in the water. These microbes are removed by "airing" the water and by adding a chemical substance called chlorine to the water. This kills all the microbes in the water. After this, the water can be safely used for drinking. The third stage is the distribution of the purified water to homes, hospitals, offices, factories and other places. This is done through a network of pipes of various sizes. These pipes must be made of a suitable material. Question: What is the purpose of adding chlorine to the water? - to air the water - to catch tiny things - to kill tiny microbes - to remove harmful gases
Answer:
to kill tiny microbes
