TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
PROBLEM: Article: You might think that whether you choose a blue shirt or a yellow one to wear to work or college makes no difference to your day and those around you. However, an increasing number of experts argue that the colors we choose affect our mood , our career and even our health. Color affects us to a greater degree than most of us realize. Color is used increasingly by doctors for influencing mood and state of mind, and for various types of medical treatment. Green is a good color if you are not feeling well, and possibly this is why we sometimes give flowers and plants to friends and relatives in hospital. It is also thought that turquoise , a "user-friendly" color, can treat stress and headaches. Companies use color to encourage us to buy their products. For example, purple, which mixes well with red, is used to show that a company has new ideas and the power to make them happen. Orange and blue are also recommended colors for companies to use, because orange is the color of communication and blue suggests safety. So this could be a particularly good combination. Companies have found that certain colors "speak" to specific age groups. They often use red to attract younger people to their products, for example, as it is lively and more youthful than colors like gold and navy , which older customers seem to prefer. Wearing different colors can affect how you feel and how others react to you, so it is important to consider this when deciding what to wear in the morning. If you want people to take you seriously, then wearing navy or black is good. Blue would also be helpful for an interview or oral examination because it relaxes you and makes you feel calm. Red gets you noticed by everyone and makes you feel energetic, but be careful, as it can raise your pulse rate and not everyone wants this effect. So think carefully before you leave the house or visit a friend with a gift. The colors you choose in both cases are a powerful tool. Are you making the right impression-- on yourself and on others?
Answer: is good for health

SOLUTION: Turquoise is a color that _ .

PROBLEM: Article: A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk. Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma . They said that they found _ in studies that had reported associations between sunscreen use and higher risk of melanoma. Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence faster than any other cancer in the United States. But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning. The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--people with fair skin and freckles , for example--are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often. The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
Answer: are more in danger of skin cancer

SOLUTION: People with fair skin and freckles _ .

PROBLEM: Article: How men first learned to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken, or written in letters we call words. The power of words, then, lies in their combinations - the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases. Great writers are those who not only have great thoughts, but also express these thoughts in words which appeal powerfully to our minds and feelings. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and rude.
