Article: A long time ago, in an Italian city, the people there built a tower which was admired by everyone passing through. A little further down the road, in a neighboring city, they had built a tower of similar beauty. The two towers were equally well known. The people of the second city, envious and filled with pride, planned to destroy the neighboring tower so it wouldn't take attention away from their own. One night, they came to the tower and began to quietly its foundations . The next morning, the tower was leaning slightly ,but nobody noticed. The same happened for the following few days, until a little girl who was passing by pointed up at the tower and said: " I think the tower is going to fall down." And everyone around looked closely, and could see that she was right .Nervousness spread through the city. And they tried many methods to try to straighten the tower, but nothing seemed to work. That was, until one day when the same little girl was walking up again, and she put her arm on the side of the tower to rest. She felt the tower shaking slightly. When she took her hand off it, the movement stopped. And when she put it back on again, the same thing happened. The girl spent a while doing this, until she was completely certain of what she had discovered: " The tower is ticklish ( ) !" She ran to get some plants, and she planted them right next to the tower. Now if the tower leant over any further it would be tickled by the leaves of those plants. Being a ticklish tower, it would then return to where it had been. In this way, the girl managed to make sure that the tower didn't fall down, but still kept it leaning a little. The fact that it was leaning made it even more famous, and this taught a fine lesson to the envious people of the neighboring city.
Question: Why did the people of the second city plan to destroy the neighboring tower?
Options: (A) Because the tower blocked the way of their tourists. (B) Because the tower had the same building style as theirs. (C) Because they hoped that the tower could lean slightly. (D) Because they hoped that visitors just liked their own tower.

Article: As the nights get lounger, those who suffer from the winter blues will be planning ways to escape to the sunshine. But there may be a much simpler way of cheering yourself up... simply shining a bright light into your ear canal. Up to one in four Britons suffer from seasonal affective disorder, with seven per cent of the population having full-blown SAD. It is caused by the brain not receiving enough daylight which is needed to trigger serotonin , a hormone that regulates mood. Symptoms range from mild lethargy to depression and insomnia, but a cure might be in sight. Two clinical trials, run by Valkee - who make a device that can shine light into your ear - and the University of Oulu in Finland, have found that carefully targeted light can help prevent the condition. Juuso Nissila, Valkee's co-founder and chief scientist said: "We presented earlier that the human brain is sensitive to light". "These two clinical trials demonstrate that channeling bright light via ear canal into brain's photosensitive areas effectively prevents and treats seasonal affective disorder." The University of Oulu reported that in their first study, 92 per cent of the patients with seasonal affective disorder achieved full remission after a month of daily eight-to-12 minute doses of light from the Valkee. Time Takala, chief physician at the Oulu Deaconess Institute said: "These two trials show that bright light channeled into the brain via ear canal is an important future method to treat seasonal affective disorder." Valkee launched its bright light headset in August 2010. It is classed as a medical device under EU regulations. The device channels bright light direct to the brain via the ear canal to prevent and cure depression, mood swings and even circadian-rhythm disorders such as jet lag. It costs PS185 and looks like an iPod - only the earphones emit light rather than sound.
Question: How many Britons suffer from seasonal affective disorder?
Options: (A) Approximately a quarter. (B) 7%. (C) More than one fourth. (D) 92%.

Article: Healthy relationships are fun and make you feel good about yourself. The relationships that you make in your teenage years will be a special pan of your life. They will teach you some of the most important lessons about who you are. This may help you understand different kinds of relationships, what makes each relationship special, and how to communicate in a positive way. What makes a relationship healthy? Communication and Sharing: The most important part of any healthy relationship between two people is being able to talk and listen to each other. You and the other person can find out what your common interests are. You can share your feelings with the other person and trust that he or she will be there to listen to you and support you. In healthy relationships, people don't lie. Communication is based on honesty and trust. By listening carefully and sharing your thoughts and feelings with other people, you show them that they play an important part in your life. Respect and Trust: In healthy relationships, you learn to respect and trust important people in your life. Disagreements may still happen, but you learn to stay calm and talk about how you feel. Talking calmly helps you to understand the real reason for not getting along. It makes it much easier to figure out how to fix it. In healthy relationships, working through disagreements often makes the relationship stronger. In healthy relationships, people respect each other for who they are. This includes respecting and listening to yourself and your feelings so you can set boundaries and feel comfortable. You will find that you learn to understand experiences and feelings of others as well as having them understand your experiences and feelings. How do I know that I have a healthy relationship with someone? You know that you are in a healthy relationship with someone because you feel good about yourself when you are around that person. Unhealthy relationships can make you feel sad, angry, scared, or worried. Healthy peer relationships involve an equal amount of giving and taking in the relationship. In unhealthy relationships, there is an unfair balance. You may often feel that you are giving the other person more attention than that he or she gives to you. You should feel safe around the other person and feel that you can trust him or her with your secrets. In a healthy relationship, you like to spend time with the other person, instead of feeling that you have to spend time with him or her.
