While learning the science lessons, I used to get a doubt--why ear, nose, tongue and eyes should be called as special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connectivity. Interestingly, our hearing is less sharp after we eat a heavy food. Isn't it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a meal, but the hearing pitch does change after a heavy meal. We usually give credit of the taste to our tongue, but do you know that unless saliva dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something. Women are much better smellers than men. They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample. We all can store almost 50,000 different smells, which are strongly tied to the memories. Pupils do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make their vision less clear. Each and every one of us has a particular or individualistic or characteristic smell, which is unique to us, except the twins. This smell is very subtle yet can be sensed even by a newborn. It may be due to this smell that the newborn recognizes the presence of his parents around. What may happen after you have had a rich lunch? A) Your eyes become weak and can not see well. B) You may feel energetic and fresh. C) Your hearing pitch may be decreased. D) Your tongue may lose the function of taste.

Mary Somerville was born in 1780 in Burntisland, Scotland. Her contribution to mathematics was in both algebra   and differential and integral calculus  .     Mary was one of the world's first famous female mathematicians. She became interested in mathematics and decided to study it at the time when it was considered unacceptable for a woman to do so. She bought books on algebra and geometry and read them at night. In spite of disapproval from people around her, she firmly went on with her struggle to learn. She won a prize for her solution to an algebra problem. She went on to write several books on mathematics. Later in her life, she thought deeply about the years in which she had persevered   almost without hope and said, "It taught me never to lose heart."  Mary's way of learning remains useful today. If she worked for a while on a problem without coming up with an idea, she stopped working and turned her attention to the piano, her needlework, or a walk outdoors. She then returned to the problem with a fresh mind and a solution turned up. If she could not understand a passage while reading, she would forget about it and read on; several pages later, the meaning of the puzzling passage would become clear to her. Why did Mary decide to study math? A) Because she found math interesting and wanted to study it. B) Because she was one of the world's first famous female mathematicians. C) Because it was not considered acceptable for a woman to study math. D) Because she was bored and had nothing to do.

Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates  all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a highprotein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet. Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it's possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans. It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds----and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. "The studies are generally far too short to tell effect," Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, "It makes no real difference which of the weight-loss ways one chooses." According to Wycherley's analysis, dieters should take in more   _  . A) fat B) carbohydrates C) protein D) calories
