[EX Q]: Article: Can you smell two things at once? This experiment comes from the research of two scientists from Rice University. Denise Chen and Wen Zhou have been experimenting with the science of smell, and have made some very interesting discoveries.                To explore that, you will need two things with strong, characteristic smells and, of course, your nose. The idea is to smell a different smell with each nostril  . Hold one smell very close to your right nostril, and the other smell very close to your left nostril. Then breathe in and pay close attention to what you smell.               What you should find is that one smell will be very strong. After another sniff   or two, the first smell will go away, and you will smell the other smell. Keep sniffing, and the first smell will come back. Instead of smelling the two smells evenly   mixed, they will work in turns, one after the other.               Why? Chen and Zhou found that your sense of smell acts much like your sense of sight. Hold a book in front of your nose, so that your left eye sees things on the left side of the book, and your right eye sees things on the right side of the book. You will find that your sight works in turns, first on the left side of the book and then on the right side. Notice that you can't focus your left eye on one object while focusing your right eye on another object. Your brain jumps back and forth  , paying attention to one and then the other. The same thing happens with your nostrils. If they are smelling different smells, your brain pays attention to one and then the other. 
 Question: Denise Chen and Wen Zhou discovered that   _  . 
 Options: (A) our brain focuses on one thing at a time (B) our two nostrils act differently towards the same smell (C) our nose prefers to smell stronger smells (D) our sense of smell is connected with our sense of sight 
 Asnwer: C
[EX A]: No

[EX Q]: Article: Targeting teens Using the Web makes teens a target. Posting too much personal information for those millions of cyber eyes to see can cause some big problems and can even invite a threat to your life. As Mary learned, not everyone on the Internet is who he or she says they are. Adults will sometimes pose as other teens, posting fake photos and nice messages to gain trust. They use their fake identity to access the personal information of others, such as home address, phone number, or school name. "That's not the most common scenario ", says David Finkelhor, a sociology professor at the University of New Hampshire. "Only 3 percent of teens aged 10 to 18 who use the Internet report being asked to meet offline. But the danger is real. Safety measures Mary's My Space profile is set to "private", which means that only the people she adds under the "friend" category can access her page. She also doesn't have any pictures of herself on her site. The only self-identifying material she has posted is her name, grade, and a list of hobbies. "People can only add me if they know my last name or my e-mail, "Mary says. " I don't want random people to see my profile. I just go online to talk to my friends." Stay safe and have fun online Experts say almost 90 percent of U.S. teens are online. But not everyone knows how to surf the Web in a smart way. With these tips, you can have fun, stay safe, and avoid embarrassment! Pick a safe password. Make sure your password is something that other people won't be able to guess. Use numbers in between letters. "spar123ky" is better than "sparky 123." Pick a safe username. Make sure yours doesn't say too much about you, "Happygirl13" is better than "AliceWaters13." Don't include your name, age, or where you are from. Never tell a stranger your name, school, address, age, birthday, phone number, or friends' names.

[EX Q]: Article: What are feelings for? Most nonscientists will find it a strange question. Feelings justify themselves. Emotions give meaning and depth to life. They exist without serving any other purposes. On the other hand, many evolutionary biologists acknowledge some emotions primarily for their survival function. For both animals and humans, fear motivates the avoidance of danger, love is necessary to care for the young, and anger prepares one to hold ground. But the fact that a behavior functions to serve survival need not mean that. Other scientists have regarded the same behavior as conditioning and learned responses. Certainly reflexes  and fixed action patterns can occur without feeling or conscious thought. A baby seagull pecks  at a red spot on the bill  of its parent. The seagull parent feeds its baby when pecked on the bill and the baby gets fed. The interaction need have no emotional content. At the same time, there is no reason why such actions cannot have emotional content. In mammals that have given birth including humans, milk is often released automatically when a new baby cries. This is not under intended control but it is reflex. Yet this does not mean that feeding a new baby is exclusively reflex and expresses no feeling like love. Humans have feelings about their behavior even if it is conditioned or reflexive. Yet since reflexes exist and conditioned behavior is widespread, measurable, and observable, most scientists try to explain animal behavior by using only these concepts. It is simpler. Preferring to explain behavior in ways that fit science's methods most easily, scientists have refused to consider any causes for animal behavior other than reflexive and conditioned ones. Scientific orthodoxy  holds that what cannot be readily measured or tested cannot exist, or is unworthy of serious attention. But emotional explanations for animal behavior need not be impossibly complex or unstable. They are just more difficult for the scientific method to check on in the usual ways, so cleverer and more skillful approaches are called for. Most branches of science are more willing to make successive evaluation of what may prove ultimately unknowable, rather than ignoring it altogether. 
 Question: The example of the baby seagull pecking the parent's bill is used to support that   _  . 
 Options: (A) it is an inborn ability for adults to look after the young (B) behaviors can be learned and involve no emotions (C) emotions are of great importance for survival (D) it takes time for animals to be conditioned 
 Asnwer: A
