Ques: Read the following article and select the best answer. Article: When several people look at the same person, it is not unusual for each of them to see different things; when you are alone observing one behavior or a person at two different times, you may see different things. The followings are but some of the factors that lead to these varying perceptions(,): (1) Each person's perceptions of others are formed by his or her own cultural conditioning, education, and personal experiences. (2) Sometimes perceptions differ because of what we choose to observe and how we deal with what've observed. It is not necessarily true that person perception is based on observations of a particular person. Your observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same standard to measure their parents, their friends, and strangers. (3) Sometimes we see only what we want to see or don't see what may be obvious to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory information is particularly obvious, but it can be done. We can ignore the _ ----"He's basically a good boy so what I saw was not shoplifting ." We can reduce the importance of the contradictory information ----"All kids get into mischief . Taking a book from a bookstore isn't such a big deal." We can change the meaning of the contradictory information--- "It wasn't shoplifting because he was going to pay for it later."... Question: The worst thing in selective perception is that _ . - the information received runs against your desire - facts can be twisted or totally ignored - importance of the contradictory information can be overrated - misbehaved children may not be punished
Ans: facts can be twisted or totally ignored

Ques: Read the following article and select the best answer. Article: Before leaving work, Steve Lee likes to use his cell phone to turn on his heat and air condition system at home. So by the time he gets through traffic into his front door, the temperature inside is perfect. You may wonder what a so-called smart home can do inside. Lee works for a company called Smarthome. com, testing and living with many of his company's home automation gadgets , like this multifunction touch screen that controls devices around the house and even connects to the Internet traffic cameras. "I have cameras, and they follow all the way down the freeway to work, "said Lee with pride, "What's going on at home when you are away? No problem, install some wireless cameras and controllers and from any computer in the world with an Internet connection, you can watch your house. " "You can check on the house, and I can look at the temperature. Believe it or not, if I want to turn on lights ahead of time, I can, "added Lee. We sat in Steve's California kitchen and with the right password, turned on the kitchen counter lights at his boss' house in Wisconsin. Steve did have permission to log on . "If you do know the password and you want to play a trick on your wife, you could turn lights on and off remotely. " This new technology, which can automatically turn on water sprinklers when humidity is low, or turn off a pool pump when it is not in use, is no longer expensive. Several hundred dollars for a basic system is enough and it is not hard to install. Sure the convenience is nice but many people who like the security advantages like making sure kids are safe with the help of camera monitors and bedside alerts. "I can notice that maybe one of my children wakes up in the middle of the night once the light switch is turned on. " What a smart home can't do is get you a snack and you have to leave the couch for that. Question: What can be inferred from this passage? - Steve's boss trusted him very much. - Steve doesn't like to play jokes on his family. - Steve could log on his boss' home because he had been given the key. - It's expensive and difficult to apply a basic smart home system.
Ans: Steve's boss trusted him very much.

Ques: Read the following article and select the best answer. Article: Doctors fighting malaria---one of the deadliest diseases on the planet--- may soon have a new affordable weapon in their smart phones. Researchers have found a way to use the phone's camera to detect the microorganism in the patient's blood that causes the disease. According to the World Health Organization, almost 600,000 people died of malaria in 2013, making this mosquito-borne disease one of the deadliest in the world. The saddest aspect of this calamity is that it affects mostly young children. Early detection of the infection is important for successful treatment. But since the first symptoms resemble ordinary flu, a microbiologist must look at a drop of a patient's blood under a microscope for a proper diagnosis. Scientists in Britain have now developed a smart phone attachment called Xrapid, that turns the phone into a 200-power microscope, while the attached app---based on facial recognition software - quickly detects the parasitic protozoa in the blood smear . Jean Viry-Babel is the CEO of IanXen, the company that developed the app. He says it is cheap and works on the spot. "So we take a high-definition picture of a sample of blood. We separate the red blood cells from the rest---the white blood cells, the platelets ---and we start looking at each of the red blood cells individually," said Viry-Babel. Viry-Babel says the app is affordable, easy to use and provides reliability of up to 98 percent. The only additional equipment required is an ordinary glass lab slide - called a "slate." "There's only one button, which is called "Diagnose". So you put it on the slate and you put it on the dried blood, and you press diagnose and it tells you yes or no," he said. Researchers say the field-testing of the device will begin in January and February in Tanzania, Benin and Indonesia --- while commercial use is scheduled to start by the end of March. They also plan to expand the versatility of the new device---teaching it to recognize other diseases, such as tuberculosis and Lyme Disease. Question: The text is meant to _ . - find a new way to treat malaria. - recommend a new smart phone. - promote a new program. - introduce a new device to detect disease.
Ans:
introduce a new device to detect disease.
