Q: Read the following article and select the best answer. Article: The disadvantage you usually find about MP3 players like the iPod is that they are too big. But get ready for the MP3 player in your hand to get much smaller--the size of a Band-Aid . It's called the Skinny Player, and it's being designed by industrial designers Chih-Wei Wang and Shou-His Fu. Unlike the current types of iPod Shuffles and iPod Nanos, the Skinny Player does not need to be fixed onto your clothes or put into your pocket. It could stick to your skin like you would attach a Band-Aid. But unlike Band-Aids, this tiny MP3 player will not lose its stickiness as you pull it off for the hundredth time. The Skinny Player features flexible speakers allowing the user to enjoy music conveniently. When it gets dirty, the user can simply clean it using a damp cloth. No batteries either. The Skinny Player's designers say it will be powered by body heat, using a flexible battery charging device that is in contact with skin whenever the player is being used. The design only include an on/off button and flexible speakers, no word yet on arranging the volume. Besides, the memory capacity won't be the best, as it is designed to only store one album. The small size and the ability to stick it onto your skin like a Band-Aid should make the Skinny Player perfect for runners who now depend on their iPod to keep them energized on the running path. Question: The best title for this passage can be _ . - Ipod--out of date MP3 player - Ipod--out of date mobile phone - Skinny Player--new type of MP3 player - Skinny Player--new type of mobile phone
A: Skinny Player--new type of MP3 player

Q: Read the following article and select the best answer. Article: It has been known that the octopus has many special skills, such as using hard shells for mobile homes and protection, disabling their suckers, plotting escapes, and even predicting World Cup soccer game outcomes. Can't we say it is a mysterious creature? While all these talents are impressive, they pale compared to its ability to "disappear" from plain sight. Researchers have long known that this is possible because of the presence of the organs under their skin, which expand or contract to produce a series of color1s, patterns and even skin textures in just milliseconds. Scientists had always believed that such a reaction was directed by a signal from the octopus's large, human-like eyes or brain. But a recent report published in the Journal of Experimental Biology by researchers from the University of California at Santa Barbara, indicate that the animal does not have to wait for a signal from its eyes or brain. It can "see" the light with its skin! UCSB doctoral student Desmond and Professor Todd said they have seen reports about octopus skin changing color1s in response to light with no signal from the eye or brain. However, there had been no follow-up to find out why this was the case and the two decided to see what they could uncover. They began by taking skin samples from a couple of California octopuses and exposing them to color1s, ranging from violent to orange and found that their skin is equipped with the same light-sensitive protein as is found in the cells in the retina of the eyes. Thanks to these proteins, the octopus can "see" the light and react without having to wait for a signal from the eyes or brain, thus enabling it to begin the escape process. Another research by University of Maryland researchers discovered that cuttlefish and squid share the same talent. Thanks to these findings researchers now know that their skin color1 can be controlled by both. What is still not clear is how the two come together to manage the whole process. The doctoral student plans to get to the bottom of the mystery. Question: What does UCSB research find? - Skin sample can be taken from California octopuses. - Octopuses have protein similar to cuttlefishes's. - Octopuses can "see" things by using its skin. - The skin of octopuses expands to disable an attacker.
A: Octopuses can "see" things by using its skin.

Q: Read the following article and select the best answer. Article: If your child has mobile internet access, it will be more difficult to monitor and control his or her internet use. Kids are turning to the internet for everything from hanging out with friends to shopping, which makes it harder for parents to keep track of their online activities. Fortunately, there are many choices for controlling what your kids see on their computers, laptops, and mobile devices. Content blockers and filters are great tools to use for younger kids. They allow you more control over where they go and what they do online. A content blocker can block some unhealthy websites or limit a child's search to the kind of sites. A content filter can scan sites and pictures and block those sites that contain certain words, key phrases, or content. Consider tracking software for older teenagers. This software enables you to see which sites your children have visited, tracking their path online. This tool gives young people more freedom to explore the Internet, but it also allows you to check that they are using the internet responsibly. Let your teenagers know that you trust them, but that you will be regularly checking that they are visiting appropriate sites online. Even if you use content blockers, filters, and trackers, you know that a lot of kids figure out ways to get around these, so it's important to remain alert . Remember that not all adult sites can be identified by blocker, filter, or tracker software. That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up. Nothing can replace involvement and supervision by adults. Keep monitoring how your kids use the internet on a regular basis without getting into the role of internet traffic police. Question: Parents should remain alert when they monitor kids' internet use because _ - content blockers, filters, and trackers are useless. - lots of kids figure out ways to get around content blockers, filters, and trackers. - not all adult sites can be identified by blocker, filter, or tracker software - nothing can replace involvement and supervision by adults
A: lots of kids figure out ways to get around content blockers, filters, and trackers.

Q: Read the following article and select the best answer. Article: Chicken soup has long been a comfort food for people with cold symptoms. Whether the remedy comes from the warmth and comfort of the soup or from actual cold-fighting ingredients in the meal, it is still up for debate. Chicken Soup: Just the Evidence _ The heat, salt, and hydration provided by chicken soup may actually fight the cold virus. Laboratory studies have shown that ingredients of chicken soup with vegetables could kill viral cells and prevent the growth of new ones. The soup may also provide an anti-inflammatory effect that helps reduce cold symptoms. Unfortunately, the benefits of chicken soup appear to be limited by how quickly the soup leaves the body. There is no indication that chicken soup would help in the prevention of colds, but its use as a remedy for symptoms is common. It is largely a safe remedy with no ill side effects, and scientific evidence points more in favor of its cold-fighting properties than against it. The Downside of Chicken Soup Evidence in support of chicken soup's antiviral properties is not yet solid enough to prove true, reliable medicinal effects. Although the evidence based on personal experiences and existing research seem to support a good effect of chicken soup, a clinical trial would be very difficult to perform. In addition, some people with food allergies or sensitivities to salt may experience ill side effects from chicken soup. Unbroken bones may also lead to a chocking risk, particularly for children. However, the potential benefits of chicken soup seem to far outweigh the possible risks. Question: What's the author's opinion on chicken soup? - It is good for people with colds to have chicken soup. - Scientists have found solid evidence about the benefits of chicken soup. - Chicken soup can take the place of other medicines for colds. - People still argue whether chicken soup has effects on cold symptoms.
A: It is good for people with colds to have chicken soup.
