Read the following article and select the best answer. Article: It takes less than six seconds to leave a first impression. It is said that we ought not judge a book by its cover, but come on, isn't it the color, the design, the layout, and the title that draw us to pick up a book we've never heard of before? Notice what your assumptions are about a person when you are first introduced to her or him. Something that most of us don't take notice of is how we stand or walk. Let's say you are going for a job interview. Within seconds you have already said a lot about yourself by the way you walk. The majority of us walk around everyday without paying any attention to what we are saying even though we are not uttering a word. There is a lot that can be said about body language from the clothes you wear to the gestures you make. I took notice of this topic recently as I recalled something about changing my posture to improve my level of confidence. I was about to venture on a new project, which would take me out of my comfort zone. My gremlins were having a field day with me uttering all kinds of reasons why I couldn't do a good job with this new opportunity. I tucked in my tummy , put my shoulders back , held my head high , and took a walk. Soon thereafter, I felt so much better. I approached the project with new possibility. Wow, what a difference ! Try it ! The ability to capture your audience when you walk into a room is sure to start you off on the right foot when going on an interview. Non-verbal signals have five times the impact of verbal signals. So you can count on losing your audience when you walk in with head down dragging your feet regardless how much you try to change it. Question: The author probably believes that _ . - non-verbal signals are more important than verbal signals - non-verbal signals are not so easy to catch - we mainly rely on verbal signals during an interview - we shouldn't pay too much attention to our non-verbal signals
(Answer)
non-verbal signals are more important than verbal signals

Question: Read the following article and select the best answer. Article: What will power your house in the future? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be artificial leaves. Natural leaves can change sunlight and water into energy. It is known as photosynthesis . Now researchers have found a way to imitate this process. The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts . Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell, using those two materials to produce electricity, located either on top of a house or beside the house. Though the leaf is shaped like a poker card, scientists stated that it is promising to be an inexpensive somtoe of electricity in developing countries. "One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology," said an American scientist, Docera. An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but too expensive and unstable for practical use. The new leaf, however, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf could operate continuously for at least 45 hours. The wonderful improvements come from Nocera's recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more effective at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available. Hopefully, each home could possible have the access to the new application in the future. Question: The purpose of this article is to _ . - promote the new product - ask people to do the research - introduce a new kind of energy - show the process of photosynthesis
Answer:
introduce a new kind of energy
