Read the following article and select the best answer. Article: A report on a new software that enables eyes to do the typing appears in Wednesday's edition of the journal Nature. Replacing a keyboard or mouse, eye-scanning-cameras mounted on computers have become necessary tools for people without limbs or those affected with paralysis. The camera tracks the movement of the eye, allowing users to "type" on a virtual keyboard as they look at the screen. And now, researchers from the Cavendish Laboratory at prefix = st1 /CambridgeUniversitysay they have developed software that replaces the standard QWERTY keyboard layout with one that is nearly twice as efficient, more accurate and easier on the eyes. Called Dasher, the prototype program looks into the natural gaze of the eye and makes predictable words and phrases simpler to write. Any off-the-shelf camera capable of scanning eye movement can be used with Dasher, though the person must sit fairly still during the interaction. The letters of the alphabet appear in a single column on the right of the screen, with an underline symbol to represent a space. Each letter is framed by a color1ed box. As the user looks at a particular letter on the right side of the screen and drags it to the left with their eye, another sub-alphabet column begins to emerge inside the box on the right-hand side, along with more letters framed in color1ed boxes. Dasher is designed to anticipate which letter will be needed, so although the successive sub-alphabet columns are initially very small, the letters or combination of letters that appear are most likely to be used next in that sequence. For example, if a person starts with the letter "h", the language models in Dasher will bring up "a" "e" "i" "o" and "u" in the sub-alphabet box, along with a few other possible combinations like "ello" to form the word "hello". Each box has a complete alphabet within it, though the first letters to appear have the highest probability of usage. The letters are then placed together to form a sentence on the left side of the screen. Researchers say people... Question: With the new software Dasher, people can type with their eyes through _ . - a computer screen with eye-scanning sensors - an eye-scanning camera on computer - a color1ed box attached to the computer - a regular keyboard with sensors
an eye-scanning camera on computer

(Question)
Read the following article and select the best answer. Article: As the semester ended, students had a chance to _ . They got to grade me anonymously , assessing the ability of my thinking, my organizational skills and the depth of my knowledge. Such evaluations keep me alert to what works and what doesn't. Students reflect my performance back to me, and I'm glad to learn what they think of my teaching so that I might try to improve. This system reflects many aspects of my work. There is, of course, nothing wrong with it. But this system assumes that what students need is the same as what they want. Reading my evaluations every semester has taught me otherwise. Actually many students' expectations for their courses have already changed, reflecting, in part, the business model many universities are following: classes are considered services, and parents are eager to get their money's worth from their children's education. Students feel pressure from their parents to get practical use from their courses. This could make sense for an engineering course, but in my field, creative writing, which rarely trains up excellent 21-year-old writers, it is more difficult to provide the results that the career-minded students desire. Then I tried some teaching techniques to change the criticism of those unhappy students to the opposite and improve my student evaluations. My record would accurately reflect a smart, attentive, encouraging teacher. However, I would admit that they loved me simply because I agreed writing should be easy. I know other teachers have done the same thing: teach your heart out to the teachable but be sure to please the unteachable; keep your ratings high, like a politician trying to improve his poll results. I believe in the struggle. But I still can't help wincing when I read, "The instructor is mean." "Marcus is not committed to my work." "This class sucks." The business model has taught me that customers are always right. And maybe a few more dissatisfied customers would mean a better learning experience. Question: What can we infer from the passage? - Parents don't care about their money spent on their children's education. - The writer adopted some teaching methods so that he improved his student evaluations. - Similar to other teachers, the writer struggled to work as politicians. - The students intended to punish their teachers by giving comments.
(Answer)
The writer adopted some teaching methods so that he improved his student evaluations.

Ques: Read the following article and select the best answer. Article: What do you hear? Sounds all around you! You can hear the sound of traffic, the wind in the trees, a dog barking, your own breathing and lots of other things. But what is sound? Sound happens when something vibrates or shakes. We can make something vibrate by hitting it. Try this experiment. Put your ruler on your desk so that part of it sticks out over the edge . Put your hand on the part of the ruler that is on the desk. Now pull the part that is sticking out over the edge down, and then let it go. The part you let go will vibrate. It will move up and down very quickly, and give out sound. The part of the ruler sticking out over the edge of the desk produced the sound. If you make that part longer, you will hear a lower sound. When you shorten it, you will hear a higher sound. Why does this happen? When you shorten the ruler, it will vibrate more quickly. When something vibrates more quickly it produces a higher sound. If you _ the ruler, it will vibrate more slowly. When something vibrates more slowly, it produces a lower sound. Question: We can hear a_sound if we make the part of the ruler sticking out over the edge of the desk longer. - higher - lower - strong - nice
Ans: lower
