I'm taking a test and have to guess the right answer to the question after the article. Article: Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2,160 miles (3,389 km), or a little more than a quarter of the diameter of the earth. Once a month, or more exactly, once every 29.5 days, at the time we call "full moon," its whole _ looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky. Yet the dark part of the moon's surface is not ly black; generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun's light onto our faces. In the same way the surface of the whole earth throws back enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark. Question: Which of the following is true according to the text ? Options: A: The moon which appears round at its brightest is called full moon. B: The moon's diameter is exactly one fourth of that of the earth. C: The light by which we see the old moon comes from the sun. D: The part of the moon which is not lighted by the sun is completely dark.

I'm taking a test and have to guess the right answer to the question after the article. Article: The story began with a young mother who had three sons. Unfortunately, the youngest son developed slow thinking skills, not having the intelligence of his brothers. With double duty as the mother of the household, she was exhausted, so that the youngest was often the target of anger and annoyance. Bad words, such as "you little fool" and the like, served as a daily meal for the youngest. The words and curses he got from the mother and ridicule from friends convinced him that he was distressing and embarrassing his family. Every morning he woke up with his own face staring from the mirror reflection, he started to say quietly and sadly, "The fool is going to school." As adult citizens, there was compulsory military service which should be lived. Thus, the youngest son also signed up and started to follow the various tests: a medical, physical ability test and other tests. On the day of the announcement, he was called into the board of examiners. In his mind, he convinced himself that he was the fool and couldn't pass the tests this time as he entered the room with his head down. It was not expected at all. The tests turned out to have the highest praise from the board of examiners. "Congratulations, young man! Your test results are incredible! You are really a great and talented young man. "Words from the board of examiners became the discovery of a new side of himself that was not known in advance. Voice kept echoing in his mind, such as "I, the great man, am in the shower", "The great man washes his face", "The talented young man again brushes his teeth" and so on. Confidence and improved self-image came beyond usual. 20 years later, the youngest established himself as a successful businessman who was admired and respected, and received many awards. The mindset and belief are the power behind the success that is within us. Whatever we think and believe in or minds continuously, it will eventually materialize in reality. That's the universally applicable law. Question: What happened to the youngest son later on? Options: A: He received aid from others. B: He became an admirable psychologist. C: He became confident and successful. D: He developed strange mental diseases.

I'm taking a test and have to guess the right answer to the question after the article. Article: Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it's used properly, you'll never have to worry about whether you will have to "friend" your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post. The problem with carrying out these privacy options is that they're just too confusing for most non-tech clever people to handle. And often, most people don't want to bother to take the time to learn. To simplify the process, we're offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private. Just make "Friend Lists". Yes, it will take some time, especially if you're connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook. Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won't have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named "Work", personal friends you're not very close with into a list called "Acquaintances", and people you're related to into a list called "Family". Those three main categories will separate out the groups of "friends" who you may want to hide some information from. To create a friend list, click on "Friends" at the top of the Facebook homepage. In the left-hand column, click "Friends" again under the "Lists" section. Now you'll see a button at the top that says "Create New List". Click it. In the pop-up that appears, you can name your list and pick members. If you've ever shared an application with your friends, the process of doing this will be very familiar. When you've finished making lists, you'll be able to use... Question: What function isn't understood by most people on Facebook? Options: A: Surfing the Internet. B: Setting safety protection. C: Sharing personal information. D: Making foreign friends.
