I'm taking a test and have to guess the right answer to the question after the article. Article: Chokwe Selassie, aged 13, is working hard to help drivers avoid potholes . The eighth-grader was inspired to kick off his creation on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. He decided to do something about the pothole problem in his city. Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. When the app detects a pothole, it is highlighted in red. And if you get close to the pothole, your phone will warn you with a beep. Drivers can also use the app to report any potholes and look for other routes they can take to avoid roads that have them. The app relies on current available information about the streets of Jackson, already stored in a database of the city's 311 call system. Through the call system, citizens dial 3-1-1 to report non-emergency problems which include potholes. Chokwe and his friends determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test the prototype. While developing the app, the boys took part in a Minority Male Makers Program sponsored by Verizon and held at Jackson State University. They learned 3D printing and design, and how to create apps. Through the program Chokwe and his friends received encouragement and guidance. Although the app isn't yet available for sale, Chokwe is already looking for ways to improve the app. He hopes to add more to it until it spreads all over the country. Question: How does the app work through the 311 call system? Options: A: By replying to citizens' calls. B: By broadcasting traffic accidents. C: By settling non- emergency problems. D: By using its information about potholes.

I'm taking a test and have to guess the right answer to the question after the article. Article: Even if you are saying and doing the right things at your job and in your personal life, you could be making a bad impression on everyone with what you don't say. That's because much of our reactions to others are based on body language. If your body language is communicating a negative message, that's the message you could be sending, regardless of what actual words come out of your mouth. What are negative messages sent via body language? Things like having arms folded across your chest can show hostility . Lack of eye contact can indicate shiftiness . An unsmiling face could communicate a variety of things, like anger, disappointment, or sadness, depending upon what other facial expressions are included. Want to know what body language communicates? Watch a TV show or a movie with the sound off, and see how much you can figure out of the plot, or at least you can get a sense of what is going on. However, many of the clues that indicate negativity could also be the result of nervousness or other issues. For example, somebody who doesn't make eye contact could simply be nervous. The same goes with a not-so-warm hand-shake. Or, someone folding his arms could simply be more comfortable with the arms that way, not realizing what the arms' position sends. Someone who doesn't smile could be self-conscious about her teeth. At any rate, the person who sends off bad body language may not even realize that they're doing it. Unfortunately, some people who do recognize what body language communicates are scam artists. They may have the firmest handshake, the shiniest smile, and make the greatest eye contact to convince others of their sincerity, because they know how much this nonverbal communications plays a part in communicating sincerity. Yet people _ it, because their body language seems sincere. But what if you're in the opposite situation? If you're not sure what your body language is communicating, ask a trusted friend for help. You can also concentrate on standing up straight and sitting up straight, if... Question: A serious face could indicate a lot of different information _ . Options: A: especially anger and disappointment B: together with the arms folded across C: together with other facial expressions D: depending on others' facial expressions
