I'm taking a test and have to guess the right answer to the question after the article. Article: The American local food movement has been all about buying seasonal food from nearby farmers. Now, thanks to the Web, it is expanding to include far-away farmers too. A new start-up, Foodzie, is an online farmers market where small food producers and growers can sell their products. Foodzie was started by Mr LaFave and two of his friends, who met during college at Virginia Tech, where they would pay frequent visits to farmers markets. Last year, while living in North Carolina, one of them, Emily Olson, now 24, came up with one idea. She was working as a brand manager for a _ grocery chain and realized that people who enjoyed fine food but didn't work in the business had no way to discover handmade foods outside their local farmers markets. Small farmers had no way of finding or selling to faraway customers, either. Mr LaFAve and the third co-founder, Nik Bauman, both 25, worked in corporate sales and software development. "With business, food and computer science backgrounds, we figured we had everything we needed." Mr LaFAve said. The three quit their jobs, and opened this site to the public in December and the site has had 43,000 visitors in the past month. So far, 29 sellers have opened shops and 41 are in the process of opening them. The founders recently hired a fourth employee to help Ms Olson recruit new food producers at farmers markets and food shows. Mr LaFAve is convinced that the recession will not reduce people's interest in buying locally grown and handmade food. "There is misunderstanding that all these foods are more expensive than mass-produced alternatives," he said. "People are pouring their heart and soul into these products, and they are of the highest quality." Question: About the three founders, we know that _ . Options: A: they are of the same age B: they gave up their work to start the website C: they used to be colleague D: they majored in farming at college

I'm taking a test and have to guess the right answer to the question after the article. Article: Of all the websites,one that has attracted attention recently is _ .Most of this attention has come from the media and tells every reason why the website should be shut down.The threat of internet predators is indeed a tough reality,but shutting down the site is not the answer.If _ were shut down,another site would quickly take its place.Therefore,the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them. The key to staying safe on the Internet is to make sure that your profile is secure.The simplest way is to change the privacy setting on your profile to "private", which protects your information so that only the people on your friend list can view it.Although this is effective,it is not perfect.Predators can find ways to view your profile if they really want to,whether through hacking in or figuring out their way onto your friend list.Thus,you should never post too much personal information.Some people actually post their home and school addresses,date of birth,and other personal information, often letting predators know exactly where they will be and when.The most information that is safe is your first name and province.Anything more is basically inviting a predator into your life. Another big issue is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission. Most importantly, never,under any circumstances,agree to a real-life meeting with anyone you meet online.No matter how well you think you know this person, there are no guarantees that they have told the truth.But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are.Hopefully,the next time you edit your profile,you'll be more informed about the dangers of internet predators and take the steps to defend yourself. Question: The safest basic personal information that you can share online is . Options: A: your home address and birthday B: school address and your first name C: your first name and province D: your province and cell phone number

I'm taking a test and have to guess the right answer to the question after the article. Article: It's not just great minds that think alike. Dozens of the genes involved in the vocal learning that _ human speech are also active in some songbirds . And knowing this suggests that birds could become a standard model for investigating the genetics of speech production and speech disorders. Complex language is a uniquely human trait, but vocal learning -- the ability to pick up new sounds by imitating others -- is not. Some mammals, including whales, dolphins and elephants, share our ability to learn new vocalizations . So do three groups of birds: the songbirds, parrots and hummingbirds. The similarities between vocal learning in humans and birds are not just superficial. We know, for instance, that songbirds have specialised vocal learning brain circuits that are similar to those that mediate human speech. What's more, a decade ago we learned that FOXP2, a gene known to be involved in human language, is also active in "area X" of the songbird brain -- one of the brain regions involved in those specialised vocal learning circuits. Andreas Pfenning at the Massachusetts Institute of Technology and his colleagues have now built on these discoveries. They compared maps of genetic activity in brain tissue taken from the zebra finch, budgerigar and Anna's hummingbird, representing the three groups of vocal-learning birds. They then compared these genetic maps with others taken from birds and primates that can't learn new vocalisations, and with maps taken from the brains of six people who donated tissue to the Allen Brain Institute in Seattle. Their results showed that FOXP2 is just one of 55 genes that show a similar pattern of activity in the brains of humans and the vocal-learning birds. Those same genes show different patterns of activity in the brains of animals incapable of vocal learning. "The similarities are beyond one or a handful of genes," says Pfenning. "There are just systematic molecular similarities between song-learning birds and humans." "There's potential for songbirds to be used to study... Question: What can we infer from the passage? Options: A: FOXP2 was involved in human language about 12 years ago. B: Six people donated brain tissue to the Allen Brain Institute in Seattle. C: Experiments with songbirds are likely to help cure Huntington's disease. D: Constance Scharff discovered at the Free University of Berlin.
