Problem: Given the question: Write a multi-choice question for the following article: Article: Plants may not have eyes and ears,but they can recognize their siblings ,and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete . Canadian researchers published that sea rocket,a common seashore plant,can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil,they "play nice" and don't send out more roots to compete.However,the moment one of the plants is thrown in with strangers,it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil. After reading Dudley's study,Bais decided to find the method behind the sibling recognition.Working in his laboratory,Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments,young seedlings were exposed to liquid media containing the root secretions from siblings,from strangers,or only their own secretions.The length of the longest lateral root was measured.The exposure of plants to the root secretions of strangers induced greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter,because so much of their energy is directed at root growth.Because siblings aren't competing against each other,their roots are often much shallower . Biedrzycki did the _ laboratory research,observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns."Arabidopsis roots are nearly translucent when they are young and were also twisted when I removed them from plates,"Biedrzycki notes."This manuscript is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions." The research also may have implications for the home gardener."Often we'll put plants in the ground next to each other and when they don't do well,we blame the...

input question: Write a multi-choice question for the following article: Article: The past week was possibly the most eventful in the history of customer technology markets,or to be precise, the 7-inch (17.8-cm) tablet market. Never before have three of thebiggest players in the industry scheduled what could be truly historic productlaunches so close together. Despite its name, the 7.9-inch iPad Mini is one of the largest among the mini-tablets. It's gotall the aesthetics of its earlier 9.7-inch iPad and is unbelievably thin-just 7.2 mm, 23 percentthinner than the iPad. Apple's iPad Mini Release date: Nov 2,2012 (Wi-Fi version) Operating system: iOS 6 Size: 19.9 x 13.5 x 0.7 cm Prices: $329 (16GB Wi-Fi), $429 (32GB Wi-Fi), $519 (64GB Wi-Fi), or $459 (16GB Data) $559 (32GB Data), $659 (64GB Data) Google may have been forced to cancel its Android event in New York City on Oct 29 due to the threat of hurricane Sandy, but that isn't stopping it from making same big announcements. For starters, Google has confirmed that the Nexus 10 will be running Android 4.2 out of the box, so get excited. It will also come equipped with a 10-inch display running at an impressive 2560x1600 resolution. On the inside, it'll have a A15 dual-core processor running alongside 2GB of RAM ,so expect the Nexus 10 to be a speedy little tablet. Google's Nexus 10 Release date: Nov 13,2012 Operating system: Android 4.2 Jelly Bean Size: 26.4 x 17.8x0.9 cm Prices: $399 (16GB), $449 (32GB) Microsoft's Surface is a bold product with some great touches. It doesn't feature a camera and focuses on Office software, which suggests Microsoft is focusing this product on an executive toy. There's no 3G connection (only Wi-Fi) so owners won't have to worry about an extra contract. The real delight, however, is Metro, the impressive navigation interface .It is beautifully designed with brightly colored squares for navigation. Pre-orders for Surface in the US sold out over the weekend, so it would seem customers are excited.

Please answer this: Write a multi-choice question for the following article: Article: From the outer of New York to the heart of Singapore, nature is everywhere you're not looking in some of Earth's most crowded big cities. Outdoor adventure is often just a few stops on the train - or a short drive- away from the annoying crowds. Here are a few favorites to get you going: Mount Hollywood Trail, Los Angeles It's not a skyscraper or a Ferris wheel, and there's no expensive restaurant up top. But if you want an absolutely unforgettable, no-admission-charged, 360-degree view of the entire Los Angeles region , it's yours. All you have to do is walk a little. One of the preferred exercise routes, the Mount Hollywood Trail, is easily accessed from the parking lot of the famous Griffith Observatory; you see what you get at the end of this steep 1.5-mile trail, which winds its way through the Griffith Park wilds up to the mountain's 1,640-foot peak. Bronx River, New York It may not be on your Top 10 list of things to do when you finally get to the Big Apple, but exploring the almost-secret river that flows through one of New York's most mysterious boroughs is an unforgettable experience. The Bronx River Alliance, a non-profit group that has worked tirelessly to bring the much-abused river back to life , operates cycling and canoeing trips along the river, from the rugged Hunts Point section down near the harbor on up through the borough. Southern Islands, Singapore Believe it or not, tightly packed Singapore does have plenty of open space left . There are actual trails right in the middle of everything, if you know where to look . But to really get away from it all, the Southern Islands, a small group of little green dots just off the city-state's southern shoreline, are just the thing. Lee Valley, London This East London river valley changed last summer, when anyone near a television got an eyeful of Olympic Park, built directly in the middle of the valley. Inside the park, beautifully landscaped sections quickly became a favorite relaxation spot for games goers. At present, you'll find miles of...
