TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: Giant pandas are now extremely rare. Their number is less than 1,000 in the wild. The hunting of pandas has been banned for many years, so this is not the problem. Destruction of its habitat, when areas are cleared for growing crops, is one of the main reasons for panda's decline . Another reason is that the bamboo on which they mainly feed, is dying back. The pandas find it difficult to move to new feeding areas. As the bamboo disappears, the pandas simply starve to death. Bamboo is a poor source of food, and pandas have to eat up 45kg of it every day, a process that takes them up to 16 hours. The process goes on day and night, with the pandas in a constant cycle of eating for eight hours and sleeping for four. They can eat other foods, but will rather starve than change their diet when bamboo is scarce. Giant pandas are very good climbers, and use this skill to escape from the enemy. The giant panda lives alone for most of its life, only coming together with another of its species for long enough to mate. A newborn panda baby is born hairless and blind, is about 15cm long and weighs only 100g. The baby will stay with its mother for about 18 months, until it is able to set up its own territory Chinese and American scientists are studying giant pandas and their habits in order to put in place a major conservation programme. Zoos around the world are taking part in panda breeding programmes. There is still hope that with human's help, the giant panda can survive in the wild.
Answer: Nearly 2 tons

SOLUTION: How much bamboo does a panda eat every year?

PROBLEM: Article: Imagine a picnic dinner held at a location only made known hours before the meal, where guests are invited to decorate tables and chairs, bring their favorite dishes and wear white to reflect the simplicity of the event. This was the scene at a PopUp dinner held on June 13 in Brooklyn, New York's Prospect Park. PopUp dinners are popping up nationwide -- not just in Brooklyn. Garrett Sathre and his wife and business partner, Nicole Benjamin-Sathre are the team behind Hand Made Events and the creators and hosts of PopUp dinners. Sathre, a former restaurateur and head chef with Bubba's Diner and Kitchen 39, both located in the Bay Area, came up with the concept of the flash dinner after he was inspired by the annual Diner en Blanc held in Paris. In 2011, Hand Made Events used the power of social media to get the word out and soon, enough interest was attracted. In October 2011, it held its first flash dinner, calling the evening Le Diner a San Francisco at Golden Gate Park's outdoor Music Pavilion. He described it as a picnic dinner for 3,500 people."I thought we would have anywhere between 300-500 people to attend. Two articles ran a week later about my crazy idea and we got 15,000 emails within three days,"Sathre said. After the success of the San Francisco dinner, Sathre decided to expand his"crazy idea"and hold dinners across the country in major markets such as Brooklyn, Los Angeles and San Francisco. Sathre says their Brooklyn PopUp on June 13 sold 5,000 tickets in just four days with 5,000 on the waiting list raising over $160,000 in ticket sales. Those are some big numbers. Hand Made Events partners with the Prospect Park Alliance and gives all of their proceeds to the non-profit group. In total, the Brooklyn PopUp dinner raised over $60,000 for the Prospect Park Alliance. Hand Made Events sees the same interest in their smaller city locations."We have seen a 30 percent increase in our smaller markets -- Minneapolis, San Diego, Charleston, and Miami every year,"Sathre said. Hand Made Events has eight more dinners planned nationwide this year, and six already scheduled for next year. The popularity is not just here in the states. Sathre says he sees photos of other groups holding similar events everywhere through social media. Just last year, Hand Made Events helped a woman in Kenya plan her own flash dinner via Skype."This event crosses and appeals to all cultures. There are not many events, if any, that bring all people together like the PopUp,"he said.
Answer: Popular and simple.

SOLUTION: Which words can best describe the event held in Brooklyn?

PROBLEM: Article: SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution--a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. "We were praying to the parking god that we'd find a spot," she said. "If we had the app, we would not have to pray to the parking god." But the system could come with serious consequences. Some people say that drivers searching for parking could end up focusing on their phones, not the road. "It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone but which city officials say they hope to bring to all similar devices. When it is started up, the city's parking app warns drivers not to use the system while in motion. But safety advocates said that might not be sufficient. After all, they say, texting while driving is illegal in California and in many states, but a number of surveys, including one by the Pew Research Center, show that many Americans do it anyway. Elizabeth Stampe, executive director of Walk San Francisco, a pedestrian advocacy group, said she hoped the new parking app would lead to fewer accidents. "It's an innovative idea," she said. "The safe way for people to use the device is for them to pull over, which they know they should do. The question is whether they will." But Ms. Soltani, the TV reporter, said using the app would probably join the group of activities already performed by drivers. "We're already looking at Google Maps and Facebook on the phone while we drive," she said. "Aren't we always looking at something on our phone, or changing the radio, or drinking coffee? You're always slightly distracted when you're driving."
