Input: Consider Input: Article: The City of Christchurch, New Zealand was struck by a 7.1magnitude earthquake on the early morning of Saturday, September 4, 2010. No tsunami alert was reported. The country's army troops were on standby to assist victims and disaster recovery operation. New Zealand's Prime Minister John Key, flew to the affected area to inspect and assess the situation of the damaged city. The Prime Minister said that the full assessment of the damages would possibly take months to know the severity of damages. Based from his assessment on what he saw in the area, it could cost at least 2 billion New Zealand dollars or US$1.4 billion for reconstruction. "An absolute miracle that no one died," Prime Minister John Key said. Two were seriously injured from this quake and thousands of local residents were awakened after being shaken at 4:35 a.m. of that Saturday. There were people trapped inside the damaged buildings but fortunately none were reported dead from the rubble of the damaged buildings. "We're all feeling scared--we've just had some significant aftershocks," a survivor told TV One News. "Tonight we're just people in the face of a massive natural disaster, trying to help each other and we're grateful we haven't lost a life." GNS Science reported 29 aftershocks within the 14 hours after the quake, with strength from magnitude 3.7 to 5.4. _ . The country experiences more than 14,000 earthquakes a year--but only about 150 are felt by people. "Many buildings here were built with earthquake protection measure. However, in most cities in developing countries, people build how they want to and there're no building controls to force them to build to a higher standard that's safe," Andrew Charleson, an architecture professor at Victoria University of Wellington told CNN.
Answer: 0.

Output: How many people were killed in the New Zealand earthquake on September 4, 2010?

Input: Consider Input: Article: If you've ever owned a chimney, you know that it can get pretty dirty. There's a whole lot of soot that gets stuck on the inside. That stuff has to get cleaned, or you could have a serious fire risk. While nowadays we have easier ways of doing this dirty job, in the way back days somebody used to climb up the chimney and clean all that soot. And the thing is, not just anybody could do it. You had to be really small to fit up in the chimney, so they used to give the task to kids - some as young as four or five years old. They worked for their boss known as a master-sweep. They were often covered in soot, and were very likely to get burned. They often developed what became known as soot wart, a form of cancer. Are your unfairness bells ringing? William Blake's certainly were. The physical dangers and widespread unfairness of the chimney-sweeping job really stuck in his throat, so much so that he wrote not one, but two poems called "The Chimney Sweeper". The first poem (the one we're discussing here)was published in 1789 in a book called Songs of Innocence. These little poems took children and the joys of childhood innocence as their subject. As you've probably guessed by now, many of the poems in Songs of Innocence, like "The Chimney Sweeper", are about the ways in which childhood innocence is destroyed by unkind old adults. For Blake, innocence is, in many ways, a total joke. It doesn't exist, because it's always taken away by the realistic world - chimney-sweeping, death, poverty, etc. What does a five-year-old chimney sweeper in 18th-century England have to do with you? More than you might think. It is reported that 150 million kids are in child labor in developing countries. Many of them work long hours and face dangerous health risks. Like Blake's chimney sweeper, these kids are not even given a chance at innocence because experience keeps getting in the way.
Answer: Dirty and dangerous.

Output: Which of the following can best describe the chimney-sweeping job?

Input: Consider Input: Article: Why does the Leaning Tower of Pisa in Italy lean? It leans because of a mistake. It has leaned almost since the day the tower was built. In 1173, the people of Pisa, Italy, wanted to build a bell tower. They wanted the tower to be the most beautiful bell tower in all of Italy. The city also needed a bell tower because the church did not have one. However, there was a problem. As soon as the first floor of the building was finished, the tower started to lean. Builders tried to make the building straight again as they added more floors, but they couldn't figure out how to make it stop leaning. It took almost 180 years to finish the tower. Since then, the tower has leaned by another millimeter every year. Today, the Leaning Tower has eight floors and is 54.5 meters tall. By 1990, it was leaning by about 4 meters to one side. It was also slowly sinking into the ground. Many people became worried that it would soon fall apart. In 1998, repair works began on the tower, and by the end of 2001, it had been moved back by 45 centimeters. The tower will still lean, however, so it will need to be repaired again---in another 200 years.
Answer: They wanted to build a leaning tower.
Output: why did the people of Pisa want to build the tower?
