Input: Consider Input: Article: The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, Beautiful Inside My Head Forever, at Sotheby's in London on September 15th 2008. All but two pieces sold, fetching more than PS70m, a record for a sale by a single artist. It was a last victory. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brothers, filed for bankruptcy, starting the most severe financial crisis since the 1920s. The world art market had already been losing momentum for a while after rising confusingly since 2003. At its peak in 2007 it was worth some $65 billion, thinks Clare McAndrew, founder of Arts Economics, a research firm -- double the figure five years earlier. Since then it may have come down to $50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos , greed, passion and controversy in a way matched by few other industries. In the weeks and months that followed Mr. Hirst's sale, spending of any sort became deeply unfashionable. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector, they were down by nearly 90% in the year to November 2008. Within weeks the world's two biggest auction houses, Sotheby's and Christie's, had to pay out nearly $200m in guarantees to clients who had placed works for sale with them. The current downturn in the art market is the worst since the Japanese stopped buying Impressionists at the end of 1989. This time experts suppose that prices are about 40% down on their peak on average, though some have been far more volatile . But Edward Dolman, Christie's chief executive, says, "I'm pretty confident we're at the bottom." What makes this fall different from the last, he says, is that there are still buyers in the market, while in the early 1990s, when interest rates were high, there was no demand even though many collectors wanted to sell. Christie's earnings in the first half of 2009 were still higher than in the first half of 2006. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds -- death, debt and divorce -- still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return.
Answer: Some art dealers were awaiting better chances to come.

Output: Which of the following statements is true?

Input: Consider Input: Article: One summer my friend and I decided to go to Italy for a holiday and we decided to travel there without going through a travel agency. You know, you would be submerged in crowds of tourists and lose lots of opportunities to get familiar with the country more closely. We started to think over our trip and managed to come up with a free tour of Italy. The trip was not very long but it was still very impressive. We look forward to going there again! Of course, we spent lots of time arranging the trip, but it was well worth it! Of course I was afraid that something would go wrong and I was especially anxious about my visa, but everything went quite smoothly in the end. ks5u The most difficult part was getting a visa without an invitation. In the Italian consulate , one must hand in some official paper proving that one has a hotel booked for oneself in order to get the visa. Then we had to solve the ticket problem. Airlines often sell cheap tickets and we bought ours far in advance. The next step was to book a hotel. We finally booked a hotel about thirty km away from the heart of Rome and it was the perfect choice for our trip. Every day we took a train that carried us to the heart of Rome. Our big house, which was surrounded by the forest, was a rare girl for the fresh air and silence, beautiful views, hospitable hosts, comfortable living conditions delighted us to no end. Besides this, we were very lucky that our mistress was Russian. She gave us a lot of advice that was of great use. She told us what transport to choose and where the best places to go. Don't be afraid to arrange your trip by yourself. It's not difficult! The only thing I'll say right now is that we really enjoyed traveling by ourselves. We walked with a map and a guide-book to wherever we wanted and we even met some of our fellow countrymen on the way just two or three times. So, if you're also planning a "single" trip, don't forget to take a Russian-Italian phrasebook as people in Italy prefer to speak in their native tongue.
Answer: He had a great time there.

Output: Why does the author want to go to Italy again?

Input: Consider Input: Article: In the frozen continent of Antarctica scientists fear an alien invasion -- not from outer space, but carried in people's pockets and bags. Seeds and plants accidentally brought to Antarctica by tourists and scientists may introduce alien plant species which could threaten the survival of native plants in the finely balanced ecosystem. "The people that were carrying the most had lots and lots of seeds. They really were real threats," said Dana Bergstrom, from the Australian Antarctic Division. "When we take things in through hitchhiking then we get species which are competitive. The plants and animals there are not necessarily competitive, so we'd start losing various precious biodiversity on the (Antarctic) continent", Bergstrom told Reuters. Amongst the alien species discovered were the Iceland Poppy, and Annual Winter Grass -- all from cold climates and capable of growing in Antarctica. The Antarctic Peninsula, where most tourists travel, is now considered a "hot spot" on the frozen continent and the warmer the climate, the easier for seeds to grow. "The peninsula is warming at some of the greatest rates on the planet," said Bergstrom. The study, the first continent-wide assessment of invasive species in Antarctica, surveyed about 1,000 passengers during 2007-2008, the first year of the International Polar Year, an international effort to research the polar areas. Bergstrom said the one alien seed that had gained a foothold is Annual Winter Grass. It is a strong weed in the sub-Antarctic and is on the Antarctic island of King George. It has also made its way to the tail part of the Antarctic continent.
Answer: The human influence on the native plants.
