Input: PHOTOGRAPH COLLECTING gains new stature as prices rise. Price records are being set at auctions this week. At Christie's, a folio of 21 prints from Alfred Stieglitz's "Equivalents" series sold for $396,000, a single-lot record. Other works also have been exceeding price estimates. In part, prices reflect development of a market structure based on such variables as the number of prints. This information used to be poorly documented and largely anecdotal, says Beth Gates-Warren of Sotheby's. "There is finally some sort of sense in the market," she says. Corporations and museums are among the serious buyers, giving greater market stability, says Robert Persky of the Photograph Collector. "When I see prints going into the hands of institutions, I know they aren't going to come back on the market." Most in demand: classic photographs by masters such as Stieglitz and Man Ray. But much contemporary work is also fetching "a great deal of money," says Miles Barth of the International Center of Photography.

Does the response "None" correctly answer the question "How many of Alfred Stieglitz's prints sold at a record price?"?

Input: Honours and legacy In 1929, Soviet writer Leonid Grossman published a novel The d'Archiac Papers, telling the story of Pushkin's death from the perspective of a French diplomat, being a participant and a witness of the fatal duel. The book describes him as a liberal and a victim of the Tsarist regime. In Poland the book was published under the title Death of the Poet. In 1937, the town of Tsarskoye Selo was renamed Pushkin in his honour. There are several museums in Russia dedicated to Pushkin, including two in Moscow, one in Saint Petersburg, and a large complex in Mikhaylovskoye. Pushkin's death was portrayed in the 2006 biographical film Pushkin: The Last Duel. The film was directed by Natalya Bondarchuk. Pushkin was portrayed onscreen by Sergei Bezrukov. The Pushkin Trust was established in 1987 by the Duchess of Abercorn to commemorate the creative legacy and spirit of her ancestor and to release the creativity and imagination of the children of Ireland by providing them with opportunities to communicate their thoughts, feelings and experiences. A minor planet, 2208 Pushkin, discovered in 1977 by Soviet astronomer Nikolai Stepanovich Chernykh, is named after him. A crater on Mercury is also named in his honour. MS Alexandr Pushkin, second ship of the Russian Ivan Franko class (also referred to as "poet" or "writer" class). Station of Tashkent metro was named in his honour. The Pushkin Hills and Pushkin Lake were named in his honour in Ben Nevis Township, Cochrane District, in Ontario, Canada. UN Russian Language Day, established by the United Nations in 2010 and celebrated each year on 6 June, was scheduled to coincide with Pushkin's birthday.

Does the response "Natalya Bondarchuk" correctly answer the question "The biographical film based on Pushkin's life was directed by who?"?

Input: Have you ever looked closely at a globe? That continents look like a giant jig-saw puzzle. North America looks like it could fit next to Europe. The edge of South America matches Africa. Scientists noticed these same features. It caused them to start asking questions. They wanted to know if these continents were was connected? If so, how can something so large move so far? What could possibly have enough force to move such a giant slab of rock? Is there other evidence that can provide clues to the past positions of continents? How can answering these questions help us? A scientist named Alfred Wegener had these same questions. Wegener look at rocks on both sides of the Atlantic Ocean. He noticed they were the same type and age. He thought that the rocks must have formed side by side. He proposed that the rocks then drifted apart. One part went with North America. The other part stayed with Europe.

Does the response "He thought that the rocks must have formed side by side. He proposed that the rocks then drifted apart" correctly answer the question "Why does Wegener propose the continents look like a giant jigsaw puzzle?"?

Input: Above were just a few things that caused habitat loss or change. There are many ways in which living organisms can affect their ecosystem. In some areas, it is because of fire management. Fire is a natural event, so managing fire correctly is very important. In other areas, fisherman have taken too many fish from one area. This places the species at risk of extinction. It also affects other living things that may rely on these fish for food. The image below shows a picture of a mine. Mining changes the Earths surface. This area may once have been a forest or a prairie. Think about how many plants and animals may once have lived here. Now it is a giant hole in the ground. Pollution is also a major factor in habitat loss and change.

Does the response "Forest get crowded with plants and animals" correctly answer the question "How does mining change the earth's surface?"?

- no
