(CNN) -- German art collector Cornelius Gurlitt, whose nearly priceless collection was confiscated because it was suspected to contain pieces looted by the Nazis, died Tuesday and left the masterpieces to a Swiss museum. One day after Gurlitt's death at the age of 81, the Museum of Fine Arts Bern announced that Gurlitt had named it "his unrestricted and unfettered sole heir." The news came as a surprise, the museum said Wednesday, because Gurlitt had never had any connection to it. The museum's directors are delighted at the news, they said in a statement, but also recognize that there are outstanding legal and ethical questions surrounding the collection. Gurlitt had undergone major heart surgery and was hospitalized for many weeks, his representative said in a statement. Gurlitt grabbed the attention of the art world when German prosecutors seized more than 1,200 paintings from his Munich apartment in 2012, including works by Picasso and Matisse. The collection was confiscated as part of an investigation into tax fraud, but then it was thought that some of the paintings may have been works that were looted by the Nazis. Just last month, part of the collection was returned to Gurlitt as part of a deal with Germany's cultural authorities and the Bavarian Justice Ministry. Under the agreement, works owned by Gurlitt that were not under suspicion were returned to him. Those suspected of being stolen were to be held securely while a task force investigates their provenance -- and will be returned to their original Jewish owners or their descendants if a claim is proven. Gurlitt's representative said that with the art collector's death, the investigation into the collection ceases. The court that was handling the investigation proceedings will now function as an estate court in the case. <sep>Who was the German art collector that had undergone major heart surgery?<sep>Cornelius Gurlitt
Yes

Grande dame of cooking still going strong at 90: Julia Child celebrates in San Francisco. How does it feel to turn 90 and have attained the status of an icon, a living legend? "It feels just like it felt before," Julia Child says with the throaty laugh familiar to millions who cut their culinary teeth on her "French Chef" television series. The show, along with her seminal book, "Mastering the Art of French Cooking" (1961), revolutionized the way America cooks and eats. While making light of the difference a day -- or another decade -- makes, Child intends to enjoy her birthday thoroughly. First, there will be all the public observances, including a sold-out dinner Thursday at San Francisco's tony Fifth Floor restaurant, which -- like dinners that night at 19 other venues across the country -- will benefit the scholarship fund of the International Association of Culinary Professionals (which Child co-founded). Friday to Sunday, the action moves to Napa, with both members-only and public events at COPIA: The American Center for Wine, Food and the Arts, of which she is an honorary board member. Aug. 15, her actual birthday, will see her in Maine at an annual gathering of nieces, nephews, their offspring and friends, who for many years have rolled a joined birthday celebration for several members of the group into a jolly reunion. The schedule Child and her assistant of 14 years, former pastry chef Stephanie Hersh, have laid out is not exactly a senior-citizen routine, even though Child has always been candid about her age and realistic in assessing her own capabilities. When the Pasadena native moved back to California from her long-time home in the Boston area last year, she also made the move from a condominium she and her late husband, Paul, had purchased many years ago to a progressive retirement home. She is in the most active of the four levels available, but should the need arise, she can move on to assisted living facilities within the same complex. <sep>Which show revolutionized the way America cooks and eats.<sep>"Mastering the Art of French Cooking"
No

When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison. <sep>What lived on prairies?<sep>Flowers, prarie dogs, bison

Yes
