Please answer this: Extract the answer to the question from the following context. Question: What was sparked from these changes? Context: Shorter, black-and-white daily strips began to appear early in the 20th century, and became established in newspapers after the success in 1907 of Bud Fisher's Mutt and Jeff. Humour strips predominated at first, and in the 1920s and 1930s strips with continuing stories in genres such as adventure and drama also became popular. Thin periodicals called comic books appeared in the 1930s, at first reprinting newspaper comic strips; by the end of the decade, original content began to dominate. The success in 1938 of Action Comics and its lead hero Superman marked the beginning of the Golden Age of Comic Books, in which the superhero genre was prominent.

Please answer this: Extract the answer to the question from the following context. Question: What property can change depending upon the age of a tree when cutting it for wood? Context: Different pieces of wood cut from a large tree may differ decidedly, particularly if the tree is big and mature. In some trees, the wood laid on late in the life of a tree is softer, lighter, weaker, and more even-textured than that produced earlier, but in other trees, the reverse applies. This may or may not correspond to heartwood and sapwood. In a large log the sapwood, because of the time in the life of the tree when it was grown, may be inferior in hardness, strength, and toughness to equally sound heartwood from the same log. In a smaller tree, the reverse may be true.

Please answer this: Extract the answer to the question from the following context. Question: Where can customers get decent priced food in a nice setting? Context: In addition to the classical restaurants, Paris has several other kinds of traditional eating places. The café arrived in Paris in the 17th century, when the beverage was first brought from Turkey, and by the 18th century Parisian cafés were centres of the city's political and cultural life. The Cafe Procope on the Left Bank dates from this period. In the 20th century, the cafés of the Left Bank, especially Café de la Rotonde and Le Dôme Café in Montparnasse and Café de Flore and Les Deux Magots on Boulevard Saint Germain, all still in business, were important meeting places for painters, writers and philosophers. A bistro is a type of eating place loosely defined as a neighbourhood restaurant with a modest decor and prices and a regular clientele and a congenial atmosphere. Its name is said to have come in 1814 from the Russian soldiers who occupied the city; "bistro" means "quickly" in Russian, and they wanted their meals served rapidly so they could get back their encampment. Real bistros are increasingly rare in Paris, due to rising costs, competition from cheaper ethnic restaurants, and different eating habits of Parisian diners. A brasserie originally was a tavern located next to a brewery, which served beer and food at any hour. Beginning with the Paris Exposition of 1867; it became a popular kind of restaurant which featured beer and other beverages served by young women in the national costume associated with the beverage, particular German costumes for beer. Now brasseries, like cafés, serve food and drinks throughout the day.
