Question: In the 1930s, the experimental station W3XE, owned by Philco, became the first television station in Philadelphia; it became NBC's first affiliate in 1939, and later became KYW-TV (CBS). WCAU-TV, WPVI-TV, WHYY-TV, WPHL-TV, and WTXF-TV had all been founded by the 1970s. In 1952, WFIL (now WPVI) premiered the television show Bandstand, which later became the nationally broadcast American Bandstand hosted by Dick Clark. Today, as in many large metropolitan areas, each of the commercial networks has an affiliate, and call letters have been replaced by corporate IDs: CBS3, 6ABC, NBC10, Fox29, Telefutura28, Telemundo62, Univision65, plus My PHL 17 and CW Philly 57. The region is served also by public broadcasting stations WYBE-TV (Philadelphia), WHYY-TV (Wilmington, Delaware and Philadelphia), WLVT-TV (Lehigh Valley), and NJTV (New Jersey). In September 2007, Philadelphia approved a Public-access television cable TV channel.

Answer: 1939
Question: human activities are more likely to affect the habitat in areas of permanent water (oases) or where water comes close to the surface. Here, the local pressure on natural resources can be intense. The remaining populations of large mammals have been greatly reduced by hunting for food and recreation. In recent years development projects have started in the deserts of Algeria and Tunisia using irrigated water pumped from underground aquifers. These schemes often lead to soil degradation and salinization.
Try to answer this question if possible: Why did development projects start in Algeria and Tunisia?
Answer: unanswerable
Question: The palace, like Windsor Castle, is owned by the Crown Estate. It is not the monarch's personal property, unlike Sandringham House and Balmoral Castle. Many of the contents from Buckingham Palace, Windsor Castle, Kensington Palace, and St James's Palace are part of the Royal Collection, held in trust by the Sovereign; they can, on occasion, be viewed by the public at the Queen's Gallery, near the Royal Mews. Unlike the palace and the castle, the purpose-built gallery is open continually and displays a changing selection of items from the collection. It occupies the site of the chapel destroyed by an air raid in World War II. The palace's state rooms have been open to the public during August and September and on selected dates throughout the year since 1993. The money raised in entry fees was originally put towards the rebuilding of Windsor Castle after the 1992 fire devastated many of its state rooms. 476,000 people visited the palace in the 201415 financial year.
Try to answer this question if possible: How many people visited the palace in the 2014.2015 fiscal year?
Answer: 476,000 people
Question: A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturated depending on the detailed structure of the fatty acids involved. Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans-isomer bonds; these are rare in nature and in foods from natural sources; they are typically created in an industrial process called (partial) hydrogenation. There are nine kilocalories in each gram of fat. Fatty acids such as conjugated linoleic acid, catalpic acid, eleostearic acid and punicic acid, in addition to providing energy, represent potent immune modulatory molecules.
Try to answer this question if possible: What needs to be examined to determine whether a fat can be classified as saturated or unsaturated?
Answer:
the detailed structure of the fatty acids involved
