Extract the answer to the question from the following context. Question: Two advantages of the underground tunnel and bunker system were that the bunkers could be reoccupied after being knocked out and what else? Context: From early 1944 until the days leading up to the invasion, Kuribayashi transformed the island into a massive network of bunkers, hidden guns, and 11 mi (18 km) of underground tunnels. The heavy American naval and air bombardment did little but drive the Japanese further underground, making their positions impervious to enemy fire. Their pillboxes and bunkers were all connected so that if one was knocked out, it could be reoccupied again. The network of bunkers and pillboxes greatly favored the defender.

Extract the answer to the question from the following context. Question: Who is the son of the 41st president of the US? Context: New York is the most important source of political fundraising in the United States, as four of the top five ZIP codes in the nation for political contributions are in Manhattan. The top ZIP code, 10021 on the Upper East Side, generated the most money for the 2004 presidential campaigns of George W. Bush and John Kerry. The city has a strong imbalance of payments with the national and state governments. It receives 83 cents in services for every $1 it sends to the federal government in taxes (or annually sends $11.4 billion more than it receives back). The city also sends an additional $11 billion more each year to the state of New York than it receives back.

Extract the answer to the question from the following context. Question: What happened in Paris? Context: Parisians tend to share the same movie-going trends as many of the world's global cities, with cinemas primarily dominated by Hollywood-generated film entertainment. French cinema comes a close second, with major directors (realisateurs) such as Claude Lelouch, Jean-Luc Godard, and Luc Besson, and the more slapstick/popular genre with director Claude Zidi as an example. European and Asian films are also widely shown and appreciated. On 2 February 2000, Philippe Binant realised the first digital cinema projection in Europe, with the DLP CINEMA technology developed by Texas Instruments, in Paris.
