Input: Consider Input: Passage: The city shares a 15-mile (24 km) border with Mexico that includes two border crossings. San Diego hosts the busiest international border crossing in the world, in the San Ysidro neighborhood at the San Ysidro Port of Entry. A second, primarily commercial border crossing operates in the Otay Mesa area; it is the largest commercial crossing on the California-Baja California border and handles the third-highest volume of trucks and dollar value of trade among all United States-Mexico land crossings. Question: Where is the next nearest commercial crossing at the border?

Output: Otay Mesa


Input: Consider Input: Passage: Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc², derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincaré (1900), Friedrich Hasenöhrl (1904) and others (see Mass-energy equivalence#History for further information). Question: In what year did Einstein create E = mc2?

Output: 1905


Input: Consider Input: Passage: The Japanese enlarged administration and appointed local leaders, which weakened the authority of local traditional leaders. Japan also tried to change the social organization in the islands from Matrilineality to the Japanese Patriarchal system, but with no success. Moreover, during the 1930s, one third of all land up to the high water level was declared the property of the Japanese government. On the archipelago, before it banned foreign traders, the activities of Catholic and Protestant missionaries were allowed. Indigenous people were educated in Japanese schools, and studied Japanese language and Japanese culture. This policy was the government strategy not only in the Marshall Islands, but on all the other mandated territories in Micronesia. On March 27, 1933, Japan handed in its notice at the League of Nations, but continued to manage the islands, and in the late 1930s began building air bases on several atolls. The Marshall Islands were in an important geographical position, being the easternmost point in Japan's defensive ring at the beginning of World War II. Question: What system of social organization was used in Japan?


Output: the Japanese Patriarchal system
