Problem: A number of studies have reported associations between pathogen load in an area and human behavior. Higher pathogen load is associated with decreased size of ethnic and religious groups in an area. This may be due high pathogen load favoring avoidance of other groups, which may reduce pathogen transmission, or a high pathogen load preventing the creation of large settlements and armies that enforce a common culture. Higher pathogen load is also associated with more restricted sexual behavior, which may reduce pathogen transmission. It also associated with higher preferences for health and attractiveness in mates. Higher fertility rates and shorter or less parental care per child is another association that may be a compensation for the higher mortality rate. There is also an association with polygyny which may be due to higher pathogen load, making selecting males with a high genetic resistance increasingly important. Higher pathogen load is also associated with more collectivism and less individualism, which may limit contacts with outside groups and infections. There are alternative explanations for at least some of the associations although some of these explanations may in turn ultimately be due to pathogen load. Thus, polygny may also be due to a lower male:female ratio in these areas but this may ultimately be due to male infants having increased mortality from infectious diseases. Another example is that poor socioeconomic factors may ultimately in part be due to high pathogen load preventing economic development.
What does avoidance of other groups reduce?
The answer is the following: pathogen transmission

Problem: Schwarzenegger came out of retirement, however, to compete in the 1980 Mr. Olympia. Schwarzenegger was training for his role in Conan, and he got into such good shape because of the running, horseback riding and sword training, that he decided he wanted to win the Mr. Olympia contest one last time. He kept this plan a secret, in the event that a training accident would prevent his entry and cause him to lose face. Schwarzenegger had been hired to provide color commentary for network television, when he announced at the eleventh hour that while he was there: "Why not compete?" Schwarzenegger ended up winning the event with only seven weeks of preparation. After being declared Mr. Olympia for a seventh time, Schwarzenegger then officially retired from competition.
For what Hollywood role was Schwarzenegger training in 1980?
The answer is the following: Conan

Problem: Paris is a major international air transport hub with the 4th busiest airport system in the world. The city is served by three commercial international airports: Paris-Charles de Gaulle, Paris-Orly and Beauvais-Tillé. Together these three airports recorded traffic of 96.5 million passengers in 2014. There is also one general aviation airport, Paris-Le Bourget, historically the oldest Parisian airport and closest to the city centre, which is now used only for private business flights and air shows.
What is the oldest air port in Paris?
The answer is the following: Paris-Le Bourget

Problem: In 1964 Israel hosted and won the Asian Nations Cup; in 1970 the Israel national football team managed to qualify to the FIFA World Cup, which is still considered[by whom?] the biggest achievement of Israeli football.[citation needed] The 1974 Asian Games held in Tehran, were the last Asian Games in which Israel participated, and was plagued by the Arab countries which refused to compete with Israel, and Israel since ceased competing in Asian competitions. Israel was excluded from the 1978 Asian Games due to security and expense involved if they were to participate. In 1994, UEFA agreed to admit Israel and all Israeli sporting organizations now compete in Europe.[citation needed]
When did Israel host and win the Asian Nations Cup?
The answer is the following:
1964
