The problem: Answer a question about this article:
The World Intellectual Property Organization (WIPO) recognizes that conflicts may exist between the respect for and implementation of current intellectual property systems and other human rights. In 2001 the UN Committee on Economic, Social and Cultural Rights issued a document called "Human rights and intellectual property" that argued that intellectual property tends to be governed by economic goals when it should be viewed primarily as a social product; in order to serve human well-being, intellectual property systems must respect and conform to human rights laws. According to the Committee, when systems fail to do so they risk infringing upon the human right to food and health, and to cultural participation and scientific benefits. In 2004 the General Assembly of WIPO adopted The Geneva Declaration on the Future of the World Intellectual Property Organization which argues that WIPO should "focus more on the needs of developing countries, and to view IP as one of many tools for development—not as an end in itself".
Who issued a document called "Human rights and intellectual property"?
****
The answer: the UN Committee on Economic, Social and Cultural Rights


The problem: Answer a question about this article:
In his Science of Logic (1812–1814) Hegel argues that finite qualities are not fully "real" because they depend on other finite qualities to determine them. Qualitative infinity, on the other hand, would be more self-determining and hence more fully real. Similarly finite natural things are less "real"—because they are less self-determining—than spiritual things like morally responsible people, ethical communities and God. So any doctrine, such as materialism, that asserts that finite qualities or natural objects are fully real is mistaken.
When was Science of Logic written?
****
The answer: 1812–1814


The problem: Answer a question about this article:
The Soviets also helped Germany to avoid British naval blockades by providing a submarine base, Basis Nord, in the northern Soviet Union near Murmansk. This also provided a refueling and maintenance location, and a takeoff point for raids and attacks on shipping. In addition, the Soviets provided Germany with access to the Northern Sea Route for both cargo ships and raiders (though only the commerce raider Komet used the route before the German invasion), which forced Britain to protect sea lanes in both the Atlantic and the Pacific.
What did the Germans use to avoid British blockades?
****
The answer:
a submarine base
