Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:
Vietnam: The event was held in Ho Chi Minh City on April 29. Some 60 torchbearers carried the torch from the downtown Opera House to the Military Zone 7 Competition Hall stadium near Tan Son Nhat International Airport along an undisclosed route. Vietnam is involved in a territorial dispute with China (and other countries) for sovereignty of the Spratly and Paracel Islands; tensions have risen recently[when?] following reports that the Chinese government had established a county-level city named Sansha in the disputed territories, resulting in anti-Chinese demonstrations in December 2007 in Hanoi and Ho Chi Minh City. However to sustain its relationship with China the Vietnamese government has actively sought to head off protests during the torch relay, with Prime Minister Nguyen Tan Dung warning government agencies that "hostile forces" may try to disrupt the torch relay.
Where did the torch event begin in Vietnam?
A: the downtown Opera House
Problem: Please answer a question about the following article about Alloy:
When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a primary role in determining which mechanism will occur. When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent. This is called a substitutional alloy. Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal. The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix. Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.
Tin or zinc atoms in place of copper atoms create?
A: substitutional alloys
Problem: Please answer a question about the following article about Anthropology:
Political anthropology concerns the structure of political systems, looked at from the basis of the structure of societies. Political anthropology developed as a discipline concerned primarily with politics in stateless societies, a new development started from the 1960s, and is still unfolding: anthropologists started increasingly to study more "complex" social settings in which the presence of states, bureaucracies and markets entered both ethnographic accounts and analysis of local phenomena. The turn towards complex societies meant that political themes were taken up at two main levels. First of all, anthropologists continued to study political organization and political phenomena that lay outside the state-regulated sphere (as in patron-client relations or tribal political organization). Second of all, anthropologists slowly started to develop a disciplinary concern with states and their institutions (and of course on the relationship between formal and informal political institutions). An anthropology of the state developed, and it is a most thriving field today. Geertz' comparative work on "Negara", the Balinese state is an early, famous example.
The presence of states, bureaucracies and markets makes for what type of social setting?
A: "complex"
Problem: Please answer a question about the following article about Tuberculosis:
The Mantoux tuberculin skin test is often used to screen people at high risk for TB. Those who have been previously immunized may have a false-positive test result. The test may be falsely negative in those with sarcoidosis, Hodgkin's lymphoma, malnutrition, and most notably, active tuberculosis. Interferon gamma release assays (IGRAs), on a blood sample, are recommended in those who are positive to the Mantoux test. These are not affected by immunization or most environmental mycobacteria, so they generate fewer false-positive results. However, they are affected by M. szulgai, M. marinum, and M. kansasii. IGRAs may increase sensitivity when used in addition to the skin test, but may be less sensitive than the skin test when used alone.
What result might someone who has received a TB vaccination get from the Mantoux test?
A:
false-positive
