Problem: Military history of the United States:

After the costly U.S. involvement in World War I, isolationism grew within the nation. Congress refused membership in the League of Nations, and in response to the growing turmoil in Europe and Asia, the gradually more restrictive Neutrality Acts were passed, which were intended to prevent the U.S. from supporting either side in a war. President Franklin D. Roosevelt sought to support Britain, however, and in 1940 signed the Lend-Lease Act, which permitted an expansion of the "cash and carry" arms trade to develop with Britain, which controlled the Atlantic sea lanes.

Which UK President sought to circumvent Neutrality acts to aid Britain?

Problem: Hunter-gatherer:

To this day, most hunter-gatherers have a symbolically structured sexual division of labour. However, it is true that in a small minority of cases, women hunt the same kind of quarry as men, sometimes doing so alongside men. The best-known example are the Aeta people of the Philippines. According to one study, "About 85% of Philippine Aeta women hunt, and they hunt the same quarry as men. Aeta women hunt in groups and with dogs, and have a 31% success rate as opposed to 17% for men. Their rates are even better when they combine forces with men: mixed hunting groups have a full 41% success rate among the Aeta." Among the Ju'/hoansi people of Namibia, women help men track down quarry. Women in the Australian Martu also primarily hunt small animals like lizards to feed their children and maintain relations with other women.

Among the Ju'/hoansi women of China, women help men track down what?

Problem: Tuberculosis:

Diagnosing active tuberculosis based only on signs and symptoms is difficult, as is diagnosing the disease in those who are immunosuppressed. A diagnosis of TB should, however, be considered in those with signs of lung disease or constitutional symptoms lasting longer than two weeks. A chest X-ray and multiple sputum cultures for acid-fast bacilli are typically part of the initial evaluation. Interferon- release assays and tuberculin skin tests are of little use in the developing world. IGRA have similar limitations in those with HIV.

What kind of cultures test for HIV?
