Problem: Tuberculosis:

Primary resistance occurs when a person becomes infected with a resistant strain of TB. A person with fully susceptible MTB may develop secondary (acquired) resistance during therapy because of inadequate treatment, not taking the prescribed regimen appropriately (lack of compliance), or using low-quality medication. Drug-resistant TB is a serious public health issue in many developing countries, as its treatment is longer and requires more expensive drugs. MDR-TB is defined as resistance to the two most effective first-line TB drugs: rifampicin and isoniazid. Extensively drug-resistant TB is also resistant to three or more of the six classes of second-line drugs. Totally drug-resistant TB is resistant to all currently used drugs. It was first observed in 2003 in Italy, but not widely reported until 2012, and has also been found in Iran and India. Bedaquiline is tentatively supported for use in multiple drug-resistant TB.

What's the minimum number of second-line medication classes your TB would have to resist to make it count as "extensively drug-resistant"?

Problem: Mali:

In 2007, about 48 percent of Malians were younger than 12 years old, 49 percent were 1564 years old, and 3 percent were 65 and older. The median age was 15.9 years. The birth rate in 2014 is 45.53 births per 1,000, and the total fertility rate (in 2012) was 6.4 children per woman. The death rate in 2007 was 16.5 deaths per 1,000. Life expectancy at birth was 53.06 years total (51.43 for males and 54.73 for females). Mali has one of the world's highest rates of infant mortality, with 106 deaths per 1,000 live births in 2007.

What was the death rate in 2014?

Problem: Genocide:

All signatories to the CPPCG are required to prevent and punish acts of genocide, both in peace and wartime, though some barriers make this enforcement difficult. In particular, some of the signatoriesnamely, Bahrain, Bangladesh, India, Malaysia, the Philippines, Singapore, the United States, Vietnam, Yemen, and former Yugoslaviasigned with the proviso that no claim of genocide could be brought against them at the International Court of Justice without their consent. Despite official protests from other signatories (notably Cyprus and Norway) on the ethics and legal standing of these reservations, the immunity from prosecution they grant has been invoked from time to time, as when the United States refused to allow a charge of genocide brought against it by former Yugoslavia following the 1999 Kosovo War.

Along with Cyprus, what other major signatory official protested the immunity of others from the prosecution of reservation?

A: unanswerable

Problem: Planck constant:

There are both practical and theoretical difficulties in determining h. The practical difficulties can be illustrated by the fact that the two most accurate methods, the watt balance and the X-ray crystal density method, do not appear to agree with one another. The most likely reason is that the measurement uncertainty for one (or both) of the methods has been estimated too low it is (or they are) not as precise as is currently believed but for the time being there is no indication which method is at fault.

Which method is at fault or the discrepancy?
