Russian border troops were stationed along the Tajik–Afghan border until summer 2005. Since the September 11, 2001 attacks, French troops have been stationed at the Dushanbe Airport in support of air operations of NATO's International Security Assistance Force in Afghanistan. United States Army and Marine Corps personnel periodically visit Tajikistan to conduct joint training missions of up to several weeks duration. The Government of India rebuilt the Ayni Air Base, a military airport located 15 km southwest of Dushanbe, at a cost of $70 million, completing the repairs in September 2010. It is now the main base of the Tajikistan air force. There have been talks with Russia concerning use of the Ayni facility, and Russia continues to maintain a large base on the outskirts of Dushanbe.

Marshall's words and future court decisions gave Congress much latitude in delegating powers. It was not until the 1930s that the Supreme Court held a delegation of authority unconstitutional. In a case involving the creation of the National Recovery Administration called A.L.A. Schechter Poultry Corp. v. United States, 295 U.S. 495 (1935), Congress could not authorize the president to formulate codes of "fair competition." It was held that Congress must set some standards governing the actions of executive officers. The Court, however, has deemed that phrases such as "just and reasonable," "public interest" and "public convenience" suffice.
In which case was Congress able to authorize the president to formulate codes?
A: unanswerable

In the 2010s, American jurisdictions have experienced a shortage of lethal injection drugs, due to anti-death penalty advocacy and low production volume. Hospira, the only U.S. manufacturer of sodium thiopental, stopped making the drug in 2011. The European Union has outlawed the export of any product that could be used in an execution; this has prevented executioners from using EU-manufactured anesthetics like propofol which are needed for general medical purposes. Another alternative, pentobarbital, is also only manufactured in the European Union, which has caused the Danish producer to restrict distribution to U.S. government customers.
 The EU outlawed the export of products that could never be used in what activity?
A: unanswerable

Karl Marx published the Communist Manifesto in February 1848, with little attention. However, a few days later the French Revolution of 1848 broke out, which replaced the monarchy of Louis Philippe with the Second French Republic. In June 1848, Paris workers, disenchanted with the new government, built barricades and raised red flags. The new government called in the French Army to put down the uprising, the first of many such confrontations between the army and the new worker's movements in Europe.
