Problem: The city of Nanjing was razed after the Sui dynasty took over it. It renamed Shengzhou () in Tang dynasty and resuscitated during the late Tang.

Question: While there is some dispute as to the matter of influence, Popper had a long-standing and close friendship with economist Friedrich Hayek, who was also brought to the London School of Economics from Vienna. Each found support and similarities in the other's work, citing each other often, though not without qualification. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper, and in 1982 said, "...ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology."

The method of execution of federal prisoners for offenses under the Violent Crime Control and Law Enforcement Act of 1994 is that of the state in which the conviction took place. If the state has no death penalty, the judge must choose a state with the death penalty for carrying out the execution. For offenses under the Drug Kingpin Act of 1988, the method of execution is lethal injection. The Federal Correctional Complex in Terre Haute, Indiana is currently the home of the only death chamber for federal death penalty recipients in the United States, where inmates are put to death by lethal injection. The complex has so far been the only location used for federal executions post-Gregg. Timothy McVeigh and Juan Garza were put to death in June 2001, and Louis Jones, Jr. was put to death on March 18, 2003.
Under what federal statute are offenses punished by lethal injection?
A:
Drug Kingpin Act of 1988
