PROBLEM: In 1955, the diaries of Napoleon's valet, Louis Marchand, were published. His description of Napoleon in the months before his death led Sten Forshufvud in a 1961 paper in Nature to put forward other causes for his death, including deliberate arsenic poisoning. Arsenic was used as a poison during the era because it was undetectable when administered over a long period. Forshufvud, in a 1978 book with Ben Weider, noted that Napoleon's body was found to be remarkably well preserved when moved in 1840. Arsenic is a strong preservative, and therefore this supported the poisoning hypothesis. Forshufvud and Weider observed that Napoleon had attempted to quench abnormal thirst by drinking large amounts of orgeat syrup that contained cyanide compounds in the almonds used for flavouring.

SOLUTION: When were the diaries of Napoleon's valet published?

PROBLEM: Richard Nixon used national security as a basis for his expansion of power. He asserted, for example, that "the inherent power of the President to safeguard the security of the nation" authorized him to order a wiretap without a judge's warrant. Nixon also asserted that "executive privilege" shielded him from all legislative oversight; furthermore, he impounded federal funds (that is to say, he refused to spend money that Congress had appropriated for government programs). In the specific cases aforementioned, however, the Supreme Court ruled against Nixon. This was also because of an ongoing criminal investigation into the Watergate tapes, even though they acknowledged the general need for executive privilege. Since then, Nixon's successors have sometimes asserted that they may act in the interests of national security or that executive privilege shields them from Congressional oversight. Though such claims have in general been more limited than Nixon's, one may still conclude that the presidency's power has been greatly augmented since the eighteenth and nineteenth centuries.

SOLUTION: Under what basis did Richard Nixon assert an expansion of the power of the President?

PROBLEM: Four states in the modern era, Nebraska in 2008, New York and Kansas in 2004, and Massachusetts in 1984, had their statutes ruled unconstitutional by state courts. The death rows of New York and Massachusetts were disestablished, and attempts to restore the death penalty were unsuccessful. Kansas successfully appealed State v. Kleypas, the Kansas Supreme Court decision that declared the state's death penalty statute unconstitutional, to the United States Supreme Court. Nebraska's death penalty statute was rendered ineffective on February 8, 2008 when the required method, electrocution, was ruled unconstitutional by the Nebraska Supreme Court. In 2009, Nebraska enacted a bill that changed its method of execution to lethal injection.

SOLUTION:
In what year was Nebraska's death penalty statute ruled unconstitutional by a state court?
