In 1937 over 100 people died after ingesting "Elixir Sulfanilamide" manufactured by S.E. Massengill Company of Tennessee. The product was formulated in diethylene glycol, a highly toxic solvent that is now widely used as antifreeze. Under the laws extant at that time, prosecution of the manufacturer was possible only under the technicality that the product had been called an "elixir", which literally implied a solution in ethanol. In response to this episode, the U.S. Congress passed the Federal Food, Drug, and Cosmetic Act of 1938, which for the first time required pre-market demonstration of safety before a drug could be sold, and explicitly prohibited false therapeutic claims.
Who manufactured "Cosmetic Elixir"?

Capital punishment has existed in Tennessee at various times since statehood. Before 1913 the method of execution was hanging. From 1913 to 1915 there was a hiatus on executions but they were reinstated in 1916 when electrocution became the new method. From 1972 to 1978, after the Supreme Court ruled (Furman v. Georgia) capital punishment unconstitutional, there were no further executions. Capital punishment was restarted in 1978, although those prisoners awaiting execution between 1960 and 1978 had their sentences mostly commuted to life in prison. From 1916 to 1960 the state executed 125 inmates. For a variety of reasons there were no further executions until 2000. Since 2000, Tennessee has executed six prisoners and has 73 prisoners on death row (as of April 2015).
How many prisoners did Tennessee execute between 1916 and 1960?
A: 125

The cottonseed which remains after the cotton is ginned is used to produce cottonseed oil, which, after refining, can be consumed by humans like any other vegetable oil. The cottonseed meal that is left generally is fed to ruminant livestock; the gossypol remaining in the meal is toxic to monogastric animals. Cottonseed hulls can be added to dairy cattle rations for roughage. During the American slavery period, cotton root bark was used in folk remedies as an abortifacient, that is, to induce a miscarriage. Gossypol was one of the many substances found in all parts of the cotton plant and it was described by the scientists as 'poisonous pigment'. It also appears to inhibit the development of sperm or even restrict the mobility of the sperm. Also, it is thought to interfere with the menstrual cycle by restricting the release of certain hormones.
For what is cottonseed used after it is separate from root bark?
A: unanswerable
