Input: Read this: 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.
Question: As what did early scientists describe gossypol ?

Output: poisonous pigment

QUES: The collation of all known variants of a text is referred to as a variorum, namely a work of textual criticism whereby all variations and emendations are set side by side so that a reader can track how textual decisions have been made in the preparation of a text for publication. The Bible and the works of William Shakespeare have often been the subjects of variorum editions, although the same techniques have been applied with less frequency to many other works, such as Walt Whitman's Leaves of Grass, and the prose writings of Edward Fitzgerald.

What is the name for the collation of all unknown variants of a text?

QUES: In inorganic chemistry, hydrides can also serve as bridging ligands that link two metal centers in a coordination complex. This function is particularly common in group 13 elements, especially in boranes (boron hydrides) and aluminium complexes, as well as in clustered carboranes.
What group is briging ligands most common in?

ANS: group 13

The Super Slim model of PS3 has received positive reviews. Gaming website Spong praised the new Super Slim's quietness, stating "The most noticeable noise comes when the drive seeks a new area of the disc, such as when starting to load a game, and this occurs infrequently." They added that the fans are quieter than that of Slim, and went on to praise the new smaller, lighter size. Criticism was placed on the new disc loader, stating: "The cover can be moved by hand if you wish, there's also an eject button to do the work for you, but there is no software eject from the triangle button menus in the Xross Media Bar (XMB) interface. In addition, you have to close the cover by hand, which can be a bit fiddly if it's upright, and the PS3 won't start reading a disc unless you do [close the cover]." They also said there is no real drop in retail price.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What piece of the PS3 Super Slim's hardware did Spong say was too "fiddly"?
Ah, so.. disc loader

Question: The city proper is home to less than one-thirteenth of the population of South Florida. Miami is the 42nd-most populous city in the United States. The Miami metropolitan area, which includes Miami-Dade, Broward and Palm Beach counties, had a combined population of more than 5.5 million people, ranked seventh largest in the United States, and is the largest metropolitan area in the Southeastern United States. As of 2008[update], the United Nations estimates that the Miami Urban Agglomeration is the 44th-largest in the world.
Try to answer this question if possible: What fraction of the northern Florida population lives in Miami?
Answer: unanswerable

Context and question: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinumiridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems it is known that over such a timescale the many similar PtIr alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
What kind of alloy is never used to measure a kilogram?

unanswerable
