Problem: Copper:

Polyols, compounds containing more than one alcohol functional group, generally interact with cupric salts. For example, copper salts are used to test for reducing sugars. Specifically, using Benedict's reagent and Fehling's solution the presence of the sugar is signaled by a color change from blue Cu(II) to reddish copper(I) oxide. Schweizer's reagent and related complexes with ethylenediamine and other amines dissolve cellulose. Amino acids form very stable chelate complexes with copper(II). Many wet-chemical tests for copper ions exist, one involving potassium ferrocyanide, which gives a brown precipitate with copper(II) salts.

What is the name of the componds that has more than one alcohol functional group?
---
A: Polyols


Problem: University:

Although each institution is organized differently, nearly all universities have a board of trustees; a president, chancellor, or rector; at least one vice president, vice-chancellor, or vice-rector; and deans of various divisions. Universities are generally divided into a number of academic departments, schools or faculties. Public university systems are ruled over by government-run higher education boards. They review financial requests and budget proposals and then allocate funds for each university in the system. They also approve new programs of instruction and cancel or make changes in existing programs. In addition, they plan for the further coordinated growth and development of the various institutions of higher education in the state or country. However, many public universities in the world have a considerable degree of financial, research and pedagogical autonomy. Private universities are privately funded and generally have broader independence from state policies. However, they may have less independence from business corporations depending on the source of their finances.

What kind of board does a business commonly have?

A: unanswerable


Problem: Saint Barth%C3%A9lemy:

St. Barthélemy has a small airport known as Gustaf III Airport on the north coast of the island that is served by small regional commercial aircraft and charters. The nearest airport with a runway length sufficient to land a typical commercial jet airliner is on the neighboring island of Sint Maarten: Princess Juliana International Airport, which acts as a hub, providing connecting flights with regional carriers to St. Barthélemy. Several international airlines and domestic Caribbean airlines operate in this sector.

What type of planes most commonly land at Princess Juliana International Airport?
---
A: unanswerable


Problem: Richard Feynman:

Feynman devoted the latter half of his book What Do You Care What Other People Think? to his experience on the Rogers Commission, straying from his usual convention of brief, light-hearted anecdotes to deliver an extended and sober narrative. Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. For instance, NASA managers claimed that there was a 1 in 100,000 chance of a catastrophic failure aboard the shuttle, but Feynman discovered that NASA's own engineers estimated the chance of a catastrophe at closer to 1 in 200. He concluded that the space shuttle reliability estimate by NASA management was fantastically unrealistic, and he was particularly angered that NASA used these figures to recruit Christa McAuliffe into the Teacher-in-Space program. He warned in his appendix to the commission's report (which was included only after he threatened not to sign the report), "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled."

Which way did he avoid writing about his experience on the Rogers Commission?

A:
