The approaching era of jet travel, and a series of midair collisions (most notable was the 1956 Grand Canyon mid-air collision), prompted passage of the Federal Aviation Act of 1958. This legislation gave the CAA's functions to a new independent body, the Federal Aviation Agency. The act transferred air safety regulation from the CAB to the new FAA, and also gave the FAA sole responsibility for a common civil-military system of air navigation and air traffic control. The FAA's first administrator, Elwood R. Quesada, was a former Air Force general and adviser to President Eisenhower.
Who was the former general to President Eisenhower?
A: unanswerable

Being a city on the Ill and close to the Rhine, Strasbourg has always been an important centre of fluvial navigation, as is attested by archeological findings. In 1682 the Canal de la Bruche was added to the river navigations, initially to provide transport for sandstone from quarries in the Vosges for use in the fortification of the city. That canal has since closed, but the subsequent Canal du Rhone au Rhine, Canal de la Marne au Rhin and Grand Canal d'Alsace are still in use, as is the important activity of the Port autonome de Strasbourg. Water tourism inside the city proper attracts hundreds of thousands of tourists yearly.
Which canal attracts the fewest tourists?

Vaisesika metaphysical premises are founded on a form of atomism, that the reality is composed of four substances (earth, water, air, fire). Each of these four are of two types: atomic (paramanu) and composite. An atom is, according to Vaisesika scholars, that which is indestructible (anitya), indivisible, and has a special kind of dimension, called "small" (anu). A composite, in this philosophy, is defined to be anything which is divisible into atoms. Whatever human beings perceive is composite, while atoms are invisible. The Vaisesikas stated that size, form, truths and everything that human beings experience as a whole is a function of atoms, their number and their spatial arrangements, their guna (quality), karma (activity), samanya (commonness), visesa (particularity) and amavaya (inherence, inseparable connectedness of everything).
How many realities are there?
