QUES: The reason for this is that a quantum disjunction, unlike the case for classical disjunction, can be true even when both of the disjuncts are false and this is, in turn, attributable to the fact that it is frequently the case, in quantum mechanics, that a pair of alternatives are semantically determinate, while each of its members are necessarily indeterminate. This latter property can be illustrated by a simple example. Suppose we are dealing with particles (such as electrons) of semi-integral spin (angular momentum) for which there are only two possible values: positive or negative. Then, a principle of indetermination establishes that the spin, relative to two different directions (e.g., x and y) results in a pair of incompatible quantities. Suppose that the state ɸ of a certain electron verifies the proposition "the spin of the electron in the x direction is positive." By the principle of indeterminacy, the value of the spin in the direction y will be completely indeterminate for ɸ. Hence, ɸ can verify neither the proposition "the spin in the direction of y is positive" nor the proposition "the spin in the direction of y is negative." Nevertheless, the disjunction of the propositions "the spin in the direction of y is positive or the spin in the direction of y is negative" must be true for ɸ. In the case of distribution, it is therefore possible to have a situation in which , while .

ANS: each of its members are necessarily indeterminate
QUES: In recent years, the city has experienced steady population growth, and has been faced with the issue of accommodating more residents. In 2006, after growing by 4,000 citizens per year for the previous 16 years, regional planners expected the population of Seattle to grow by 200,000 people by 2040. However, former mayor Greg Nickels supported plans that would increase the population by 60%, or 350,000 people, by 2040 and worked on ways to accommodate this growth while keeping Seattle's single-family housing zoning laws. The Seattle City Council later voted to relax height limits on buildings in the greater part of Downtown, partly with the aim to increase residential density in the city centre. As a sign of increasing inner-city growth, the downtown population crested to over 60,000 in 2009, up 77% since 1990.

What change in building heights did Seattle make to increase population density in its downtown ?
What is the answer?
ANS: height limits
QUES: The Augustan settlement built upon a cultural shift in Roman society. In the middle Republican era, even Scipio's tentative hints that he might be Jupiter's special protege sat ill with his colleagues. Politicians of the later Republic were less equivocal; both Sulla and Pompey claimed special relationships with Venus. Julius Caesar went further, and claimed her as his ancestress. Such claims suggested personal character and policy as divinely inspired; an appointment to priesthood offered divine validation. In 63 BC, Julius Caesar's appointment as pontifex maximus "signaled his emergence as a major player in Roman politics". Likewise, political candidates could sponsor temples, priesthoods and the immensely popular, spectacular public ludi and munera whose provision became increasingly indispensable to the factional politics of the Late Republic. Under the principate, such opportunities were limited by law; priestly and political power were consolidated in the person of the princeps ("first citizen").

In what year was Cesar made pontifex maximus?
What is the answer?
ANS:
63 BC
