In 1987, occupations and units with the primary role of preparing for direct involvement in combat on the ground or at sea were still closed to women: infantry, armoured corps, field artillery, air-defence artillery, signals, field engineers, and naval operations. On 5 February 1987, the Minister of National Defence created an office to study the impact of employing men and women in combat units. These trials were called Combat-Related Employment of Women.
Who created an office to study these effects?
****
The answer: the Minister of National Defence

Beyoncé is believed to have first started a relationship with Jay Z after a collaboration on "'03 Bonnie & Clyde", which appeared on his seventh album The Blueprint 2: The Gift & The Curse (2002). Beyoncé appeared as Jay Z's girlfriend in the music video for the song, which would further fuel speculation of their relationship. On April 4, 2008, Beyoncé and Jay Z were married without publicity. As of April 2014, the couple have sold a combined 300 million records together. The couple are known for their private relationship, although they have appeared to become more relaxed in recent years. Beyoncé suffered a miscarriage in 2010 or 2011, describing it as "the saddest thing" she had ever endured. She returned to the studio and wrote music in order to cope with the loss. In April 2011, Beyoncé and Jay Z traveled to Paris in order to shoot the album cover for her 4, and unexpectedly became pregnant in Paris.
When were Beyonce and Jay Z married?

The answer: April 4, 2008


The problem: Answer a question about this article:
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 .
