PlayStation Plus (commonly abbreviated PS+ and occasionally referred to as PSN Plus) is a premium PlayStation Network subscription service that was officially unveiled at E3 2010 by Jack Tretton, President and CEO of SCEA. Rumors of such service had been in speculation since Kaz Hirai's announcement at TGS 2009 of a possible paid service for PSN but with the current PSN service still available. Launched alongside PS3 firmware 3.40 and PSP firmware 6.30 on June 29, 2010, the paid-for subscription service provides users with enhanced services on the PlayStation Network, on top of the current PSN service which is still available with all of its features. These enhancements include the ability to have demos, game and system software updates download automatically to PlayStation 3. Subscribers also get early or exclusive access to some betas, game demos, premium downloadable content and other PlayStation Store items. North American users also get a free subscription to Qore. Users may choose to purchase either a one-year or a three-month subscription to PlayStation Plus.
How is PlayStation Plus never abbreviated?
A: unanswerable

The Atlantic coast of the United States is low, with minor exceptions. The Appalachian Highland owes its oblique northeast-southwest trend to crustal deformations which in very early geological time gave a beginning to what later came to be the Appalachian mountain system. This system had its climax of deformation so long ago (probably in Permian time) that it has since then been very generally reduced to moderate or low relief. It owes its present-day altitude either to renewed elevations along the earlier lines or to the survival of the most resistant rocks as residual mountains. The oblique trend of this coast would be even more pronounced but for a comparatively modern crustal movement, causing a depression in the northeast resulting in an encroachment of the sea upon the land. Additionally, the southeastern section has undergone an elevation resulting in the advance of the land upon the sea.
The of Appalachian Mountains are low today because of modern what?
A: unanswerable

In 2004, NIST researchers presented evidence that an isotropic non-crystalline metallic phase (dubbed "q-glass") could be grown from the melt. This phase is the first phase, or "primary phase," to form in the Al-Fe-Si system during rapid cooling. Interestingly, experimental evidence indicates that this phase forms by a first-order transition. Transmission electron microscopy (TEM) images show that the q-glass nucleates from the melt as discrete particles, which grow spherically with a uniform growth rate in all directions. The diffraction pattern shows it to be an isotropic glassy phase. Yet there is a nucleation barrier, which implies an interfacial discontinuity (or internal surface) between the glass and the melt.
What is q-glass?
A: an isotropic non-crystalline metallic phase

As the premiers did not come to an agreement on this question, the Parliamentary Council was supposed to address this issue. Its provisions are reflected in Article 29. There was a binding provision for a new delimitation of the federal territory: the Federal Territory must be revised ... (paragraph 1). Moreover, in territories or parts of territories whose affiliation with a Land had changed after 8 May 1945 without a referendum, people were allowed to petition for a revision of the current status within a year after the promulgation of the Basic Law (paragraph 2). If at least one tenth of those entitled to vote in Bundestag elections were in favour of a revision, the federal government had to include the proposal into its legislation. Then a referendum was required in each territory or part of a territory whose affiliation was to be changed (paragraph 3). The proposal should not take effect if within any of the affected territories a majority rejected the change. In this case, the bill had to be introduced again and after passing had to be confirmed by referendum in the Federal Republic as a whole (paragraph 4). The reorganization should be completed within three years after the Basic Law had come into force (paragraph 6).
What was required in each territory or part of a territory whose affiliation was to be changed?
A:
a referendum
