Problem: Time:

Another solution to the problem of causality-based temporal paradoxes is that such paradoxes cannot arise simply because they have not arisen. As illustrated in numerous works of fiction, free will either ceases to exist in the past or the outcomes of such decisions are predetermined. As such, it would not be possible to enact the grandfather paradox because it is a historical fact that your grandfather was not killed before his child (your parent) was conceived. This view doesn't simply hold that history is an unchangeable constant, but that any change made by a hypothetical future time traveler would already have happened in his or her past, resulting in the reality that the traveler moves from. More elaboration on this view can be found in the Novikov self-consistency principle.

In several works of fiction, what ceases to exist in the past which causes decisions not to arise?

A: unanswerable

Problem: Earthworms are Oligochaetes that support terrestrial food chains both as prey and in some regions are important in aeration and enriching of soil. The burrowing of marine polychaetes, which may constitute up to a third of all species in near-shore environments, encourages the development of ecosystems by enabling water and oxygen to penetrate the sea floor. In addition to improving soil fertility, annelids serve humans as food and as bait. Scientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries. Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.
What annelids' ears are being studied by engineers?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The statement that Joseph "knew her not till she brought forth her first born son" (Matthew 1:25 DouayRheims) has been debated among scholars, with some saying that she did not remain a virgin and some saying that she was a perpetual virgin. Other scholars contend that the Greek word heos (i.e., until) denotes a state up to a point, but does not mean that the state ended after that point, and that Matthew 1:25 does not confirm or deny the virginity of Mary after the birth of Jesus. According to Biblical scholar Bart Ehrman the Hebrew word almah, meaning young woman of childbearing age, was translated into Greek as parthenos, which only means virgin, in Isaiah 7:14, which is commonly believed by Christians to be the prophecy of the Virgin Mary referred to in Matthew 1:23. While Matthew and Luke give differing versions of the virgin birth, John quotes the uninitiated Philip and the disbelieving Jews gathered at Galilee referring to Joseph as Jesus's father.
Which Gospel writer provided a version of the virgin birth that was different than Matthew's?
A: Luke

Question: In response to the 2007 United States Air Force nuclear weapons incident, Secretary of Defense Robert Gates accepted in June 2009 the resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T.

Schwartz, a former tactical airlift and special operations pilot was the first officer appointed to that position who did not have a background as a fighter or bomber pilot. The Washington Post reported in 2010 that General Schwartz began to dismantle the rigid class system of the USAF, particularly in the officer corps.

At this point, Fox whispered that there was "no loss of friendship". "I regret to say there is", Burke replied, "I have indeed made a great sacrifice; I have done my duty though I have lost my friend. There is something in the detested French constitution that envenoms every thing it touches". This provoked a reply from Fox, yet he was unable to give his speech for some time since he was overcome with tears and emotion, he appealed to Burke to remember their inalienable friendship, but also repeated his criticisms of Burke and uttered "unusually bitter sarcasms". This only aggravated the rupture between the two men. Burke demonstrated his separation from the party on 5 June 1791 by writing to Fitzwilliam, declining money from him.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Burke leave the party?
Ah, so..
unanswerable
