Problem: Saint Barth%C3%A9lemy:

The marine life found here consists of anemones, urchins, sea cucumbers, and eels, which all live on the reefs along with turtles, conch and many varieties of marine fishes. The marine aquafauna is rich in conch, which has pearly-pink shells. Its meat is a favourite food supplement item and their shells are a collectors item. Other species of fish which are recorded close to the shore line in shallow waters are: sergeant majors, the blue chromis, brown chromis, surgeon fish; blue tangs and trumpet fish. On the shore are ghost crabs, which always live on the beach in small burrowed tunnels made in sand, and the hermit crabs, which live in land but lay eggs in water and which also eat garbage and sewerage. They spend some months in the sea during and after the hatching season.

Where do ghost crabs lay their eggs?

Problem: Coronis, was daughter of Phlegyas, King of the Lapiths. Pregnant with Asclepius, Coronis fell in love with Ischys, son of Elatus. A crow informed Apollo of the affair. When first informed he disbelieved the crow and turned all crows black (where they were previously white) as a punishment for spreading untruths. When he found out the truth he sent his sister, Artemis, to kill Coronis (in other stories, Apollo himself had killed Coronis). As a result, he also made the crow sacred and gave them the task of announcing important deaths. Apollo rescued the baby and gave it to the centaur Chiron to raise. Phlegyas was irate after the death of his daughter and burned the Temple of Apollo at Delphi. Apollo then killed him for what he did.
Who was the daughter of Phlegyas?

Answer: Coronis


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Capacity building is an ongoing problem experienced by NPOs for a number of reasons. Most rely on external funding (government funds, grants from charitable foundations, direct donations) to maintain their operations and changes in these sources of revenue may influence the reliability or predictability with which the organization can hire and retain staff, sustain facilities, create programs, or maintain tax-exempt status. For example, a university that sells research to for-profit companies may have tax exemption problems. In addition, unreliable funding, long hours and low pay can result in employee retention problems. During 2009, the US government acknowledged this critical need by the inclusion of the Nonprofit Capacity Building Program in the Serve America Act. Further efforts to quantify the scope of the sector and propose policy solutions for community benefit were included in the Nonprofit Sector and Community Solutions Act, proposed during 2010.
What problem did NPO's have in 2010?
A: unanswerable


Context and question: The government planned to voluntarily evacuate four million people—mostly women and children—from urban areas, including 1.4 million from London. It expected about 90% of evacuees to stay in private homes, and conducted an extensive survey to determine available space. Detailed preparations for transporting them were developed. A trial blackout was held on 10 August 1939, and when Germany invaded Poland on 1 September a blackout began at sunset. Lights would not be allowed after dark for almost six years, and the blackout became by far the most unpopular aspect of the war for civilians, more than rationing.:51,106 The relocation of the government and the civil service was also planned, but would only have occurred if necessary so as not to damage civilian morale.:33
Why did the government  and civil service not want to relocate during the war?
Answer: damage civilian morale


Question: By the late 1990s, blue LEDs became widely available. They have an active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN, called cladding layers. By varying the relative In/Ga fraction in the InGaN quantum wells, the light emission can in theory be varied from violet to amber. Aluminium gallium nitride (AlGaN) of varying Al/Ga fraction can be used to manufacture the cladding and quantum well layers for ultraviolet LEDs, but these devices have not yet reached the level of efficiency and technological maturity of InGaN/GaN blue/green devices. If un-alloyed GaN is used in this case to form the active quantum well layers, the device will emit near-ultraviolet light with a peak wavelength centred around 365 nm. Green LEDs manufactured from the InGaN/GaN system are far more efficient and brighter than green LEDs produced with non-nitride material systems, but practical devices still exhibit efficiency too low for high-brightness applications.[citation needed]
Is there an answer to this question: What LEDs are more efficient when produced from the InEGaN/GaEN systems than without?

Answer: unanswerable


QUES: The final son of Abd al-Malik to become caliph was Hisham (724–43), whose long and eventful reign was above all marked by the curtailment of military expansion. Hisham established his court at Resafa in northern Syria, which was closer to the Byzantine border than Damascus, and resumed hostilities against the Byzantines, which had lapsed following the failure of the last siege of Constantinople. The new campaigns resulted in a number of successful raids into Anatolia, but also in a major defeat (the Battle of Akroinon), and did not lead to any significant territorial expansion.

Who was the father of Hisham?
What is the answer?
ANS:
Abd al-Malik
