[Q]: What is the answer for the question: What gas would have led to a sudden greenhouse effect? from the following article ? The impact would have caused a megatsunami over 100 metres (330 ft) tall that would have reached all the way to what are now Texas and Florida. The height of the tsunami was limited by the relatively shallow sea in the area of the impact; in deep ocean it would have been 4.6 kilometres (2.9 mi) tall. A cloud of super-heated dust, ash and steam would have spread from the crater as the impactor burrowed underground in less than a second. Excavated material along with pieces of the impactor, ejected out of the atmosphere by the blast, would have been heated to incandescence upon re-entry, broiling the Earth's surface and possibly igniting wildfires; meanwhile, colossal shock waves would have triggered global earthquakes and volcanic eruptions. Fossil evidence for an instantaneous die-off of diverse animals was found in a soil layer only 10 centimetres (3.9 in) thick in New Jersey some 5,000 kilometres (3,100 mi) away from the impact site, indicating that death and burial under debris occurred suddenly and quickly over wide distances on land.The emission of dust and particles could have covered the entire surface of the Earth for several years, possibly a decade, creating a harsh environment for living things. The shock production of carbon dioxide caused by the destruction of carbonate rocks would have led to a sudden greenhouse effect. Over a decade or longer, sunlight would have been blocked from reaching the surface of the Earth by the dust particles in the atmosphere, cooling the surface dramatically. Photosynthesis by plants would also have been interrupted, affecting the entire food chain. A model of the event developed by Lomax et al. (2001) suggests that net primary productivity (NPP) rates may have increased to higher than pre-impact levels over the long term because of the high carbon dioxide concentrations.In February 2008, a team of researchers led by Sean Gulick at the University of Texas at Austin's Jackson School of Geosciences used seismic images of the crater to determine that the impactor...

[Q]: What is the answer for the question: What is the first name of the person who had guns in his pockets? from the following article ? By the time of the third plate, Tom Nero has progressed from the mistreatment of animals to theft and murder. Having encouraged his pregnant lover, Ann Gill, to rob and leave her mistress, he murders the girl when she meets him. The murder is shown to be particularly brutal: her neck, wrist, and index finger are almost severed. Her trinket box and the goods she had stolen lie on the ground beside her, and the index finger of her partially severed hand points to the words "God's Revenge against Murder" written on a book that, along with the Book of Common Prayer, has fallen from the box. A woman searching Nero's pockets uncovers pistols, a number of pocket watchesevidence of his having turned to highway robbery (as Tom Idle did in Industry and Idleness), and a letter from Ann Gill which reads: Dear TommyMy mistress has been the best of women to me, and my conscience flies in my face as often as I think of wronging her; yet I am resolved to venture body and soul to do as you would have me, so do not fail to meet me as you said you would, for I will bring along with me all the things I can lay my hands on. So no more at present; but I remain yours till death. Ann Gill. The spelling is perfect and while this is perhaps unrealistic, Hogarth deliberately avoids any chance of the scene becoming comical. A discarded envelope is addressed "To Thos Nero at Pinne...". Ronald Paulson sees a parallel between the lamb beaten to death in the Second Stage and the defenceless girl murdered here. Below the print, the text claims that Nero, if not repentant, is at least stunned by his actions: Various features in the print are meant to intensify the feelings of dread: the murder takes place in a graveyard, said to be St Pancras but suggested by John Ireland to resemble Marylebone; an owl and a bat fly around the scene; the moon shines down on the crime; the clock strikes one for the end of the witching hour. The composition of the image may allude to Anthony van Dyck's The Arrest of Christ. A lone Good Samaritan appears...

[Q]: What is the answer for the question: What is the last name of the person who used a stanza from"Wie schon leuchtet der Morgenstern" (1599)? from the following article ? Johann Sebastian Bach composed the church cantata Erschallet, ihr Lieder, erklinget, ihr Saiten! (Ring out, you songs; sound, you strings!), BWV 172, in Weimar for Pentecost Sunday in 1714. Bach led the first performance on 20 May 1714 in the Schlosskirche, the court chapel in the ducal Schloss. Erschallet, ihr Lieder is an early work in a genre to which he later contributed complete cantata cycles for all occasions of the liturgical year. Bach was appointed Konzertmeister in Weimar in the spring of 1714, a position that called for the performance of a church cantata each month. He composed Erschallet, ihr Lieder as the third cantata in the series, to a text probably written by court poet Salomon Franck. The text reflects different aspects of the Holy Spirit. The librettist included a quotation from the day's prescribed Gospel reading in the only recitative, and for the closing chorale he used a stanza from Philipp Nicolai's hymn "Wie schon leuchtet der Morgenstern" (1599). The work is in six movements, and scored for four vocal soloists, four-part choir, three trumpets, timpani, oboe, bassoon and a string orchestra of two violins, two violas, and basso continuo. The orchestra for the holiday occasion is festive compared to the two works previously composed in Weimar. The cantata opens with a chorus, followed by the recitative, in which words spoken by Jesus are sung by the bass as the vox Christi (voice of Christ). A bass aria with trumpets addresses the Trinity, and a tenor aria then describes the Spirit that was present at the Creation. This is followed by an intimate duet of the Soul (soprano) and the Spirit (alto), to which an oboe plays the ornamented melody of Martin Luther's hymn "Komm, Heiliger Geist, Herre Gott" and a solo cello provides the bass line. The theme of intimacy between God and Man is developed further in the following chorale, after which Bach specified an unusual repeat of the opening chorus. While Bach served as Thomaskantor director of church music in Leipzig from 1723, he...
