QUES: According to the tradition, Virgil traveled to Greece in about 19 BC to revise the Aeneid. After meeting Augustus in Athens and deciding to return home, Virgil caught a fever while visiting a town near Megara. After crossing to Italy by ship, weakened with disease, Virgil died in Brundisium harbor on September 21, 19 BC. Augustus ordered Virgil's literary executors, Lucius Varius Rufus and Plotius Tucca, to disregard Virgil's own wish that the poem be burned, instead ordering it published with as few editorial changes as possible. As a result, the text of the Aeneid that exists may contain faults which Virgil was planning to correct before publication. However, the only obvious imperfections are a few lines of verse that are metrically unfinished (i.e. not a complete line of dactylic hexameter). Some scholars have argued that Virgil deliberately left these metrically incomplete lines for dramatic effect. Other alleged imperfections are subject to scholarly debate.
Where was the Aeneid first published?

QUES: H2 is a product of some types of anaerobic metabolism and is produced by several microorganisms, usually via reactions catalyzed by iron- or nickel-containing enzymes called hydrogenases. These enzymes catalyze the reversible redox reaction between H2 and its component two protons and two electrons. Creation of hydrogen gas occurs in the transfer of reducing equivalents produced during pyruvate fermentation to water. The natural cycle of hydrogen production and consumption by organisms is called the hydrogen cycle.
What is the natural cycle of hydrogen production and consumption by organisms called?

ANS: hydrogen cycle

QUES: As the universe evolves in time, more and more of its energy becomes trapped in irreversible states (i.e., as heat or other kinds of increases in disorder). This has been referred to as the inevitable thermodynamic heat death of the universe. In this heat death the energy of the universe does not change, but the fraction of energy which is available to do work through a heat engine, or be transformed to other usable forms of energy (through the use of generators attached to heat engines), grows less and less.
What is it referred to when more and more of energy becomes trapped in irreversible states?

ANS: inevitable thermodynamic heat death of the universe

QUES: Above the main portal there is generally a large window, like that at York Minster, or a group of windows such as those at Ripon Cathedral. In France there is generally a rose window like that at Reims Cathedral. Rose windows are also often found in the façades of churches of Spain and Italy, but are rarer elsewhere and are not found on the façades of any English Cathedrals. The gable is usually richly decorated with arcading or sculpture or, in the case of Italy, may be decorated with the rest of the façade, with polychrome marble and mosaic, as at Orvieto Cathedral.
What portion of Egyptian buildings are usually richly decorated with arcading or sculpture?
