In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Q: Which artist is listed  first, Context: Similarly, movies and television often revert to standard, clichéd snatches of classical music to convey refinement or opulence: some of the most-often heard pieces in this category include Bach´s Cello Suite No. 1, Mozart's Eine kleine Nachtmusik, Vivaldi's Four Seasons, Mussorgsky's Night on Bald Mountain (as orchestrated by Rimsky-Korsakov), and Rossini's William Tell Overture.

A: Bach

Q: What is a prerequisite for weight to play a factor in conductivity?, Context: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.

A: constant pressure and temperature

Q: What did Russia believe to be a large source of failure?, Context: The Crimean War marked the ascendancy of France to the position of pre-eminent power on the Continent,:411 the continued decline of the Ottoman Empire, and the beginning of a decline for Tsarist Russia. As Fuller notes, "Russia had been beaten on the Crimean peninsula, and the military feared that it would inevitably be beaten again unless steps were taken to surmount its military weakness." The Crimean War marks the demise of the Concert of Europe, the balance of power that had dominated Europe since the Congress of Vienna in 1815, and which had included France, Russia, Austria and the United Kingdom.

A:
military weakness
