It would appear that living organisms are remarkably inefficient (in the physical sense) in their use of the energy they receive (chemical energy or radiation), and it is true that most real machines manage higher efficiencies. In growing organisms the energy that is converted to heat serves a vital purpose, as it allows the organism tissue to be highly ordered with regard to the molecules it is built from. The second law of thermodynamics states that energy (and matter) tends to become more evenly spread out across the universe: to concentrate energy (or matter) in one specific place, it is necessary to spread out a greater amount of energy (as heat) across the remainder of the universe ("the surroundings").[note 3] Simpler organisms can achieve higher energy efficiencies than more complex ones, but the complex organisms can occupy ecological niches that are not available to their simpler brethren. The conversion of a portion of the chemical energy to heat at each step in a metabolic pathway is the physical reason behind the pyramid of biomass observed in ecology: to take just the first step in the food chain, of the estimated 124.7 Pg/a of carbon that is fixed by photosynthesis, 64.3 Pg/a (52%) are used for the metabolism of green plants, i.e. reconverted into carbon dioxide and heat.
What states that energy tends to become more evenly spread out across the universe?
The second law of thermodynamics


Input: Classical music
The family of instruments used, especially in orchestras, grew. A wider array of percussion instruments began to appear. Brass instruments took on larger roles, as the introduction of rotary valves made it possible for them to play a wider range of notes. The size of the orchestra (typically around 40 in the Classical era) grew to be over 100. Gustav Mahler's 1906 Symphony No. 8, for example, has been performed with over 150 instrumentalists and choirs of over 400.

What size of choirs have performed Gustav Mahler's 1906 Symphony No. 8?
Output: over 400


Input: Article: Kadamba (345 – 525 CE) was an ancient royal dynasty of Karnataka, India that ruled northern Karnataka and the Konkan from Banavasi in present-day Uttara Kannada district. At the peak of their power under King Kakushtavarma, the Kadambas of Banavasi ruled large parts of modern Karnataka state. The dynasty was founded by Mayurasharma in 345 CE which at later times showed the potential of developing into imperial proportions, an indication to which is provided by the titles and epithets assumed by its rulers. King Mayurasharma defeated the armies of Pallavas of Kanchi possibly with help of some native tribes. The Kadamba fame reached its peak during the rule of Kakusthavarma, a notable ruler with whom even the kings of Gupta Dynasty of northern India cultivated marital alliances. The Kadambas were contemporaries of the Western Ganga Dynasty and together they formed the earliest native kingdoms to rule the land with absolute autonomy. The dynasty later continued to rule as a feudatory of larger Kannada empires, the Chalukya and the Rashtrakuta empires, for over five hundred years during which time they branched into minor dynasties known as the Kadambas of Goa, Kadambas of Halasi and Kadambas of Hangal.

Now answer this question: Who founded the Kamdamba dynasty?

Output: Mayurasharma


Article: This technique of representing simultaneity, multiple viewpoints (or relative motion) is pushed to a high degree of complexity in Gleizes' monumental Le Dépiquage des Moissons (Harvest Threshing), exhibited at the 1912 Salon de la Section d'Or, Le Fauconnier’s Abundance shown at the Indépendants of 1911, and Delaunay's City of Paris, shown at the Indépendants in 1912. These ambitious works are some of the largest paintings in the history of Cubism. Léger’s The Wedding, also shown at the Salon des Indépendants in 1912, gave form to the notion of simultaneity by presenting different motifs as occurring within a single temporal frame, where responses to the past and present interpenetrate with collective force. The conjunction of such subject matter with simultaneity aligns Salon Cubism with early Futurist paintings by Umberto Boccioni, Gino Severini and Carlo Carrà; themselves made in response to early Cubism.

Question: Who painted the Wedding, show at Salon des Independants in 1912?
Ans: Léger


Here is a question about this article: Non-English terms for air defence include the German Flak (Fliegerabwehrkanone, "aircraft defence cannon", also cited as Flugabwehrkanone), whence English flak, and the Russian term Protivovozdushnaya oborona (Cyrillic: Противовозду́шная оборо́на), a literal translation of "anti-air defence", abbreviated as PVO. In Russian the AA systems are called zenitnye (i.e. "pointing to zenith") systems (guns, missiles etc.). In French, air defence is called DCA (Défense contre les aéronefs, "aéronef" being the generic term for all kind of airborne device (airplane, airship, balloon, missile, rocket, etc.)).
What is the answer to this question: What is the generic term for an airplane or rocket in French?
****
So... aéronef


Article: The Roman Republic (Latin: Res publica Romana; Classical Latin: [ˈreːs ˈpuːb.lɪ.ka roːˈmaː.na]) was the period of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world. During the first two centuries of its existence, the Roman Republic expanded through a combination of conquest and alliance, from central Italy to the entire Italian peninsula. By the following century, it included North Africa, Spain, and what is now southern France. Two centuries after that, towards the end of the 1st century BC, it included the rest of modern France, Greece, and much of the eastern Mediterranean. By this time, internal tensions led to a series of civil wars, culminating with the assassination of Julius Caesar, which led to the transition from republic to empire. The exact date of transition can be a matter of interpretation. Historians have variously proposed Julius Caesar's crossing of the Rubicon River in 49 BC, Caesar's appointment as dictator for life in 44 BC, and the defeat of Mark Antony and Cleopatra at the Battle of Actium in 31 BC. However, most use the same date as did the ancient Romans themselves, the Roman Senate's grant of extraordinary powers to Octavian and his adopting the title Augustus in 27 BC, as the defining event ending the Republic.

Question: What marked the beginning of the Roman Republic?
Ans:
the overthrow of the Roman Kingdom
