Most of the enlargement of the primate brain comes from a massive expansion of the cerebral cortex, especially the prefrontal cortex and the parts of the cortex involved in vision. The visual processing network of primates includes at least 30 distinguishable brain areas, with a complex web of interconnections. It has been estimated that visual processing areas occupy more than half of the total surface of the primate neocortex. The prefrontal cortex carries out functions that include planning, working memory, motivation, attention, and executive control. It takes up a much larger proportion of the brain for primates than for other species, and an especially large fraction of the human brain.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The prefrontal cortex is the largest in what animals?
Ah, so.. primates

State banquets also take place in the Ballroom; these formal dinners are held on the first evening of a state visit by a foreign head of state. On these occasions, for up to 170 guests in formal "white tie and decorations", including tiaras, the dining table is laid with the Grand Service, a collection of silver-gilt plate made in 1811 for the Prince of Wales, later George IV. The largest and most formal reception at Buckingham Palace takes place every November when the Queen entertains members of the diplomatic corps. On this grand occasion, all the state rooms are in use, as the royal family proceed through them, beginning at the great north doors of the Picture Gallery. As Nash had envisaged, all the large, double-mirrored doors stand open, reflecting the numerous crystal chandeliers and sconces, creating a deliberate optical illusion of space and light.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): For whom was the Grand Service made?
Ah, so.. the Prince of Wales

In the late eighteenth- and early nineteenth-century Germany, three pioneer physical educators – Johann Friedrich GutsMuths (1759–1839) and Friedrich Ludwig Jahn (1778–1852) – created exercises for boys and young men on apparatus they had designed that ultimately led to what is considered modern gymnastics. Don Francisco Amorós y Ondeano, was born on February 19, 1770 in Valence and died on August 8, 1848 in Paris. He was a Spanish colonel, and the first person to introduce educative gymnastic in France. Jahn promoted the use of parallel bars, rings and high bar in international competition.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the exercises lead to?
Ah, so..
to what is considered modern gymnastics
