Problem: In his 1854 book "The Cruise of the Steam Yacht North Star" John Choules described Southampton thus: "I hardly know a town that can show a more beautiful Main Street than Southampton, except it be Oxford. The High Street opens from the quay, and under various names it winds in a gently sweeping line for one mile and a half, and is of very handsome width. The variety of style and color of material in the buildings affords an exhibition of outline, light and color, that I think is seldom equalled. The shops are very elegant, and the streets are kept exceedingly clean."
Choules complimented the streets of Southampton for being kept in what condition?
The answer is the following: clean

Problem: At least a few insects have nociceptors, cells that detect and transmit sensations of pain. This was discovered in 2003 by studying the variation in reactions of larvae of the common fruitfly Drosophila to the touch of a heated probe and an unheated one. The larvae reacted to the touch of the heated probe with a stereotypical rolling behavior that was not exhibited when the larvae were touched by the unheated probe. Although nociception has been demonstrated in insects, there is no consensus that insects feel pain consciously
When were nociceptors discovered?
The answer is the following: 2003
