Here is a question about this article: The nervous system is large relative to the bird's size. The most developed part of the brain is the one that controls the flight-related functions, while the cerebellum coordinates movement and the cerebrum controls behaviour patterns, navigation, mating and nest building. Most birds have a poor sense of smell with notable exceptions including kiwis, New World vultures and tubenoses. The avian visual system is usually highly developed. Water birds have special flexible lenses, allowing accommodation for vision in air and water. Some species also have dual fovea. Birds are tetrachromatic, possessing ultraviolet (UV) sensitive cone cells in the eye as well as green, red and blue ones. This allows them to perceive ultraviolet light, which is involved in courtship. Birds have specialized light-sensing cells deep in their brains that respond to light without input from eyes or other sensory neurons. These photo-receptive cells in the hypothalamus are involved in detecting the longer days of spring, and thus regulate breeding activities.
What is the answer to this question: What regulates breeding activities?

So... photo-receptive cells in


Here is a question about this article: Throughout the 18th century, the watchword of translators was ease of reading. Whatever they did not understand in a text, or thought might bore readers, they omitted. They cheerfully assumed that their own style of expression was the best, and that texts should be made to conform to it in translation. For scholarship they cared no more than had their predecessors, and they did not shrink from making translations from translations in third languages, or from languages that they hardly knew, or—as in the case of James Macpherson's "translations" of Ossian—from texts that were actually of the "translator's" own composition.
What is the answer to this question: What did James Macpherson "translate" from?
****
So... own composition


Here is a question about this article: It seems to have been St Bernard of Clairvaux who, in the 12th century, explicitly raised the question of the Immaculate Conception. A feast of the Conception of the Blessed Virgin had already begun to be celebrated in some churches of the West. St Bernard blames the canons of the metropolitan church of Lyon for instituting such a festival without the permission of the Holy See. In doing so, he takes occasion to repudiate altogether the view that the conception of Mary was sinless. It is doubtful, however, whether he was using the term "conception" in the same sense in which it is used in the definition of Pope Pius IX. Bernard would seem to have been speaking of conception in the active sense of the mother's cooperation, for in his argument he says: "How can there be absence of sin where there is concupiscence (libido)?" and stronger expressions follow, showing that he is speaking of the mother and not of the child.
What is the answer to this question: Who began to query the position of the conception of Mary following the 11th century ?

So...
St Bernard of Clairvaux
