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

Input: Consider Input: What did his thinking conflict with?, Context: In the early 11th century, the Muslim physicist Ibn al-Haytham (Alhacen or Alhazen) discussed space perception and its epistemological implications in his Book of Optics (1021), he also rejected Aristotle's definition of topos (Physics IV) by way of geometric demonstrations and defined place as a mathematical spatial extension. His experimental proof of the intromission model of vision led to changes in the understanding of the visual perception of space, contrary to the previous emission theory of vision supported by Euclid and Ptolemy. In "tying the visual perception of space to prior bodily experience, Alhacen unequivocally rejected the intuitiveness of spatial perception and, therefore, the autonomy of vision. Without tangible notions of distance and size for correlation, sight can tell us next to nothing about such things."

Output: Aristotle's definition of topos


Input: Consider Input: What buildings were usually chosen to be burned to the ground?, Context: In the 1970s, the Bronx was plagued by a wave of arson. The burning of buildings was predominantly in the poorest communities, like the South Bronx. The most common explanation of what occurred was that landlords decided to burn their low property-value buildings and take the insurance money as it was more lucrative to get insurance money than to refurbish or sell a building in a severely distressed area. The Bronx became identified with a high rate of poverty and unemployment, which was mainly a persistent problem in the South Bronx.

Output: low property-value buildings


Input: Consider Input: Where might have Arabian tradition of henna come from?, Context: Additionally, henna is an important part of Somali culture. It is worn by Somali women on their hands, arms, feet and neck during weddings, Eid, Ramadan, and other festive occasions. Somali henna designs are similar to those in the Arabian peninsula, often featuring flower motifs and triangular shapes. The palm is also frequently decorated with a dot of henna and the fingertips are dipped in the dye. Henna parties are usually held before the wedding takes place. Somali women have likewise traditionally applied kohl (kuul) to their eyes. Usage of the eye cosmetic in the Horn region is believed to date to the ancient Land of Punt.


Output: ancient Land of Punt
