QUES: The Valencia Metro derailment occurred on 3 July 2006 at 1 pm. CEST (1100 UTC) between Jesús and Plaça d'Espanya stations on Line 1 of the Metrovalencia mass transit system. 43 people were killed and more than ten were seriously injured. It was not immediately clear what caused the crash. Both the Valencian government spokesman Vicente Rambla and Mayor Rita Barberá called the accident a "fortuitous" event. However, the trade union CC.OO. accused the authorities of "rushing" to say anything but admit that Line 1 is in a state of "constant deterioration" with a "failure to carry out maintenance".

QUES: In Du "Cubisme" Metzinger and Gleizes explicitly related the sense of time to multiple perspective, giving symbolic expression to the notion of ‘duration’ proposed by the philosopher Henri Bergson according to which life is subjectively experienced as a continuum, with the past flowing into the present and the present merging into the future. The Salon Cubists used the faceted treatment of solid and space and effects of multiple viewpoints to convey a physical and psychological sense of the fluidity of consciousness, blurring the distinctions between past, present and future. One of the major theoretical innovations made by the Salon Cubists, independently of Picasso and Braque, was that of simultaneity, drawing to greater or lesser extent on theories of Henri Poincaré, Ernst Mach, Charles Henry, Maurice Princet, and Henri Bergson. With simultaneity, the concept of separate spatial and temporal dimensions was comprehensively challenged. Linear perspective developed during the Renaissance was vacated. The subject matter was no longer considered from a specific point of view at a moment in time, but built following a selection of successive viewpoints, i.e., as if viewed simultaneously from numerous angles (and in multiple dimensions) with the eye free to roam from one to the other.
 The Cubist didn't use what kind of treatment of space and time?

Intercommunal violence erupted on December 21, 1963, when two Turkish Cypriots were killed at an incident involving the Greek Cypriot police. The violence resulted in the death of 364 Turkish and 174 Greek Cypriots, destruction of 109 Turkish Cypriot or mixed villages and displacement of 25,000-30,000 Turkish Cypriots. The crisis resulted in the end of the Turkish Cypriot involvement in the administration and their claiming that it had lost its legitimacy; the nature of this event is still controversial. In some areas, Greek Cypriots prevented Turkish Cypriots from travelling and entering government buildings, while some Turkish Cypriots willingly withdrew due to the calls of the Turkish Cypriot administration. Turkish Cypriots started living in enclaves; the republic's structure was changed unilaterally by Makarios and Nicosia was divided by the Green Line, with the deployment of UNFICYP troops.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In December of what year did intercommunal violence erupt?
Ah, so.. 1963


Question: Prior to 1948, approximately 800,000 Jews were living in lands which now make up the Arab world (excluding Israel). Of these, just under two-thirds lived in the French-controlled Maghreb region, 15–20% in the Kingdom of Iraq, approximately 10% in the Kingdom of Egypt and approximately 7% in the Kingdom of Yemen. A further 200,000 lived in Pahlavi Iran and the Republic of Turkey. Today, around 26,000 Jews live in Arab countries and around 30,000 in Iran and Turkey. A small-scale exodus had begun in many countries in the early decades of the 20th century, although the only substantial aliyah came from Yemen and Syria. The exodus from Arab and Muslim countries took place primarily from 1948. The first large-scale exoduses took place in the late 1940s and early 1950s, primarily in Iraq, Yemen and Libya, with up to 90% of these communities leaving within a few years. The peak of the exodus from Egypt occurred in 1956. The exodus in the Maghreb countries peaked in the 1960s. Lebanon was the only Arab country to see a temporary increase in its Jewish population during this period, due to an influx of refugees from other Arab countries, although by the mid-1970s the Jewish community of Lebanon had also dwindled. In the aftermath of the exodus wave from Arab states, an additional migration of Iranian Jews peaked in the 1980s when around 80% of Iranian Jews left the country.[citation needed]
Try to answer this question if possible: Prior to 1948, how many Jews were living in lands which now make up the Arab world (excluding Israel)?
Answer: 800,000
