General Electric heavily contaminated the Hudson River with polychlorinated biphenyls (PCBs) between 1947-77. This pollution caused a range of harmful effects to wildlife and people who eat fish from the river or drink the water. In response to this contamination, activists protested in various ways. Musician Pete Seeger founded the Hudson River Sloop Clearwater and the Clearwater Festival to draw attention to the problem. The activism led to the site being designated by the EPA as one of the superfund sites requiring extensive cleanup. Other sources of pollution, including mercury contamination and sewage dumping, have also contributed to problems in the Hudson River watershed.
Who founded the Hudson River Sloop Clearwater and the Clearwater Festival to bring attention to the pollution caused by GE?
****
The answer: Pete Seeger

The Abbot of Monte Cassino, Desiderius sent envoys to Constantinople some time after 1066 to hire expert Byzantine mosaicists for the decoration of the rebuilt abbey church. According to chronicler Leo of Ostia the Greek artists decorated the apse, the arch and the vestibule of the basilica. Their work was admired by contemporaries but was totally destroyed in later centuries except two fragments depicting greyhounds (now in the Monte Cassino Museum). "The abbot in his wisdom decided that great number of young monks in the monastery should be thoroughly initiated in these arts" says the chronicler about the role of the Greeks in the revival of mosaic art in medieval Italy.
After what time did the Abbot of Monte Cassino send for Byzantine mosaicists?

The Soviet answer on 4 May admonished Tito and the Communist Party of Yugoslavia (CPY) for failing to admit and correct its mistakes, and went on to accuse them of being too proud of their successes against the Germans, maintaining that the Red Army had saved them from destruction. Tito's response on 17 May suggested that the matter be settled at the meeting of the Cominform to be held that June. However, Tito did not attend the second meeting of the Cominform, fearing that Yugoslavia was to be openly attacked. In 1949 the crisis nearly escalated into an armed conflict, as Hungarian and Soviet forces were massing on the northern Yugoslav frontier. On 28 June, the other member countries expelled Yugoslavia, citing "nationalist elements" that had "managed in the course of the past five or six months to reach a dominant position in the leadership" of the CPY. The assumption in Moscow was that once it was known that he had lost Soviet approval, Tito would collapse; 'I will shake my little finger and there will be no more Tito,' Stalin remarked. The expulsion effectively banished Yugoslavia from the international association of socialist states, while other socialist states of Eastern Europe subsequently underwent purges of alleged "Titoists". Stalin took the matter personally and arranged several assassination attempts on Tito, none of which succeeded. In a correspondence between the two leaders, Tito openly wrote:
What was the name of those purged in other socialist states in Eastern Europe?
****
The answer: Titoists

According to the canonical gospels, Jesus, whom Christians believe to be the Son of God as well as the Messiah (Christ), was arrested, tried, and sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans. Jesus was stripped of his clothing and offered wine mixed with gall to drink, before being crucified. He was then hung for six hours (according to Mark's Gospel) between two convicted thieves. During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" in three languages. They then divided his garments among them, but cast lots for his seamless robe. After Jesus' death they pierced his side with a spear to be certain that he had died. The Bible records seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred.
