Please answer this: Question: "Which method of keeping asphalt soft has the biggest impact on our planet?" Context: "Asphalt/bitumen is typically stored and transported at temperatures around 150 C (302 F). Sometimes diesel oil or kerosene are mixed in before shipping to retain liquidity; upon delivery, these lighter materials are separated out of the mixture. This mixture is often called "bitumen feedstock", or BFS. Some dump trucks route the hot engine exhaust through pipes in the dump body to keep the material warm. The backs of tippers carrying asphalt/bitumen, as well as some handling equipment, are also commonly sprayed with a releasing agent before filling to aid release. Diesel oil is no longer used as a release agent due to environmental concerns." Answer:
++++++++
Answer: Diesel oil

Please answer this: Question: "With what event did the Investiture Controversy end?" Context: "Monastic reform inspired change in the secular church. The ideals that it was based upon were brought to the papacy by Pope Leo IX (pope 10491054), and provided the ideology of the clerical independence that led to the Investiture Controversy in the late 11th century. This involved Pope Gregory VII (pope 107385) and Emperor Henry IV, who initially clashed over episcopal appointments, a dispute that turned into a battle over the ideas of investiture, clerical marriage, and simony. The emperor saw the protection of the Church as one of his responsibilities as well as wanting to preserve the right to appoint his own choices as bishops within his lands, but the papacy insisted on the Church's independence from secular lords. These issues remained unresolved after the compromise of 1122 known as the Concordat of Worms. The dispute represents a significant stage in the creation of a papal monarchy separate from and equal to lay authorities. It also had the permanent consequence of empowering German princes at the expense of the German emperors." Answer:
++++++++
Answer: Concordat of Worms

Please answer this: Question: "How did the conflict end?"

During his tenure, Sharon carried out his plan to unilaterally withdraw from the Gaza Strip and also spearheaded the construction of the Israeli West Bank barrier, ending the Intifada. By this time 1,100 Israelis had been killed, mostly in suicide bombings. The Palestinian fatalities, by 30 April 2008, reached 4,745 killed by Israeli security forces, 44 killed by Israeli civilians, and 577 killed by Palestinians." Answer:
