QUES: The first British patent for the use of asphalt/bitumen was 'Cassell's patent asphalte or bitumen' in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms, who worked with him on the introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Indeed, mastic pavements had been previously employed at Vauxhall by a competitor of Claridge, but without success.

QUES: The ASA standard underwent a major revision in 1960 with ASA PH2.5-1960, when the method to determine film speed was refined and previously applied safety factors against under-exposure were abandoned, effectively doubling the nominal speed of many black-and-white negative films. For example, an Ilford HP3 that had been rated at 200 ASA before 1960 was labeled 400 ASA afterwards without any change to the emulsion. Similar changes were applied to the DIN system with DIN 4512:1961-10 and the BS system with BS 1380:1963 in the following years.
In what year were big changes made to the ANSI?

ANS: 1960

QUES: An unconventional power succession system was established (rota system) whereby power was transferred to the eldest member of the ruling dynasty rather than from father to son, i.e. in most cases to the eldest brother of the ruler, fomenting constant hatred and rivalry within the royal family.[citation needed] Familicide was frequently deployed in obtaining power and can be traced particularly during the time of the Yaroslavichi rule (sons of Yaroslav) when the established system was skipped in the establishment of Vladimir II Monomakh as the Grand Prince of Kiev,[clarification needed] in turn creating major squabbles between Olegovichi from Chernihiv, Monomakhs from Pereyaslav, Izyaslavichi from Turov/Volhynia, and Polotsk Princes.[citation needed]
Who improved relations between the Olegovichi and Monomakhs?

ANS: unanswerable

QUES: According to the Omnipotence paradox or 'Paradox of the Stone', can God create a stone so heavy that he cannot lift it? Either he can or he can't. If he can't, the argument goes, then there is something that he cannot do, namely create the stone, and therefore he is not omnipotent. If he can, it continues, then there is also something that he cannot do, namely lift the stone, and therefore he is not omnipotent. Either way, then, God is not omnipotent. A being that is not omnipotent, though, is not God, according to many theological models. Such a God, therefore, does not exist. Several answers to this paradox have been proposed.
What question does the theological model paradox ask?
