QUES: In 1762, George III acquired Buckingham House and it was enlarged over the next 75 years. During the 18th century, London was dogged by crime, and the Bow Street Runners were established in 1750 as a professional police force. In total, more than 200 offences were punishable by death, including petty theft. Most children born in the city died before reaching their third birthday. The coffeehouse became a popular place to debate ideas, with growing literacy and the development of the printing press making news widely available; and Fleet Street became the centre of the British press.
What was the name of the police force established in London in 1750?

ANS: the Bow Street Runners

QUES: The second major event of the early reign of Abd al-Malik was the construction of the Dome of the Rock in Jerusalem. Although the chronology remains somewhat uncertain, the building seems to have been completed in 692, which means that it was under construction during the conflict with Ibn al-Zubayr. This had led some historians, both medieval and modern, to suggest that the Dome of the Rock was built as a destination for pilgrimage to rival the Kaaba, which was under the control of Ibn al-Zubayr.
What was the first major event of the early reign of Abd al-Mali?

ANS: unanswerable

QUES: Water splitting, in which water is decomposed into its component protons, electrons, and oxygen, occurs in the light reactions in all photosynthetic organisms. Some such organisms, including the alga Chlamydomonas reinhardtii and cyanobacteria, have evolved a second step in the dark reactions in which protons and electrons are reduced to form H2 gas by specialized hydrogenases in the chloroplast. Efforts have been undertaken to genetically modify cyanobacterial hydrogenases to efficiently synthesize H2 gas even in the presence of oxygen. Efforts have also been undertaken with genetically modified alga in a bioreactor.
How are these gases formed?

ANS:
by specialized hydrogenases in the chloroplast
