QUES: Further desertions of John's local allies at the beginning of 1203 steadily reduced John's freedom to manoeuvre in the region. He attempted to convince Pope Innocent III to intervene in the conflict, but Innocent's efforts were unsuccessful. As the situation became worse for John, he appears to have decided to have Arthur killed, with the aim of removing his potential rival and of undermining the rebel movement in Brittany. Arthur had initially been imprisoned at Falaise and was then moved to Rouen. After this, Arthur's fate remains uncertain, but modern historians believe he was murdered by John. The annals of Margam Abbey suggest that "John had captured Arthur and kept him alive in prison for some time in the castle of Rouen ... when John was drunk he slew Arthur with his own hand and tying a heavy stone to the body cast it into the Seine."[nb 7] Rumours of the manner of Arthur's death further reduced support for John across the region. Arthur's sister, Eleanor, who had also been captured at Mirebeau, was kept imprisoned by John for many years, albeit in relatively good conditions.

Who did John attempt to convince?

QUES: The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy. The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. For example, antibacterial selection for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the LuriaDelbruck experiment. Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains.

What is resistance to antibiotics a cause of?
What is the answer?
ANS: evolution
QUES: In Greece, copper was known by the name chalkos (). It was an important resource for the Romans, Greeks and other ancient peoples. In Roman times, it was known as aes Cyprium, aes being the generic Latin term for copper alloys and Cyprium from Cyprus, where much copper was mined. The phrase was simplified to cuprum, hence the English copper. Aphrodite and Venus represented copper in mythology and alchemy, because of its lustrous beauty, its ancient use in producing mirrors, and its association with Cyprus, which was sacred to the goddess. The seven heavenly bodies known to the ancients were associated with the seven metals known in antiquity, and Venus was assigned to copper.

In what area was copper first mined?
