QUES: A bantam is a small variety of domestic chicken, either a miniature version of a member of a standard breed, or a "true bantam" with no larger counterpart. The name derives from the town of Bantam in Java where European sailors bought the local small chickens for their shipboard supplies. Bantams may be a quarter to a third of the size of standard birds and lay similarly small eggs. They are kept by small-holders and hobbyists for egg production, use as broody hens, ornamental purposes, and showing.
What bird is unable to lay eggs due to the small size?

ANS: unanswerable

Rome had no separate priestly caste or class. The highest authority within a community usually sponsored its cults and sacrifices, officiated as its priest and promoted its assistants and acolytes. Specialists from the religious colleges and professionals such as haruspices and oracles were available for consultation. In household cult, the paterfamilias functioned as priest, and members of his familia as acolytes and assistants. Public cults required greater knowledge and expertise. The earliest public priesthoods were probably the flamines (the singular is flamen), attributed to king Numa: the major flamines, dedicated to Jupiter, Mars and Quirinus, were traditionally drawn from patrician families. Twelve lesser flamines were each dedicated to a single deity, whose archaic nature is indicated by the relative obscurity of some. Flamines were constrained by the requirements of ritual purity; Jupiter's flamen in particular had virtually no simultaneous capacity for a political or military career.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What authority in a community sponsored religious rites?
Ah, so.. highest

Question: The High Middle Ages was a period of tremendous expansion of population. The estimated population of Europe grew from 35 to 80 million between 1000 and 1347, although the exact causes remain unclear: improved agricultural techniques, the decline of slaveholding, a more clement climate and the lack of invasion have all been suggested. As much as 90 per cent of the European population remained rural peasants. Many were no longer settled in isolated farms but had gathered into small communities, usually known as manors or villages. These peasants were often subject to noble overlords and owed them rents and other services, in a system known as manorialism. There remained a few free peasants throughout this period and beyond, with more of them in the regions of Southern Europe than in the north. The practice of assarting, or bringing new lands into production by offering incentives to the peasants who settled them, also contributed to the expansion of population.
Try to answer this question if possible: What was the approximate population of Europe in 1347?
Answer: 80 million

Input: Read this: The British Royal Navy is constructing two new larger STOVL aircraft carriers, the Queen Elizabeth class, to replace the three Invincible-class carriers. The ships will be named HMS Queen Elizabeth and HMS Prince of Wales.
