Question: The study of plants is vital because they underpin almost all animal life on Earth by generating a large proportion of the oxygen and food that provide humans and other organisms with aerobic respiration with the chemical energy they need to exist. Plants, algae and cyanobacteria are the major groups of organisms that carry out photosynthesis, a process that uses the energy of sunlight to convert water and carbon dioxide into sugars that can be used both as a source of chemical energy and of organic molecules that are used in the structural components of cells. As a by-product of photosynthesis, plants release oxygen into the atmosphere, a gas that is required by nearly all living things to carry out cellular respiration. In addition, they are influential in the global carbon and water cycles and plant roots bind and stabilise soils, preventing soil erosion. Plants are crucial to the future of human society as they provide food, oxygen, medicine, and products for people, as well as creating and preserving soil.
Try to answer this question if possible: What vital element is a byproduct of photosynthesis?
Answer: oxygen
Question: Other public festivals were not required by the calendar, but occasioned by events. The triumph of a Roman general was celebrated as the fulfillment of religious vows, though these tended to be overshadowed by the political and social significance of the event. During the late Republic, the political elite competed to outdo each other in public display, and the ludi attendant on a triumph were expanded to include gladiator contests. Under the Principate, all such spectacular displays came under Imperial control: the most lavish were subsidised by emperors, and lesser events were provided by magistrates as a sacred duty and privilege of office. Additional festivals and games celebrated Imperial accessions and anniversaries. Others, such as the traditional Republican Secular Games to mark a new era (saeculum), became imperially funded to maintain traditional values and a common Roman identity. That the spectacles retained something of their sacral aura even in late antiquity is indicated by the admonitions of the Church Fathers that Christians should not take part.
Try to answer this question if possible: Who paid for the most lavish of festival events?
Answer: emperors

Question: Jews originated as a national and religious group in the Middle East during the second millennium BCE, in the part of the Levant known as the Land of Israel. The Merneptah Stele appears to confirm the existence of a people of Israel, associated with the god El, somewhere in Canaan as far back as the 13th century BCE. The Israelites, as an outgrowth of the Canaanite population, consolidated their hold with the emergence of the Kingdom of Israel, and the Kingdom of Judah. Some consider that these Canaanite sedentary Israelites melded with incoming nomadic groups known as 'Hebrews'. Though few sources in the Bible mention the exilic periods in detail, the experience of diaspora life, from the Ancient Egyptian rule over the Levant, to Assyrian Captivity and Exile, to Babylonian Captivity and Exile, to Seleucid Imperial rule, to the Roman occupation, and the historical relations between Israelites and the homeland, became a major feature of Jewish history, identity and memory.
