In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.

Example Input: In ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Almost all life on Earth relies directly or indirectly on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae predominate in this role. Ecologists distinguish primary production as either net or gross, the former accounting for losses to processes such as cellular respiration, the latter not.
Example Output: define and compare gross primary production and net primary production

Example Input: Capitalism is an economic system based upon private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system, and competitive markets. In a capitalist market economy, decision-making and investment are determined by every owner of wealth, property or production ability in financial and capital markets, whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets.
Example Output: who owns the factors of production in capitalism

Example Input: According to Pausanias it was introduced by Hercules as a prize for the running race winner to honor his father Zeus. In the ancient Olympic Games there were no gold, silver, or bronze medals. There was only one winner per event, crowned with an olive wreath made of wild-olive leaves from a sacred tree near the temple of Zeus at Olympia. Olive wreaths were given out during the 2004 Summer Olympics in Athens in honor of the ancient tradition, because the games were being held in Greece.
Example Output:
what does the olive branch represent in the olympics
