Problem: Sexual orientation:

Though researchers generally believe that sexual orientation is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences, with biological factors involving a complex interplay of genetic factors and the early uterine environment, they favor biological models for the cause. They believe that sexual orientation is not a choice, and some of them believe that it is established at conception. That is, individuals do not choose to be homosexual, heterosexual, bisexual, or asexual. While current scientific investigation usually seeks to find biological explanations for the adoption of a particular sexual orientation, there are yet no replicated scientific studies supporting any specific biological etiology for sexual orientation. However, scientific studies have found a number of statistical biological differences between gay people and heterosexuals, which may result from the same underlying cause as sexual orientation itself.

What do they believe about sexual orientation?

A: not a choice, and some of them believe that it is established at conception.


Problem: Florida:

"By May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a thick wall of red mangroves spread mile after mile, some reaching as high as 70 feet (21 m), with intertwined and elevated roots making landing difficult. Very soon, 'many smokes' appeared 'along the whole coast', billowing against the sky, when the Native ancestors of the Seminole spotted the newcomers and spread the alarm by signal fires". The Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida.[full citation needed] Both the Spanish and French established settlements in Florida, with varying degrees of success. In 1559, Don Tristán de Luna y Arellano established a colony at present-day Pensacola, one of the first European settlements in the continental United States, but it was abandoned by 1561.

Problem: Economy of Greece:

Energy production in Greece is dominated by the Public Power Corporation (known mostly by its acronym ΔΕΗ, or in English DEI). In 2009 DEI supplied for 85.6% of all energy demand in Greece, while the number fell to 77.3% in 2010. Almost half (48%) of DEI's power output is generated using lignite, a drop from the 51.6% in 2009. Another 12% comes from Hydroelectric power plants and another 20% from natural gas. Between 2009 and 2010, independent companies' energy production increased by 56%, from 2,709 Gigawatt hour in 2009 to 4,232 GWh in 2010.

What percentage did independent companies' energy production increase between 2009 and 2010?

A:
56%
