Problem: Baptists are individuals who comprise a group of Christian denominations and churches that subscribe to a doctrine that baptism should be performed only for professing believers (believer's baptism, as opposed to infant baptism), and that it must be done by complete immersion (as opposed to affusion or sprinkling). Other tenets of Baptist churches include soul competency (liberty), salvation through faith alone, Scripture alone as the rule of faith and practice, and the autonomy of the local congregation. Baptists recognize two ministerial offices, elders and deacons. Baptist churches are widely considered to be Protestant churches, though some Baptists disavow this identity.
What individuals subscribe to a doctrine that baptism should be performed only for professing believers?
The answer is the following: Baptists

Problem: Saint Helena was first settled by the English in 1659, and the island has a population of about 4,250 inhabitants, mainly descended from people from Britain settlers ("planters") and soldiers and slaves who were brought there from the beginning of settlement initially from Africa (the Cape Verde Islands, Gold Coast and west coast of Africa are mentioned in early records), then India and Madagascar. Eventually the planters felt there were too many slaves and no more were imported after 1792.
When was Saint Helena first settled?
The answer is the following: 1659

Problem: Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 90014,000 nanometers or 0.914 m) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to "see" one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature (hence the name).
What law states that infrared radiation is emitted by objects based on temperature?
The answer is the following:
the black body radiation law
