Input: Solar energy
A solar chimney (or thermal chimney, in this context) is a passive solar ventilation system composed of a vertical shaft connecting the interior and exterior of a building. As the chimney warms, the air inside is heated causing an updraft that pulls air through the building. Performance can be improved by using glazing and thermal mass materials in a way that mimics greenhouses.

What is a solar chimney?
Output: a passive solar ventilation system

Input: Szlachta
Significant legislative changes in the status of the szlachta, as defined by Robert Bideleux and Ian Jeffries, consist of its 1374 exemption from the land tax, a 1425 guarantee against the 'arbitrary arrests and/or seizure of property' of its members, a 1454 requirement that military forces and new taxes be approved by provincial Sejms, and statutes issued between 1496 and 1611 that prescribed the rights of commoners.

What were the statutes issued between 1496 and 1611 prescribed from?
Output: rights of commoners

Input: Szlachta
The first "free election" (Polish: "wolna elekcja") of a king took place in 1492. (To be sure, some earlier Polish kings had been elected with help from bodies such as that which put Casimir II on the throne, thereby setting a precedent for free elections.) Only senators voted in the 1492 free election, which was won by John I Albert. For the duration of the Jagiellonian Dynasty, only members of that royal family were considered for election; later, there would be no restrictions on the choice of candidates.

When did the first free election take place?
Output: 1492

Input: Brain
The SCN projects to a set of areas in the hypothalamus, brainstem, and midbrain that are involved in implementing sleep-wake cycles. An important component of the system is the reticular formation, a group of neuron-clusters scattered diffusely through the core of the lower brain. Reticular neurons send signals to the thalamus, which in turn sends activity-level-controlling signals to every part of the cortex. Damage to the reticular formation can produce a permanent state of coma.

Damage to the reticular formation can cause what?
Output:
state of coma
