Input: Punjab, Pakistan
As of June 2012[update], Pakistan's electricity problems were so severe that violent riots were taking place across Punjab. According to protesters, load shedding was depriving the cities of electricity 20–22 hours a day, causing businesses to go bust and making living extremely hard. Gujranwala, Toba Tek Singh, Faisalabad, Sialkot, Bahawalnagar and communities across Khanewal District saw widespread rioting and violence on Sunday 17 June 2012, with the houses of several members of parliament being attacked as well as the offices of regional energy suppliers Fesco, Gepco and Mepco being ransacked or attacked.

What kind of problem caused riots in June 2012?

Input: Tibet
In 821/822 CE Tibet and China signed a peace treaty. A bilingual account of this treaty, including details of the borders between the two countries, is inscribed on a stone pillar which stands outside the Jokhang temple in Lhasa. Tibet continued as a Central Asian empire until the mid-9th century, when a civil war over succession led to the collapse of imperial Tibet. The period that followed is known traditionally as the Era of Fragmentation, when political control over Tibet became divided between regional warlords and tribes with no dominant centralized authority.

Where does a bilingual account of Tibet and China's peace treaty exist?
Output: Jokhang temple in Lhasa

Input: Georgian architecture
Georgian architecture is the name given in most English-speaking countries to the set of architectural styles current between 1714 and 1830. It is eponymous for the first four British monarchs of the House of Hanover—George I, George II, George III, and George IV—who reigned in continuous succession from August 1714 to June 1830. The style was revived in the late 19th century in the United States as Colonial Revival architecture and in the early 20th century in Great Britain as Neo-Georgian architecture; in both it is also called Georgian Revival architecture. In America the term "Georgian" is generally used to describe all building from the period, regardless of style; in Britain it is generally restricted to buildings that are "architectural in intention", and have stylistic characteristics that are typical of the period, though that covers a wide range.

Who were the British monarchs of the House of Hanover from August 1714 to June 1830?
Output: George I, George II, George III, and George IV

Input: Mammal
If Mammalia is considered as the crown group, its origin can be roughly dated as the first known appearance of animals more closely related to some extant mammals than to others. Ambondro is more closely related to monotremes than to therian mammals while Amphilestes and Amphitherium are more closely related to the therians; as fossils of all three genera are dated about 167 million years ago in the Middle Jurassic, this is a reasonable estimate for the appearance of the crown group. The earliest known synapsid satisfying Kemp's definitions is Tikitherium, dated 225 Ma, so the appearance of mammals in this broader sense can be given this Late Triassic date. In any case, the temporal range of the group extends to the present day.

About what year do synapsid date back to?
Output:
225 Ma
