The oldest brain to have been discovered was in Armenia in the Areni-1 cave complex. The brain, estimated to be over 5,000 years old, was found in the skull of a 12 to 14-year-old girl. Although the brains were shriveled, they were well preserved due to the climate found inside the cave.

Where was the oldest brain that was found?
Answer: Armenia

Problem: The plebeians had finally achieved political equality with the patricians. However, the plight of the average plebeian had not changed. A small number of plebeian families achieved the same standing that the old aristocratic patrician families had always had, but the new plebeian aristocrats became as uninterested in the plight of the average plebeian as the old patrician aristocrats had always been. The plebeians rebelled by leaving Rome and refusing to return until they had more rights. The patricians then noticed how much they needed the plebeians and accepted their terms. The plebeians then returned to Rome and continued their work.
Which group of people rebelled by vacating Rome?
The answer is the following: The plebeians

Modern Rajasthan includes most of Rajputana, which comprises the erstwhile nineteen princely states, two chiefships, and the British district of Ajmer-Merwara. Marwar (Jodhpur), Bikaner, Mewar (Chittorgarh), Alwar and Dhundhar (Jaipur) were some of the main Rajput princely states. Bharatpur and Dholpur were Jat princely states whereas Tonk was a princely state under a Muslim Nawab. Rajput families rose to prominence in the 6th century CE. The Rajputs put up a valiant resistance to the Islamic invasions and protected this land with their warfare and chivalry for more than 500 years. They also resisted Mughal incursions into India and thus contributed to their slower-than-anticipated access to the Indian subcontinent. Later, the Mughals, through skilled warfare, were able to get a firm grip on northern India, including Rajasthan. Mewar led other kingdoms in its resistance to outside rule. Most notably, Rana Sanga fought the Battle of Khanua against Babur, the founder of the Mughal empire.
What families rose to power in the 6th century?
Rajput families

Input: Hyderabad
Qutb Shahi architecture of the 16th and early 17th centuries followed classical Persian architecture featuring domes and colossal arches. The oldest surviving Qutb Shahi structure in Hyderabad is the ruins of Golconda fort built in the 16th century. The Charminar, Mecca Masjid, Charkaman and Qutb Shahi tombs are other existing structures of this period. Among these the Charminar has become an icon of the city; located in the centre of old Hyderabad, it is a square structure with sides 20 m (66 ft) long and four grand arches each facing a road. At each corner stands a 56 m (184 ft)-high minaret. Most of the historical bazaars that still exist were constructed on the street north of Charminar towards Golconda fort. The Charminar, Qutb Shahi tombs and Golconda fort are considered to be monuments of national importance in India; in 2010 the Indian government proposed that the sites be listed for UNESCO World Heritage status.:1118

What iconic historic structure is in the center of old Hyderabad?
Output: the Charminar

Input: Article: Dogs have lived and worked with humans in so many roles that they have earned the unique nickname, "man's best friend", a phrase used in other languages as well. They have been bred for herding livestock, hunting (e.g. pointers and hounds), rodent control, guarding, helping fishermen with nets, detection dogs, and pulling loads, in addition to their roles as companions. In 1957, a husky-terrier mix named Laika became the first animal to orbit the Earth.

Now answer this question: What year was the first dog sent into space?

Output: 1957

Problem: Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
What variables help the photographer produce the desired effect?
The answer is the following:
lighting, film speed, f-number (aperture size), and shutter speed (exposure time)
