Problem: Rajasthan:

The main industries are mineral based, agriculture based, and textile based. Rajasthan is the second largest producer of polyester fibre in India. The Pali and Bhilwara District produces more cloth than Bhiwandi, Maharashtra and the bhilwara is the largest city in suitings production and export and Pali is largest city in cotton and polyster in blouse pieces and rubia production and export. Several prominent chemical and engineering companies are located in the city of Kota, in southern Rajasthan. Rajasthan is pre-eminent in quarrying and mining in India. The Taj Mahal was built from the white marble which was mined from a town called Makrana. The state is the second largest source of cement in India. It has rich salt deposits at Sambhar, copper mines at Khetri, Jhunjhunu, and zinc mines at Dariba, Zawar mines and Rampura Aghucha (opencast) near Bhilwara. Dimensional stone mining is also undertaken in Rajasthan. Jodhpur sandstone is mostly used in monuments, important buildings and residential buildings. This stone is termed as "chittar patthar". Jodhpur leads in Handicraft and Guar Gum industry. Rajasthan is also a part of the Mumbai-Delhi Industrial corridor is set to benefit economically. The State gets 39% of the DMIC, with major districts of Jaipur, Alwar, Kota and Bhilwara benefiting.

What type of mines are in Bhilwara?

Problem: Qing dynasty:

The Guangxu Emperor died on November 14, 1908, and on November 15, 1908, Cixi also died. Rumors held that she or Yuan Shikai ordered trusted eunuchs to poison the Guangxu Emperor, and an autopsy conducted nearly a century later confirmed lethal levels of arsenic in his corpse. Puyi, the oldest son of Zaifeng, Prince Chun, and nephew to the childless Guangxu Emperor, was appointed successor at the age of two, leaving Zaifeng with the regency. This was followed by the dismissal of General Yuan Shikai from his former positions of power. In April 1911 Zaifeng created a cabinet in which there were two vice-premiers. Nonetheless, this cabinet was also known by contemporaries as "The Royal Cabinet" because among the thirteen cabinet members, five were members of the imperial family or Aisin Gioro relatives. This brought a wide range of negative opinions from senior officials like Zhang Zhidong. The Wuchang Uprising of October 10, 1911, led to the creation of a new central government, the Republic of China, in Nanjing with Sun Yat-sen as its provisional head. Many provinces soon began "separating" from Qing control. Seeing a desperate situation unfold, the Qing government brought Yuan Shikai back to military power. He took control of his Beiyang Army to crush the revolution in Wuhan at the Battle of Yangxia. After taking the position of Prime Minister and creating his own cabinet, Yuan Shikai went as far as to ask for the removal of Zaifeng from the regency. This removal later proceeded with directions from Empress Dowager Longyu.

What year was the Republic of China created?
---
A: 1911

Problem: Karl Popper:

Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.

According to Popper, what resolves conflicting hypotheses and observations in the long run?
---
A: the collective judgment of scientists

Problem: Umayyad Caliphate:

Marwan was succeeded by his son, Abd al-Malik (685705), who reconsolidated Umayyad control of the caliphate. The early reign of Abd al-Malik was marked by the revolt of Al-Mukhtar, which was based in Kufa. Al-Mukhtar hoped to elevate Muhammad ibn al-Hanafiyyah, another son of Ali, to the caliphate, although Ibn al-Hanafiyyah himself may have had no connection to the revolt. The troops of al-Mukhtar engaged in battles both with the Umayyads in 686, defeating them at the river Khazir near Mosul, and with Ibn al-Zubayr in 687, at which time the revolt of al-Mukhtar was crushed. In 691, Umayyad troops reconquered Iraq, and in 692 the same army captured Mecca. Ibn al-Zubayr was killed in the attack.

Who was the father of Muhammad ibn al-Hanafiyyah?
---
A:
Ali
