Question: What subject was studied in Muzahim al-Pachachi's birthplace?

full_context: Document 1: History of science: In Babylonian astronomy, records of the motions of the stars, planets, and the moon are left on thousands of clay tablets created by scribes. Even today, astronomical periods identified by Mesopotamian proto-scientists are still widely used in Western calendars such as the solar year and the lunar month. Using these data they developed arithmetical methods to compute the changing length of daylight in the course of the year and to predict the appearances and disappearances of the Moon and planets and eclipses of the Sun and Moon. Only a few astronomers' names are known, such as that of Kidinnu, a Chaldean astronomer and mathematician. Kiddinu's value for the solar year is in use for today's calendars. Babylonian astronomy was "the first and highly successful attempt at giving a refined mathematical description of astronomical phenomena." According to the historian A. Aaboe, "all subsequent varieties of scientific astronomy, in the Hellenistic world, in India, in Islam, and in the West—if not indeed all subsequent endeavour in the exact sciences—depend upon Babylonian astronomy in decisive and fundamental ways."
Document 2: History of mathematics: Babylonian mathematics refers to any mathematics of the peoples of Mesopotamia (modern Iraq) from the days of the early Sumerians through the Hellenistic period almost to the dawn of Christianity. The majority of Babylonian mathematical work comes from two widely separated periods: The first few hundred years of the second millennium BC (Old Babylonian period), and the last few centuries of the first millennium BC (Seleucid period). It is named Babylonian mathematics due to the central role of Babylon as a place of study. Later under the Arab Empire, Mesopotamia, especially Baghdad, once again became an important center of study for Islamic mathematics.
Document 3: Abrar Hasan: He was born on July, 1935 in Kanpur, British India. He migrated to Karachi, Pakistan after the Partition of India.

He was appointed as an arbitrator by the International Court of Settlement in Belgium. Abrar Hasan has taught law at Pakistani law colleges and was Principal of Islamia Law College, Karachi, 1997-1998. His law firm, "Abrar Hasan and Company", has been in business since 1962. Abrar Hasan has written books on constitutional matters, and intent and interpretation of law. A few of his books are part of law curriculum in Pakistan. Pakistan Academy of Jurists, a non-profit organization he founded arranges meetings and seminars to educate people on Pakistani law and the international charter of human rights. Abrar Hasan has been part of Pakistani delegations to attend human rights conferences held in SAARC countries.
Document 4: Muzahim al-Pachachi: Born to a prominent family and graduated from the Baghdad School of Law he organized the Arab nationalist Cultural Club in Baghdad in 1912; its members included Hamdi al-Pachachi, Talib al-Naqib and Muhammad Ridha.
Document 5: History of science: In mathematics, the Persian mathematician Muhammad ibn Musa al-Khwarizmi gave his name to the concept of the algorithm, while the term algebra is derived from al-jabr, the beginning of the title of one of his publications. What is now known as Arabic numerals originally came from India, but Muslim mathematicians did make several refinements to the number system, such as the introduction of decimal point notation. Sabian mathematician Al-Battani (850-929) contributed to astronomy and mathematics, while Persian scholar Al-Razi contributed to chemistry and medicine.
Document 6: Al-Nasir: Al-Nasir was the son of Caliph Al-Mustadi and a Turkish "umm walad" called "Zumurrud" (Emerald). His reign was unusual for the rise of the futuwwa groups in his reign, connected to Baghdad's long-standing ayyarun. These urban social groups had long existed in Baghdad and elsewhere, and they were often involved in urban conflicts, especially sectarian riots. Al-Nasir made them into an instrument of his government, reorganizing them along Sufi lines and ideology.
Document 7: Mesopotamia: Mesopotamia is a historical region in West Asia situated within the Tigris -- Euphrates river system, in modern days roughly corresponding to most of Iraq plus Kuwait, the eastern parts of Syria, Southeastern Turkey, and regions along the Turkish -- Syrian and Iran -- Iraq borders.
Document 8: Muslim world: The Islamic Golden Age coincided with the Middle Ages in the Muslim world, starting with the rise of Islam and establishment of the first Islamic state in 622. The end of the age is variously given as 1258 with the Mongolian Sack of Baghdad, or 1492 with the completion of the Christian Reconquista of the Emirate of Granada in Al-Andalus, Iberian Peninsula. During the reign of the Abbasid caliph Harun ar-Rashid (786 to 809), the legendary House of Wisdom was inaugurated in Baghdad where scholars from various parts of the world sought to translate and gather all the known world's knowledge into Arabic. The Abbasids were influenced by the Quranic injunctions and hadiths, such as "the ink of a scholar is more holy than the blood of a martyr," that stressed the value of knowledge. The major Islamic capital cities of Baghdad, Cairo, and Córdoba became the main intellectual centers for science, philosophy, medicine, and education. During this period, the Muslim world was a collection of cultures; they drew together and advanced the knowledge gained from the ancient Greek, Roman, Persian, Chinese, Indian, Egyptian, and Phoenician civilizations.
Document 9: Muammar Gaddafi: Although theoretically a collegial body operating through consensus building, Gaddafi dominated the RCC, although some of the others attempted to constrain what they saw as his excesses. Gaddafi remained the government's public face, with the identities of the other RCC members only being publicly revealed on 10 January 1970. All young men from (typically rural) working and middle-class backgrounds, none had university degrees; in this way they were distinct from the wealthy, highly educated conservatives who previously governed the country.
Document 10: Ancient Near East: The ancient Near East was the home of early civilizations within a region roughly corresponding to the modern Middle East: Mesopotamia (modern Iraq, southeast Turkey, southwest Iran, northeastern Syria and Kuwait), ancient Egypt, ancient Iran (Elam, Media, Parthia and Persia), Anatolia / Asia Minor and Armenian Highlands (Turkey's Eastern Anatolia Region, Armenia, northwestern Iran, southern Georgia, and western Azerbaijan), the Levant (modern Syria, Lebanon, Palestine, Israel, and Jordan), Cyprus and the Arabian Peninsula. The ancient Near East is studied in the fields of Near Eastern archaeology and ancient history.
Document 11: History of science: From their beginnings in Sumer (now Iraq) around 3500 BC, the Mesopotamian people began to attempt to record some observations of the world with numerical data. But their observations and measurements were seemingly taken for purposes other than for elucidating scientific laws. A concrete instance of Pythagoras' law was recorded, as early as the 18th century BC: the Mesopotamian cuneiform tablet Plimpton 322 records a number of Pythagorean triplets (3,4,5) (5,12,13). ..., dated 1900 BC, possibly millennia before Pythagoras,  but an abstract formulation of the Pythagorean theorem was not.
Document 12: Nadim al-Pachachi: Nadim al-Pachachi (18 March 1914 – 29 February 1976) was the Secretary-General of OPEC from January 1971 until December 1972. Born in Baghdad during the Ottoman Empire, he received a doctorate in petroleum engineering and worked in the Romanian oil fields as a young man. He served as the Minister of Economy in the Iraqi government from 1952 until 1957. He was arrested during the 14 July Revolution in 1958.
Document 13: Malik Barkat Ali: Malik Barkat Ali was born in April 1885 in Lahore a city of Punjab, British India, to a lower middle class family. After education at the local high school, he won a scholarship to the famous Forman Christian College, in Lahore. After graduating from there he remained an Assistant Professor at this college from 1905 to 1907 and then passed the LLB Law examination, and was selected as a Junior Magistrate in the Punjab Service in 1908, working there until 1914, when he resigned because he had developed differences on principles with the authorities there.
Document 14: Ibrahim Shihata: At the age of 20, Ibrahim Shihata graduated with a BA in law from Cairo University Law School at the top of his class. He originally planned to continue his education in the United States, but then received an offer from the Conseil d’Etat to work as a legal advisor in the Ministry of Health.
Document 15: Sabit Damolla: Sabit Damolla Abdulbaqi was born in 1883, in county of Atush in the Kashgar vilayet, where he received religious education. In the 1920s, he graduated from Xinjiang Academy of Politics and Laws in Ürümqi (later becoming Xinjiang University), that was founded by Governor Yang Zengxin in 1924 and originally performed courses in Russian, Chinese and Uyghur. After completing university, he visited the Middle East, touring Saudi Arabia, Turkey and Egypt; he also visited the Soviet Union, where he continued his studies. In 1932 he returned to Xinjiang through India, where he joined Emir Muhammad Amin Bughra in preparing a rebellion in Khotan district. Sabit Damulla was convinced that the Islamic world was not interested in supporting Uyghur independence, and so he turned to the Great Powers instead.
