Problem: 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.
What area of science did Al-Razi contribute to?
The answer is the following: chemistry and medicine

Problem: England qualified for the 1970 FIFA World Cup in Mexico as reigning champions, and reached the quarter-finals, where they were knocked out by West Germany. England had been 20 up, but were eventually beaten 32 after extra time. They failed in qualification for the 1974, leading to Ramsey's dismissal, and 1978 FIFA World Cups. Under Ron Greenwood, they managed to qualify for the 1982 FIFA World Cup in Spain (the first time competitively since 1962); despite not losing a game, they were eliminated in the second group stage.
Where did the 1982 FIFA World Cup take place?
The answer is the following: Spain

Problem: The Hephthalites (or Ephthalites), also known as the White Huns, were a nomadic confederation in Central Asia during the late antiquity period. The White Huns established themselves in modern-day Afghanistan by the first half of the 5th century. Led by the Hun military leader Toramana, they overran the northern region of Pakistan and North India. Toramana's son Mihirakula, a Saivite Hindu, moved up to near Pataliputra to the east and Gwalior to the central India. Hiuen Tsiang narrates Mihirakula's merciless persecution of Buddhists and destruction of monasteries, though the description is disputed as far as the authenticity is concerned. The Huns were defeated by the Indian kings Yasodharman of Malwa and Narasimhagupta in the 6th century. Some of them were driven out of India and others were assimilated in the Indian society.
What type of trib were the Hephthalites?
The answer is the following: nomadic confederation

Problem: Synapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million. The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal chemistry of their target cells in complex ways. A large number of synapses are dynamically modifiable; that is, they are capable of changing strength in a way that is controlled by the patterns of signals that pass through them. It is widely believed that activity-dependent modification of synapses is the brain's primary mechanism for learning and memory.
How many synapses does the human brain supposedly contain?
The answer is the following:
100 trillion synapses;
