Problem: Ibn Sina subsequently settled at Rey, in the vicinity of modern Tehran, the home town of Rhazes; where Majd Addaula, a son of the last Buwayhid emir, was nominal ruler under the regency of his mother (Seyyedeh Khatun). About thirty of Ibn Sina's shorter works are said to have been composed in Rey. Constant feuds which raged between the regent and her second son, Shams al-Daula, however, compelled the scholar to quit the place. After a brief sojourn at Qazvin he passed southwards to Hamadan where Shams al-Daula, another Buwayhid emir, had established himself. At first, Ibn Sina entered into the service of a high-born lady; but the emir, hearing of his arrival, called him in as medical attendant, and sent him back with presents to his dwelling. Ibn Sina was even raised to the office of vizier. The emir decreed that he should be banished from the country. Ibn Sina, however, remained hidden for forty days in sheikh Ahmed Fadhel's house, until a fresh attack of illness induced the emir to restore him to his post. Even during this perturbed time, Ibn Sina persevered with his studies and teaching. Every evening, extracts from his great works, the Canon and the Sanatio, were dictated and explained to his pupils. On the death of the emir, Ibn Sina ceased to be vizier and hid himself in the house of an apothecary, where, with intense assiduity, he continued the composition of his works.
Ibn Sina left Rey and moved southwards to what city?
The answer is the following: Hamadan

Problem: Bacteria are further divided into lithotrophs that use inorganic electron donors and organotrophs that use organic compounds as electron donors. Chemotrophic organisms use the respective electron donors for energy conservation (by aerobic/anaerobic respiration or fermentation) and biosynthetic reactions (e.g., carbon dioxide fixation), whereas phototrophic organisms use them only for biosynthetic purposes. Respiratory organisms use chemical compounds as a source of energy by taking electrons from the reduced substrate and transferring them to a terminal electron acceptor in a redox reaction. This reaction releases energy that can be used to synthesise ATP and drive metabolism. In aerobic organisms, oxygen is used as the electron acceptor. In anaerobic organisms other inorganic compounds, such as nitrate, sulfate or carbon dioxide are used as electron acceptors. This leads to the ecologically important processes of denitrification, sulfate reduction, and acetogenesis, respectively.
In what organisms is oxygen used as eelectron acceptor?
The answer is the following: anaerobic organisms

Problem: Kerry is a Roman Catholic, and is said to carry a religious rosary, a prayer book, and a St. Christopher medal (the patron saint of travelers) when he campaigned. While Kerry is personally against abortion, he supports a woman's legal right to have one. Discussing his faith, Kerry said, "I thought of being a priest. I was very religious while at school in Switzerland. I was an altar boy and prayed all the time. I was very centered around the Mass and the church." He also said that the Letters of Paul (Apostle Paul) moved him the most, stating that they taught him to "not feel sorry for myself."
What religion is Kerry?
The answer is the following: Roman Catholic

Problem: The words of the comic playwright P. Terentius Afer reverberated across the Roman world of the mid-2nd century BCE and beyond. Terence, an African and a former slave, was well placed to preach the message of universalism, of the essential unity of the human race, that had come down in philosophical form from the Greeks, but needed the pragmatic muscles of Rome in order to become a practical reality. The influence of Terence's felicitous phrase on Roman thinking about human rights can hardly be overestimated. Two hundred years later Seneca ended his seminal exposition of the unity of humankind with a clarion-call:
What was the name of the main belief Terence offered
The answer is the following:
universalism
