Input: Read this: One check on a magistrate's power was his collegiality. Each magisterial office would be held concurrently by at least two people. Another such check was provocatio. Provocatio was a primordial form of due process. It was a precursor to habeas corpus. If any magistrate tried to use the powers of the state against a citizen, that citizen could appeal the decision of the magistrate to a tribune. In addition, once a magistrate's one-year term of office expired, he would have to wait ten years before serving in that office again. This created problems for some consuls and praetors, and these magistrates would occasionally have their imperium extended. In effect, they would retain the powers of the office (as a promagistrate), without officially holding that office.
Question: Who would a Roman go see in an attempt to reverse the decision of a magistrate?

Output: a tribune

Input: Read this: It seems to have been St Bernard of Clairvaux who, in the 12th century, explicitly raised the question of the Immaculate Conception. A feast of the Conception of the Blessed Virgin had already begun to be celebrated in some churches of the West. St Bernard blames the canons of the metropolitan church of Lyon for instituting such a festival without the permission of the Holy See. In doing so, he takes occasion to repudiate altogether the view that the conception of Mary was sinless. It is doubtful, however, whether he was using the term "conception" in the same sense in which it is used in the definition of Pope Pius IX. Bernard would seem to have been speaking of conception in the active sense of the mother's cooperation, for in his argument he says: "How can there be absence of sin where there is concupiscence (libido)?" and stronger expressions follow, showing that he is speaking of the mother and not of the child.
Question: Who began to query the position of the conception of Mary following the 11th century ?

Output: St Bernard of Clairvaux

Input: Read this: Edwin Chadwick's 1829 article, "Preventive police" in the London Review, argued that prevention ought to be the primary concern of a police body, which was not the case in practice. The reason, argued Chadwick, was that "A preventive police would act more immediately by placing difficulties in obtaining the objects of temptation." In contrast to a deterrent of punishment, a preventive police force would deter criminality by making crime cost-ineffective - "crime doesn't pay". In the second draft of his 1829 Police Act, the "object" of the new Metropolitan Police, was changed by Robert Peel to the "principal object," which was the "prevention of crime." Later historians would attribute the perception of England's "appearance of orderliness and love of public order" to the preventive principle entrenched in Peel's police system.
Question: What did Chadwick say police should be focused on?

Output: prevention

Input: Read this: Geology did not undergo systematic restructuring during the Scientific Revolution, but individual theorists made important contributions. Robert Hooke, for example, formulated a theory of earthquakes, and Nicholas Steno developed the theory of superposition and argued that fossils were the remains of once-living creatures. Beginning with Thomas Burnet's Sacred Theory of the Earth in 1681, natural philosophers began to explore the idea that the Earth had changed over time. Burnet and his contemporaries interpreted Earth's past in terms of events described in the Bible, but their work laid the intellectual foundations for secular interpretations of Earth history.
Question: What theory did Nicholas Steno discover?

Output:
the theory of superposition
