Article: Ehrlich’s approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk. This work, also based in the testing of compounds available from the German dye industry, led to the development of Prontosil, the first representative of the sulfonamide class of antibiotics. Compared to arsphenamine, the sulfonamides had a broader spectrum of activity and were far less toxic, rendering them useful for infections caused by pathogens such as streptococci. In 1939, Domagk received the Nobel Prize in Medicine for this discovery. Nonetheless, the dramatic decrease in deaths from infectious diseases that occurred prior to World War II was primarily the result of improved public health measures such as clean water and less crowded housing, and the impact of anti-infective drugs and vaccines was significant mainly after World War II.

Question: Anti-infective drugs became more prominent after what war?
Ans: World War II


Here is a question about this article: After editing a book on John Stuart Mill's letters he planned to publish two books on the liberal order, The Constitution of Liberty and "The Creative Powers of a Free Civilization" (eventually the title for the second chapter of The Constitution of Liberty). He completed The Constitution of Liberty in May 1959, with publication in February 1960. Hayek was concerned "with that condition of men in which coercion of some by others is reduced as much as is possible in society". Hayek was disappointed that the book did not receive the same enthusiastic general reception as The Road to Serfdom had sixteen years before.
What is the answer to this question: What topic were Hayek's next two books going to cover?
****
So... the liberal order


The problem: Answer a question about this article:
In 525 BC, the powerful Achaemenid Persians, led by Cambyses II, began their conquest of Egypt, eventually capturing the pharaoh Psamtik III at the battle of Pelusium. Cambyses II then assumed the formal title of pharaoh, but ruled Egypt from his home of Susa in Persia (modern Iran), leaving Egypt under the control of a satrapy. The entire Twenty-seventh Dynasty of Egypt, from 525 BC to 402 BC, save for Petubastis III, was an entirely Persian ruled period, with the Achaemenid kings all being granted the title of pharaoh. A few temporarily successful revolts against the Persians marked the fifth century BC, but Egypt was never able to permanently overthrow the Persians.
Who took control of Egypt in 525 BC?
****
The answer: Achaemenid Persians

Question: Read this and answer the question

In 215 BC Philip, with his eye on Illyria, formed an alliance with Rome's enemy Hannibal of Carthage, which led to Roman alliances with the Achaean League, Rhodes and Pergamum. The First Macedonian War broke out in 212 BC, and ended inconclusively in 205 BC. Philip continued to wage war against Pergamon and Rhodes for control of the Aegean (204-200 BCE) and ignored Roman demands for non-intervention in Greece by invading Attica. In 198 BC, during the Second Macedonian War Philip was decisively defeated at Cynoscephalae by the Roman proconsul Titus Quinctius Flamininus and Macedon lost all its territories in Greece proper. Greece was now thoroughly brought into the Roman sphere of influence, though it retained nominal autonomy. The end of Antigonid Macedon came when Philip V's son, Perseus, was defeated and captured by the Romans in the Third Macedonian War (171–168 BCE).

When did the First Macedonian War end?
Answer: 205 BC


The French breech-loading rifle, the Chassepot, had a far longer range than the German needle gun; 1,500 yards (1,400 m) compared to 600 yd (550 m). The French also had an early machine-gun type weapon, the mitrailleuse, which could fire its thirty-seven barrels at a range of around 1,200 yd (1,100 m). It was developed in such secrecy, that little training with the weapon had occurred, leaving French gunners with no experience; the gun was treated like artillery and in this role it was ineffective. Worse still, once the small number of soldiers who had been trained how to use the new weapon became casualties, there were no replacements who knew how to operate the mitrailleuse.
Treating the mitrailleuse like what rendered it far less effective
artillery
