Problem: Crimean War:

In spring 1855, the allied British-French commanders decided to send an Anglo-French naval squadron into the Azov Sea to undermine Russian communications and supplies to besieged Sevastopol. On 12 May 1855, British-French warships entered the Kerch Strait and destroyed the coast battery of the Kamishevaya Bay. On 21 May 1855, the gunboats and armed steamers attacked the seaport of Taganrog, the most important hub near Rostov on Don. The vast amounts of food, especially bread, wheat, barley, and rye that were amassed in the city after the outbreak of war were prevented from being exported.

What did the British-French commanders send to disrupt Russian communications and supplies?

A: Anglo-French naval squadron

Problem: The earliest extant arguments that the world of experience is grounded in the mental derive from India and Greece. The Hindu idealists in India and the Greek Neoplatonists gave panentheistic arguments for an all-pervading consciousness as the ground or true nature of reality. In contrast, the Yogacara school, which arose within Mahayana Buddhism in India in the 4th century CE, based its "mind-only" idealism to a greater extent on phenomenological analyses of personal experience. This turn toward the subjective anticipated empiricists such as George Berkeley, who revived idealism in 18th-century Europe by employing skeptical arguments against materialism.
When did the Yogacara school end?

During World War II, San Diego became a major hub of military and defense activity, due to the presence of so many military installations and defense manufacturers. The city's population grew rapidly during and after World War II, more than doubling between 1930 (147,995) and 1950 (333,865). During the final months of the war, the Japanese had a plan to target multiple U.S. cities for biological attack, starting with San Diego. The plan was called "Operation Cherry Blossoms at Night" and called for kamikaze planes filled with fleas infected with plague (Yersinia pestis) to crash into civilian population centers in the city, hoping to spread plague in the city and effectively kill tens of thousands of civilians. The plan was scheduled to launch on September 22, 1945, but was not carried out because Japan surrendered five weeks earlier.
Why didn't the Japanese launch their planned attack on September 20, 1945?
A: unanswerable

Question: Czech continued to evolve and gain in regional importance for hundreds of years, and has been a literary language in the Slovak lands since the early fifteenth century. A biblical translation, the Kralice Bible, was published during the late sixteenth century (around the time of the King James and Luther versions) which was more linguistically conservative than either. The publication of the Kralice Bible spawned widespread nationalism, and in 1615 the government of Bohemia ruled that only Czech-speaking residents would be allowed to become full citizens or inherit goods or land. This, and the conversion of the Czech upper classes from the Habsburg Empire's Catholicism to Protestantism, angered the Habsburgs and helped trigger the Thirty Years' War (where the Czechs were defeated at the Battle of White Mountain). The Czechs became serfs; Bohemia's printing industry (and its linguistic and political rights) were dismembered, removing official regulation and support from its language. German quickly became the dominant language in Bohemia.
Is there an answer to this question: In what year did Germans become serfs?

Up until the middle of the 1980s it was assumed that infants could not encode, retain, and retrieve information. A growing body of research now indicates that infants as young as 6-months can recall information after a 24-hour delay. Furthermore, research has revealed that as infants grow older they can store information for longer periods of time; 6-month-olds can recall information after a 24-hour period, 9-month-olds after up to five weeks, and 20-month-olds after as long as twelve months. In addition, studies have shown that with age, infants can store information faster. Whereas 14-month-olds can recall a three-step sequence after being exposed to it once, 6-month-olds need approximately six exposures in order to be able to remember it.
What has shown that with age, infants can store information slower
A:
unanswerable
