The problem: Answer a question about this article:
Capacitors, especially ceramic capacitors, and older designs such as paper capacitors, can absorb sound waves resulting in a microphonic effect. Vibration moves the plates, causing the capacitance to vary, in turn inducing AC current. Some dielectrics also generate piezoelectricity. The resulting interference is especially problematic in audio applications, potentially causing feedback or unintended recording. In the reverse microphonic effect, the varying electric field between the capacitor plates exerts a physical force, moving them as a speaker. This can generate audible sound, but drains energy and stresses the dielectric and the electrolyte, if any.
What value of a capacitor is varied when vibration moves the conducting plates?
****
The answer: the capacitance

Problem: Please answer a question about the following article about Hellenistic period:
The decisive engagement of the war came when Lysimachus invaded and overran much of western Anatolia, but was soon isolated by Antigonus and Demetrius near Ipsus in Phrygia. Seleucus arrived in time to save Lysimachus and utterly crushed Antigonus at the Battle of Ipsus in 301 BCE. Seleucus' war elephants proved decisive, Antigonus was killed, and Demetrius fled back to Greece to attempt to preserve the remnants of his rule there by recapturing a rebellious Athens. Meanwhile, Lysimachus took over Ionia, Seleucus took Cilicia, and Ptolemy captured Cyprus.
Who lost in the Battle of Ipsus?
A: Antigonus

By the early 20th century, mass civil disorder had begun in China, and it was growing continuously. To overcome such problems, Empress Dowager Cixi issued an imperial edict in 1901 calling for reform proposals from the governors-general and governors and initiated the era of the dynasty's "New Policies", also known as the "Late Qing Reform". The edict paved the way for the most far-reaching reforms in terms of their social consequences, including the creation of a national education system and the abolition of the imperial examinations in 1905.

When were imperial examinations halted?
Answer: 1905

Problem: Under New York State's gradual abolition act of 1799, children of slave mothers were born to be eventually liberated but were held in indentured servitude until their mid-to-late twenties. Together with slaves freed by their masters after the Revolutionary War and escaped slaves, a significant free-black population gradually developed in Manhattan. Under such influential United States founders as Alexander Hamilton and John Jay, the New York Manumission Society worked for abolition and established the African Free School to educate black children. It was not until 1827 that slavery was completely abolished in the state, and free blacks struggled afterward with discrimination. New York interracial abolitionist activism continued; among its leaders were graduates of the African Free School. The city's black population reached more than 16,000 in 1840.
When was slavery completely outlawed in the state of New York?
The answer is the following: 1827

West's controversial incident the following year at the 2009 MTV Video Music Awards was arguably his biggest controversy, and led to widespread outrage throughout the music industry. During the ceremony, West crashed the stage and grabbed the microphone from winner Taylor Swift in order to proclaim that, instead, Beyonce's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time". He was subsequently withdrawn from the remainder of the show for his actions. West's tour with Lady Gaga was cancelled in response to the controversy, and it was suggested that the incident was partially responsible for 808s & Heartbreak's lack of nominations at the 52nd Grammy Awards.
Which artist was Kanye supposed to tour with, but couldn't due to the Taylor Swift controversy?
Lady Gaga

Here is a question about this article: During World War II, Hayek began the 'Abuse of Reason' project. His goal was to show how a number of then-popular doctrines and beliefs had a common origin in some fundamental misconceptions about the social science. In his philosophy of science, which has much in common with that of his good friend Karl Popper, Hayek was highly critical of what he termed scientism: a false understanding of the methods of science that has been mistakenly forced upon the social sciences, but that is contrary to the practices of genuine science. Usually, scientism involves combining the philosophers' ancient demand for demonstrative justification with the associationists' false view that all scientific explanations are simple two-variable linear relationships.
What is the answer to this question: When did Hayek start working on Abuse of Reason?
****
So...
During World War II
