Problem: Karl Popper:

Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.

Problem: While asthma is a well recognized condition, there is not one universal agreed upon definition. It is defined by the Global Initiative for Asthma as "a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. The chronic inflammation is associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in the early morning. These episodes are usually associated with widespread but variable airflow obstruction within the lung that is often reversible either spontaneously or with treatment".
What does hyper-responsiveness at the cellular level cause?

Until 1917, it was possible for someone who was not a priest, but only in minor orders, to become a cardinal (see "lay cardinals", below), but they were enrolled only in the order of cardinal deacons. For example, in the 16th century, Reginald Pole was a cardinal for 18 years before he was ordained a priest. In 1917 it was established that all cardinals, even cardinal deacons, had to be priests, and, in 1962, Pope John XXIII set the norm that all cardinals be ordained as bishops, even if they are only priests at the time of appointment. As a consequence of these two changes, canon 351 of the 1983 Code of Canon Law requires that a cardinal be at least in the order of priesthood at his appointment, and that those who are not already bishops must receive episcopal consecration. Several cardinals aged over 80 or close to it when appointed have obtained dispensation from the rule of having to be a bishop. These were all appointed cardinal-deacons, but one of them, Roberto Tucci, lived long enough to exercise the right of option and be promoted to the rank of cardinal-priest.
In what year was it declared that Cardinals had to be bishops?
A: 1962

Context and question: By the late 2000s, Dell's "configure to order" approach of manufacturingdelivering individual PCs configured to customer specifications from its US facilities was no longer as efficient or competitive with high-volume Asian contract manufacturers as PCs became powerful low-cost commodities. Dell closed plants that produced desktop computers for the North American market, including the Mort Topfer Manufacturing Center in Austin, Texas (original location) and Lebanon, Tennessee (opened in 1999) in 2008 and early 2009, respectively. The desktop production plant in Winston-Salem, North Carolina, received US$280 million in incentives from the state and opened in 2005, but ceased operations in November 2010. Dell's contract with the state required them to repay the incentives for failing to meet the conditions, and they sold the North Carolina plant to Herbalife. Most of the work that used to take place in Dell's U.S. plants was transferred to contract manufacturers in Asia and Mexico, or some of Dell's own factories overseas. The Miami, Florida, facility of its Alienware subsidiary remains in operation, while Dell continues to produce its servers (its most profitable products) in Austin, Texas. On January 8, 2009, Dell announced the closure of its manufacturing plant in Limerick, Ireland, with the loss of 1,900 jobs and the transfer of production to its plant in odz in Poland.
What decade did Dell's manufacturing process become more efficient?
Answer: unanswerable

Question: The causes of the Franco-Prussian War are deeply rooted in the events surrounding the unification of Germany. In the aftermath of the AustroPrussian War of 1866, Prussia had annexed numerous territories and formed the North German Confederation. This new power destabilized the European balance of power established by the Congress of Vienna in 1815 after the Napoleonic Wars. Napoleon III, then the emperor of France, demanded compensations in Belgium and on the left bank of the Rhine to secure France's strategic position, which the Prussian chancellor, Otto von Bismarck, flatly refused. Prussia then turned its attention towards the south of Germany, where it sought to incorporate the southern German kingdoms, Bavaria, Wurttemberg, Baden and Hesse-Darmstadt, into a unified Prussia-dominated Germany. France was strongly opposed to any further alliance of German states, which would have significantly strengthened the Prussian military.
Is there an answer to this question: In the aftermath of the Austro-Prussian war, formed what group?

Answer: North German Confederation

Early recordings were made entirely acoustically, the sound being collected by a horn and piped to a diaphragm, which vibrated the cutting stylus. Sensitivity and frequency range were poor, and frequency response was very irregular, giving acoustic recordings an instantly recognizable tonal quality. A singer practically had to put his or her face in the recording horn. Lower-pitched orchestral instruments such as cellos and double basses were often doubled (or replaced) by louder wind instruments, such as tubas. Standard violins in orchestral ensembles were commonly replaced by Stroh violins, which became popular with recording studios.
How was the frequency response in early recordings?
A:
very irregular
