Problem: Please answer a question about the following article about Capacitor:
The capacitance of certain capacitors decreases as the component ages. In ceramic capacitors, this is caused by degradation of the dielectric. The type of dielectric, ambient operating and storage temperatures are the most significant aging factors, while the operating voltage has a smaller effect. The aging process may be reversed by heating the component above the Curie point. Aging is fastest near the beginning of life of the component, and the device stabilizes over time. Electrolytic capacitors age as the electrolyte evaporates. In contrast with ceramic capacitors, this occurs towards the end of life of the component.
At what point can the aging effect of a capacitor be reversed if the component is heated beyond?
A: the Curie point
Problem: Please answer a question about the following article about Korean War:
On 25 November at the Korean western front, the PVA 13th Army Group attacked and overran the ROK II Corps at the Battle of the Ch'ongch'on River, and then decimated the US 2nd Infantry Division on the UN forces' right flank. The UN Command retreated; the U.S. Eighth Army's retreat (the longest in US Army history) was made possible because of the Turkish Brigade's successful, but very costly, rear-guard delaying action near Kunuri that slowed the PVA attack for two days (2729 November). On 27 November at the Korean eastern front, a U.S. 7th Infantry Division Regimental Combat Team (3,000 soldiers) and the U.S. 1st Marine Division (12,00015,000 marines) were unprepared for the PVA 9th Army Group's three-pronged encirclement tactics at the Battle of Chosin Reservoir, but they managed to escape under Air Force and X Corps support firealbeit with some 15,000 collective casualties.
Whose retreat during the Korean war was the longest in the history of the US Army?
A: U.S. Eighth Army's
Problem: Please answer a question about the following article about Biodiversity:
During the last century, decreases in biodiversity have been increasingly observed. In 2007, German Federal Environment Minister Sigmar Gabriel cited estimates that up to 30% of all species will be extinct by 2050. Of these, about one eighth of known plant species are threatened with extinction. Estimates reach as high as 140,000 species per year (based on Species-area theory). This figure indicates unsustainable ecological practices, because few species emerge each year.[citation needed] Almost all scientists acknowledge that the rate of species loss is greater now than at any time in human history, with extinctions occurring at rates hundreds of times higher than background extinction rates. As of 2012, some studies suggest that 25% of all mammal species could be extinct in 20 years.
What year did Gabriel estimate 30% of of all species will be extinct by?
A: 2050
Problem: Please answer a question about the following article about The Times:
Between 1941 and 1946, the left-wing British historian E.H. Carr was Assistant Editor. Carr was well known for the strongly pro-Soviet tone of his editorials. In December 1944, when fighting broke out in Athens between the Greek Communist ELAS and the British Army, Carr in a Times editorial sided with the Communists, leading Winston Churchill to condemn him and that leader in a speech to the House of Commons. As a result of Carr's editorial, The Times became popularly known during that stage of World War II as the threepenny Daily Worker (the price of the Daily Worker being one penny).
Between 1941 and 1946, which left-wing British historian was Assistant Editor for The Times?
A:
E.H. Carr
