Article: Last but not least the electric double-layer capacitor (now Supercapacitors) were invented. In 1957 H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors. Because the double layer mechanism was not known by him at the time, he wrote in the patent: "It is not known exactly what is taking place in the component if it is used for energy storage, but it leads to an extremely high capacity.".

Question: Who invented low voltage electrolytic capacitors with porous carbon electrodes?
Ans: H. Becker

Article: Hunting-gathering was the common human mode of subsistence throughout the Paleolithic, but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples.

Question: What type of conditions are not present in modern societies?
Ans: pristine

Article: The music of the indigenous peoples of Central Mexico and Central America was often pentatonic. Before the arrival of the Spaniards and other Europeans, music was inseparable from religious festivities and included a large variety of percussion and wind instruments such as drums, flutes, sea snail shells (used as a trumpet) and "rain" tubes. No remnants of pre-Columbian stringed instruments were found until archaeologists discovered a jar in Guatemala, attributed to the Maya of the Late Classic Era (600900 CE), which depicts a stringed musical instrument which has since been reproduced. This instrument is one of the very few stringed instruments known in the Americas prior to the introduction of European musical instruments; when played it produces a sound virtually identical to a jaguar's growl.

Question: Where did archaeologists find a depiction of a Mayan stringed instrument?
Ans: a jar in Guatemala

Article: Up to 600 pro-Tibet protesters were expected to attend the relay, along with between 2,000 and 10,000 Chinese supporters. Taking note of the high number of Chinese supporters, Ted Quinlan, head of the Canberra torch relay committee, said: "We didn't expect this reaction from the Chinese community. It is obviously a well-coordinated plan to take the day by weight of numbers. But we have assurances that it will be done peacefully.". Also, Australia's ACT Chief Minister, Jon Stanhope confirmed that the Chinese embassy was closely involve to ensure that "pro-China demonstrators vastly outnumbered Tibetan activists." Australian freestyle swimmer and five-time Olympic gold medalist Ian Thorpe ended the Australian leg of the torch relay April 24, 2008, touching the flame to light a cauldron after a run that was only marginally marked by protests. People demonstrated both for China and for Tibet. At least five people were arrested during the torch relay. Police said "the five were arrested for interfering with the event under special powers enacted in the wake of massive protests against Chinese policy toward Tibet." At one point, groups of Chinese students surrounded and intimidated pro-Tibet protesters. One person had to be pulled aboard a police launch when a group of pro-Chinese students looked like they might force him into the lake.

Question: Who did not expect that reaction from the Chinese community?
Ans:
Ted Quinlan
