Problem: Please answer a question about the following article about LaserDisc:
LaserDiscs were initially cheaper than videocassettes to manufacture, because they lacked the moving parts and plastic outer shell that are necessary for VHS tapes to work, and the duplication process was much simpler. A VHS cassette has at least 14 parts including the actual tape while LaserDisc has one part with five or six layers. A disc can be stamped out in a matter of seconds whereas duplicating videotape required a complex bulk tape duplication mechanism and was a time-consuming process. However, by the end of the 1980s, average disc-pressing prices were over $5.00 per two-sided disc, due to the large amount of plastic material and the costly glass-mastering process needed to make the metal stamper mechanisms. Due to the larger volume of demand, videocassettes quickly became much cheaper to duplicate, costing as little as $1.00 by the beginning of the 1990s.
Were Laserdiscs initially cheaper or more costly to produce than their VHS counterparts?
A: cheaper
Problem: Please answer a question about the following article about Memory:
Stressful life experiences may be a cause of memory loss as a person ages. Glucocorticoids that are released during stress damage neurons that are located in the hippocampal region of the brain. Therefore, the more stressful situations that someone encounters, the more susceptible they are to memory loss later on. The CA1 neurons found in the hippocampus are destroyed due to glucocorticoids decreasing the release of glucose and the reuptake of glutamate. This high level of extracellular glutamate allow calcium to enter NMDA receptors which in return kills neurons. Stressful life experiences can also cause repression of memories where a person moves an unbearable memory to the unconscious mind. This directly relates to traumatic events in one's past such as kidnappings, being prisoners of war or sexual abuse as a child.
What neurons are damaged during stressful events?
A: The CA1 neurons found in the hippocampus
Problem: Please answer a question about the following article about Gamal Abdel Nasser:
In 1941, Nasser was posted to Khartoum, Sudan, which was part of Egypt at the time. Nasser returned to Sudan in September 1942 after a brief stay in Egypt, then secured a position as an instructor in the Cairo Royal Military Academy in May 1943. In 1942, the British Ambassador Miles Lampson marched into King Farouk's palace and ordered him to dismiss Prime Minister Hussein Sirri Pasha for having pro-Axis sympathies. Nasser saw the incident as a blatant violation of Egyptian sovereignty and wrote, "I am ashamed that our army has not reacted against this attack", and wished for "calamity" to overtake the British. Nasser was accepted into the General Staff College later that year. He began to form a group of young military officers with strong nationalist sentiments who supported some form of revolution. Nasser stayed in touch with the group's members primarily through Amer, who continued to seek out interested officers within the Egyptian Armed Force's various branches and presented Nasser with a complete file on each of them.
Who was Nasser's contact in the armed forces, giving Nasser dossiers?
A: Amer
Problem: Please answer a question about the following article about Grape:
Red wine may offer health benefits more so than white because potentially beneficial compounds are present in grape skin, and only red wine is fermented with skins. The amount of fermentation time a wine spends in contact with grape skins is an important determinant of its resveratrol content. Ordinary non-muscadine red wine contains between 0.2 and 5.8 mg/L, depending on the grape variety, because it is fermented with the skins, allowing the wine to absorb the resveratrol. By contrast, a white wine contains lower phenolic contents because it is fermented after removal of skins.
What type of wine is fermented with grape skin?
A:
red wine
