Problem: Please answer a question about the following article about LaserDisc:
At least where the digital audio tracks were concerned, the sound quality was unsurpassed at the time compared to consumer videotape, but the quality of the analog soundtracks varied greatly depending on the disc and, sometimes, the player. Many early and lower-end LD players had poor analog audio components, and many early discs had poorly mastered analog audio tracks, making digital soundtracks in any form most desirable to serious enthusiasts. Early DiscoVision and LaserDisc titles lacked the digital audio option, but many of those movies received digital sound in later re-issues by Universal, and the quality of analog audio tracks generally got far better as time went on. Many discs that had originally carried old analog stereo tracks received new Dolby Stereo and Dolby Surround tracks instead, often in addition to digital tracks, helping boost sound quality. Later analog discs also applied CX Noise Reduction, which improved the signal-noise ratio of their audio.
What result did adding CX Noise Reduction have on analog discs?
A: improved the signal-noise ratio of their audio
Problem: Please answer a question about the following article about Dell:
By the late 2000s, Dell's "configure to order" approach of manufacturing—delivering 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 Łodź in Poland.
What decade did Dell's manufacturing process become less efficient?
A: 2000s
Problem: Please answer a question about the following article about Modern history:
In the latter part of the second revolution, Thomas Alva Edison developed many devices that greatly influenced life around the world and is often credited with the creation of the first industrial research laboratory. In 1882, Edison switched on the world's first large-scale electrical supply network that provided 110 volts direct current to fifty-nine customers in lower Manhattan. Also toward the end of the second industrial revolution, Nikola Tesla made many contributions in the field of electricity and magnetism in the late 19th and early 20th centuries.
Where was Thomas Edison's electrical supply network located?
A: lower Manhattan
Problem: Please answer a question about the following article about Botany:
Plant physiology encompasses all the internal chemical and physical activities of plants associated with life. Chemicals obtained from the air, soil and water form the basis of all plant metabolism. The energy of sunlight, captured by oxygenic photosynthesis and released by cellular respiration, is the basis of almost all life. Photoautotrophs, including all green plants, algae and cyanobacteria gather energy directly from sunlight by photosynthesis. Heterotrophs including all animals, all fungi, all completely parasitic plants, and non-photosynthetic bacteria take in organic molecules produced by photoautotrophs and respire them or use them in the construction of cells and tissues. Respiration is the oxidation of carbon compounds by breaking them down into simpler structures to release the energy they contain, essentially the opposite of photosynthesis.
How do animals use plants?
A:
in the construction of cells and tissues
