Question: There is some controversy surrounding the effect of dietary fat on the development of cardiovascular disease. People are often advised to keep a diet where less than 30% of the energy intake derives from fat, a diet that contains less than 7% of the energy intake in the form of saturated fat, and a diet that contains less than 300 mg/day of cholesterol. Replacing saturated with mono- polyunsaturated fat is also recommended, as the consumption of polyunsaturated fat instead of saturated fat may decrease coronary heart disease. Olive oil, rapeseed oil and related products are to be used instead of saturated fat.
Is there an answer to this question: What controversy have dieticians largely settled?

Answer: unanswerable

Question: The highest temperature recorded within city limits was 104 F (40 C), on June 2, 1985, and June 24, 1944, and the lowest was 7 F (14 C) on February 14, 1899, although at the airport, where official records are kept, the historical range is 105 F (41 C) on August 1, 1999 down to 6 F (14 C) on January 21, 1985. Hurricanes are a major threat to the area during the summer and early fall, with several severe hurricanes hitting the area most notably Hurricane Hugo on September 21, 1989 (a category 4 storm). Dewpoint in the summer ranges from 67.8 to 71.4 F (20 to 22 C).
Is there an answer to this question: What was the lowest temperature ever recorded Charleston's city limit?

Answer: 7 F (14 C)

Question: Time appears to have a directionthe past lies behind, fixed and immutable, while the future lies ahead and is not necessarily fixed. Yet for the most part the laws of physics do not specify an arrow of time, and allow any process to proceed both forward and in reverse. This is generally a consequence of time being modeled by a parameter in the system being analyzed, where there is no "proper time": the direction of the arrow of time is sometimes arbitrary. Examples of this include the Second law of thermodynamics, which states that entropy must increase over time (see Entropy); the cosmological arrow of time, which points away from the Big Bang, CPT symmetry, and the radiative arrow of time, caused by light only traveling forwards in time (see light cone). In particle physics, the violation of CP symmetry implies that there should be a small counterbalancing time asymmetry to preserve CPT symmetry as stated above. The standard description of measurement in quantum mechanics is also time asymmetric (see Measurement in quantum mechanics).
Is there an answer to this question: In what directions do the laws of entropy allow light to go?

Answer: unanswerable

Question: In 2012, news was released about a new farming site discovered in Munam-ri, Goseong, Gangwon Province, South Korea, which may be the earliest farmland known to date in east Asia. "No remains of an agricultural field from the Neolithic period have been found in any East Asian country before, the institute said, adding that the discovery reveals that the history of agricultural cultivation at least began during the period on the Korean Peninsula". The farm was dated between 3600 and 3000 B.C. Pottery, stone projectile points, and possible houses were also found. "In 2002, researchers discovered prehistoric earthenware, jade earrings, among other items in the area". The research team will perform accelerator mass spectrometry (AMS) dating to retrieve a more precise date for the site.
Is there an answer to this question: What items were found on the Korean farm site?

Answer:
Pottery, stone projectile points, and possible houses
