Article: The lateral cut NAB curve was remarkably similar to the NBC Orthacoustic curve that evolved from practices within the National Broadcasting Company since the mid-1930s. Empirically, and not by any formula, it was learned that the bass end of the audio spectrum below 100 Hz could be boosted somewhat to override system hum and turntable rumble noises. Likewise at the treble end beginning at 1,000 Hz, if audio frequencies were boosted by 16 dB at 10,000 Hz the delicate sibilant sounds of speech and high overtones of musical instruments could survive the noise level of cellulose acetate, lacquer/aluminum, and vinyl disc media. When the record was played back using a complementary inverse curve, signal-to-noise ratio was improved and the programming sounded more lifelike.

Question: How did the NBC Othacoustic curve relate to the NAB curve?
Ans: remarkably similar

Here is a question about this article: The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption is incorrect, as once solidified, glass stops flowing. The reason for the observation is that in the past, when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the crown glass process, described above). This plate was then cut to fit a window. The pieces were not absolutely flat; the edges of the disk became a different thickness as the glass spun. When installed in a window frame, the glass would be placed with the thicker side down both for the sake of stability and to prevent water accumulating in the lead cames at the bottom of the window. Occasionally such glass has been found installed with the thicker side at the top, left or right.
What is the answer to this question: What was the benefit of installing glass with the thick side at the bottom, in addition to avoiding water accumulation?
****
So... stability

****
The answer: moth

Problem: Please answer a question about the following article about Antarctica:
Since the 1970s, an important focus of study has been the ozone layer in the atmosphere above Antarctica. In 1985, three British scientists working on data they had gathered at Halley Station on the Brunt Ice Shelf discovered the existence of a hole in this layer. It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons (CFCs) emitted by human products. With the ban of CFCs in the Montreal Protocol of 1989, climate projections indicate that the ozone layer will return to 1980 levels between 2050 and 2070.
Where in Antarctica is Halley Station?
A: Brunt Ice Shelf

Egypt has a wide range of beaches situated on the Mediterranean and the Red Sea that extend to over 3,000 km. The Red Sea has serene waters, coloured coral reefs, rare fish and beautiful mountains. The Akba Gulf beaches also provide facilities for practising sea sports. Safaga tops the Red Sea zone with its beautiful location on the Suez Gulf. Last but not least, Sharm el-Sheikh (or City of Peace), Hurghada, Luxor (known as world's greatest open-air museum/ or City of the of world monuments), Dahab, Ras Sidr, Marsa Alam, Safaga and the northern coast of the Mediterranean are major tourist's destinations of the recreational tourism.

What locations on Egypt's northern coast are major tourist destinations for recreational tourism?
Answer: Dahab, Ras Sidr, Marsa Alam, Safaga

The tourism industry began in the early 19th century when foreigners visited the Alps, traveled to the bases of the mountains to enjoy the scenery, and stayed at the spa-resorts. Large hotels were built during the Belle Epoque; cog-railways, built early in the 20th century, brought tourists to ever higher elevations, with the Jungfraubahn terminating at the Jungfraujoch, well above the eternal snow-line, after going through a tunnel in Eiger. During this period winter sports were slowly introduced: in 1882 the first figure skating championship was held in St. Moritz, and downhill skiing became a popular sport with English visitors early in the 20th century, as the first ski-lift was installed in 1908 above Grindelwald.
When were large hotels built in the Alps?
during the Belle Epoque
