Here is a question about this article: Over time, fidelity, dynamic and noise levels improved to the point that it was harder to tell the difference between a live performance in the studio and the recorded version. This was especially true after the invention of the variable reluctance magnetic pickup cartridge by General Electric in the 1940s when high quality cuts were played on well-designed audio systems. The Capehart radio/phonographs of the era with large diameter electrodynamic loudspeakers, though not ideal, demonstrated this quite well with "home recordings" readily available in the music stores for the public to buy.
What is the answer to this question: In what era could you find good quality recordings and playbacks at home?

So... 1940s


Here is a question about this article: The Royal Collection, which includes thousands of historic works of art and the Crown Jewels, is not owned by the Queen personally but is held in trust, as are her official residences, such as Buckingham Palace and Windsor Castle, and the Duchy of Lancaster, a property portfolio valued in 2014 at £442 million. Sandringham House and Balmoral Castle are privately owned by the Queen. The British Crown Estate – with holdings of £9.4 billion in 2014 – is held in trust by the sovereign and cannot be sold or owned by Elizabeth in a private capacity.
What is the answer to this question: How much is the worth of the British Crown Estate?

So... £9.4 billion


Here is a question about this article: Traditional sports include Swiss wrestling or "Schwingen". It is an old tradition from the rural central cantons and considered the national sport by some. Hornussen is another indigenous Swiss sport, which is like a cross between baseball and golf. Steinstossen is the Swiss variant of stone put, a competition in throwing a heavy stone. Practiced only among the alpine population since prehistoric times, it is recorded to have taken place in Basel in the 13th century. It is also central to the Unspunnenfest, first held in 1805, with its symbol the 83.5 kg stone named Unspunnenstein.
What is the answer to this question: What was the name of the 83.5 kg stone that symbolized the Unspunnenfest, first held in 1805?
