Read the following passage and answer the questions below.
A Stradivarius is one of the violins, cellos, and other stringed instruments built by members of the Stradivari (Stradivarius) family, particularly Antonio Stradivari, during the 17th and 18th centuries. According to their reputation, the quality of their sound has defied attempts to explain or equal it, though this belief is disputed. The name "Stradivarius" has become a superlative often associated with excellence, and the fame of Stradivarius instruments is widespread, appearing in numerous works of fiction.
Depending on condition, instruments made during Stradivari's "golden period" from 1700 to about 1725 can be worth millions of dollars. In 2011, his "Lady Blunt" violin from 1721, which is in pristine condition, was sold at Tarisio auctions for £9.8 million.
These instruments are famous for the quality of sound they produce. However, the many blind tests from 1817 to the present have never found any difference in sound between Stradivari's violins and high-quality violins in comparable style of other makers and periods, nor has acoustic analysis. In a particularly famous test on a BBC Radio programme in 1977, the violinists Isaac Stern and Pinchas Zukerman and the violin expert and dealer Charles Beare tried to distinguish between the "Chaconne" Stradivarius and three other violins, including one made in 1976, played behind a screen by a professional soloist. None of the listeners identified more than two of the four instruments. Two of the listeners identified the 20th-century violin as the Stradivarius.
Are the following statements true, false or not given?
- The superior reputation of Stradivarius instruments has never been questioned.
- The “Lady Blunt” Stradivarius is the most expensive violin every sold.
- Tests have shown that experts are able to distinguish the famous Stradivarius sound.
