input question: Given the following context:  John Winston Ono Lennon  (9 October 1940 – 8 December 1980) was an English singer, songwriter and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group achieved worldwide fame during the 1960s. In 1969, Lennon started the Plastic Ono Band with his second wife, Yoko Ono, and he continued to pursue a solo career following the Beatles' break-up in April 1970. Born  John Winston Lennon in Liverpool, he became involved in the skiffle craze as a teenager. In 1957, he formed his first band, the Quarrymen, which evolved into the Beatles in 1960. Further to his Plastic Ono Band singles such as "Give Peace a Chance" and "Instant Karma!", Lennon subsequently produced albums that included John Lennon/Plastic Ono Band and Imagine, and songs such as  "Working Class Hero", "Imagine" and "Happy Xmas (War Is Over)". After moving to New York City in 1971, he never returned to England again. In 1975, he disengaged himself from the music business to raise his infant son Sean, but re-emerged with Ono in 1980 with the album Double Fantasy.

Lennon revealed a rebellious nature and acerbic wit in his music, writing, drawings, on film and in interviews. He was controversial through his political and peace activism. From 1971 onwards, his criticism of the Vietnam War resulted in a three-year attempt by the Nixon administration to deport him.

He had 25 number-one singles on the US Billboard Hot 100 chart as a writer, co-writer or performer.

Given the following context:  The Symphony No. 8 in E-flat major by Gustav Mahler is one of the largest-scale choral works in the classical concert repertoire. Because it requires huge instrumental and vocal forces it is frequently called the "Symphony of a Thousand", although the work is normally presented with far fewer than a thousand performers and the composer did not sanction that name. The work was composed in a single inspired burst, at Maiernigg in southern Austria in the summer of 1906. The last of Mahler's works that was premiered in his lifetime, the symphony was a critical and popular success when he conducted the Munich Philharmonic in its first performance, in Munich, on 12 September 1910. The fusion of song and symphony had been a characteristic of Mahler's early works. In his "middle" compositional period after 1901, a change of direction led him to produce three purely instrumental symphonies. The Eighth, marking the end of the middle period, returns to a combination of orchestra and voice in a symphonic context. The structure of the work is unconventional; instead of the normal framework of several movements, the piece is in two parts. Part I is based on the Latin text of a 9th-century Christian hymn for Pentecost, Veni creator spiritus ("Come, Creator Spirit"), and Part II is a setting of the words from the closing scene of Goethe's Faust. The two parts are unified by a common idea, that of redemption through the power of love, a unity conveyed through shared musical themes. Mahler had been convinced from the start of the work's significance; in renouncing the pessimism that had marked much of his music, he offered the Eighth as an expression of confidence in the eternal human spirit. In the period following the composer's death, performances were comparatively rare. However, from the mid-20th century onwards the symphony has been heard regularly in concert halls all over the world, and has been recorded many times. While recognising its wide popularity, modern critics have divided opinions on the work; Theodor W....  answer the following question:  What is the last name of the person who conducted the Munich Philharmonic in Munich on September 12, 1910?

Problem: Given the question: Given the following context:  For years, stories circulated of a treasure being buried within the amphitheater. W. T. McWhorter was determined to find out if it was true, so he planned to dynamite the amphitheater on the day he was to transfer the deed to the CoE. Spectators attended the planned explosion, but it was stopped just in time by CoE attorney David Waid.The dam was completed, and Beaver Lake was at full height by June 1966. For all intents and purposes, Harvey's Monte Ne was gone. However, in times of drought, some of the structures become visible again. The lake dropped to its lowest level on January 22, 1977, more than 27 feet (8 m) below its average depth, and the amphitheater and bridges were visible for the first time in more than 10 years. Before the water flooded downtown Monte Ne again, the rest of the buildings were either bulldozed or moved to avoid problems for swimmers, boaters, and fishermen. The few bridges that spanned the lagoon and the amphitheater were not demolished.In 2006, the waters of Beaver Lake once again receded to their lowest level since 1984, just above 1,100 feet (335 m). This generated a new brief interest in Monte Ne and people were once again attracted to the edge of the lake to explore the remains. The upper part of the amphitheater and the retaining wall built for the never constructed pyramid were exposed for a time before being once again swallowed by the lake.The flooded Monte Ne has become a site of interest for scuba divers who dive by the amphitheater to get a look at the submerged structure. The water is moderately clear and temperatures comfortable.  answer the following question:  What is the name of the lake that dropped to its lowest level on January 22, 1977?
