Problem: The second decline was not as complete as the first. Thousands of people had learned to play the instrument. Even as the second wave of mandolin popularity declined in the early 20th century, new versions of the mandolin began to be used in new forms of music. Luthiers created the resonator mandolin, the flatback mandolin, the carved-top or arched-top mandolin, the mandolin-banjo and the electric mandolin. Musicians began playing it in Celtic, Bluegrass, Jazz and Rock-n-Roll styles — and Classical too.
 Why was the second rise in popularity not a strong as the first?

Problem: It is often said that Russia was militarily weak, technologically backward, and administratively incompetent. Despite its grand ambitions toward the south, it had not built its railroad network in that direction, and communications were poor. The bureaucracy was riddled with graft, corruption and inefficiency and was unprepared for war. Its navy was weak and technologically backward; its army, although very large, was good only for parades, suffered from colonels who pocketed their men's pay, poor morale, and was out of touch with the latest technology developed by Britain and France. By the war's end, everyone realized the profound weaknesses of the Russian military, and the Russian leadership was determined to reform it.
What did Russia fail to build south?
---
Answer: railroad network


Problem: At this point, Fox whispered that there was "no loss of friendship". "I regret to say there is", Burke replied, "I have indeed made a great sacrifice; I have done my duty though I have lost my friend. There is something in the detested French constitution that envenoms every thing it touches". This provoked a reply from Fox, yet he was unable to give his speech for some time since he was overcome with tears and emotion, he appealed to Burke to remember their inalienable friendship, but also repeated his criticisms of Burke and uttered "unusually bitter sarcasms". This only aggravated the rupture between the two men. Burke demonstrated his separation from the party on 5 June 1791 by writing to Fitzwilliam, declining money from him.
When did Burke leave the party?
