单项选择题

Passage Two
Britain’s government raises millions of pounds each year from the National Lottery (抽奖) and some of this money is used as an additional allowance for the arts. But this money can only be spent on "capital projects", and not on an institution’s day-to-day expenses.
Lottery money has been made available for many exciting new building projects to improve theatres, galleries and museums. But the project which has received the most publicity is the ￡ 78 million renewal on the Royal Opera House in London’s Covent Garden. The House is the home of Britain’s greatest opera company, as well as the Royal Ballet(芭蕾舞团). It’s also considered to be the best arts institutions -- tickets to the opera can cost up to 200 -- and not everyone is happy that so much lottery money is being used for the benefit of a rich minority.
But since builders moved into the Royal Opera House last July, that controversy has been overshadowed by a more serious crisis: the opera company is facing financial collapse.
According to a special investigation, the crisis is the result of serious mismanagement by Opera House staff, and there have been calls for its allowance to be withdrawn completely. Now, the Opera House has to wait to hear from a government working party about its future survival.

Who should be responsible for the opera company’s financial crisis ？（）
