单项选择题

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crisis is the result of serious mismanagement by Opera House staff, and there have been calls for its allowance to be withdrawn completely.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.

The statement "that controversy ... financial collapse" (Par3, sentence 1) can be best paraphrased as ().

A. that controversy has become less important because of the opera company’s financial crisis
B. that controversy has become more serious because of the opera company’s financial crisis
C. that controversy has become more important than the opera company’s financial crisis
D. that controversy has been caused by the opera company’s financial crisis.
