根据以下材料，回答31-35题<br /> The review of the BBC charter that was launched recently with the culture secretary John Whittingdale's policy proposal represents a more profound challenge than any that the corporation has faced before.It is accustomed to living in a bracing environment requiring constant vigilance in defense of its governing purpose of providing universal public value.Its Reithian ideal, to be guide, philosopher and friend to its audience,not impervious to the market but with responsibilities beyond it, unavoidably sets it at odds with commercial rivals.<br /> Yet the challenge now goes well beyond the long-running campaign of business interests like the Murdoch empire's.The political climate is hostile.The tide of free market politics is running swiftly.Mr.Whittingdale, who chaired the Commons culture committee for 10 years and knows the BBC intimately, has a long public record of questioning its funding, its reach and the meaning of its remit of universality.The wider Conservative government is committed to the notion of a smaller state.<br /> The greatest challenge, however, is the way digital technology has simultaneously expanded the scope of the competition and narrowed the field on which it is fought.So, while there is almost no limit to the amount of content that can be conveyed digitally, there is a narrowing focus on how it is consumed.The future is mobile.Indifferent but accelerating ways, the digital revolution is undermining the business model of newspapers and commercial broadcasting.The BBC, with its significant online presence, is now seen by a greater number of competitors as a more existential menace—in a political climate that has never been chillier.<br /> The impression of a hanging jury is strengthened by a panel of experts, most of whom have a close connection with the BBC's critics in TV and newspapers.They are to help Mr.Whittingdale interrogate the corporation's underpinnings from a rigorously skeptical position.Universality, for example, could be redefined so that it is understood not to mean providing content that all TV license payers enjoy some of the time on every platform in use, but only those things the market cannot be relied upon to offer—news,natural history and drama seem to be the minimalist offer.Similarly, the obligation to be distinctive also faces reinterpretation.Revising more narrowly the way that "universal" and "distinctive" are understood is likely to mean fewer TV and radio channels and less digital content.That in turn means, the policy proposal suggests, a smaller BBC and a lower license fee.That is not impossible, but it would mean a different BBC.<br /> The BBC is not perfect.But set against its role as a thread in the warp and woof of national life, its flaws seem insignificant.Its funding model and its mission to inform, educate and entertain allow it to reflect the different parts of the UK to each other and to the world.That is why Britain tops the global soft power league.There could be a different BBC.But it would reflect a different Britain.<br /> What makes BBC to be regarded as a threat to its competitors?
