The passage discusses the challenges TV channels, particularly the BBC, face when transitioning from analogue to digital TV. Key points include:
1. Funding Issues: To finance the switch, the BBC reduced subscriptions to analogue channels and fired program makers.
2. Quality Drop: These actions led to a decline in program quality.
3. Public Alienation: The drop in quality caused fewer people to subscribe to the new digital channels than expected.
4. Financial Crisis: The BBC now faces a severe financial shortfall with little hope of recovery.
5. Resistance to Change: Many channels are hesitant to switch to digital due to these observed pitfalls.
Identifying the Author's Assumption
An assumption is an unstated premise that supports the conclusion. Here, the author implies that switching to digital is problematic because maintaining quality during the transition is difficult, leading to financial failure.
Let's evaluate each option:
(A) It is possible for most channels to switch to digital TV and maintain their public base.
- Analysis: The argument suggests the opposite-that maintaining the public base during the switch is difficult (as seen with the BBC).
- Conclusion: This contradicts the author's implied stance. Not the assumption.
(B) The other channels, like BBC, will fail in successfully switching to digital.
- Analysis: The author uses the BBC's failure as a cautionary tale but doesn't generalize that all channels will fail.
- Conclusion: Too extreme. Not the assumption.
(C) A channel cannot switch successfully if the existing quality of programs isn't maintained.
- Analysis: The BBC's failure is directly tied to its inability to maintain quality during the transition. The author implies that quality maintenance is necessary for a successful switch.
- Conclusion: This aligns perfectly with the argument. Likely the assumption.
(D) BBC can regain its public base and popularity again.
- Analysis: The author states recovery seems "unlikely," so this contradicts the argument.
- Conclusion: Not the assumption.
(E) Digital TV is not a beneficial proposition for most TV channels.
- Analysis: The author acknowledges "many advantages" of digital TV but highlights pitfalls. This option is too absolute.
- Conclusion: Not the assumption.
Why (C) is Correct
The author's reasoning hinges on the idea that the BBC's failure resulted from sacrificing quality during the transition. Thus, the unstated assumption is:
Maintaining program quality is essential for a successful switch to digital TV.
This matches option (C).
