Explanation
Correct answer: A.
Choice A is the best answer. In one example, musicians made less money than expected by using the “pay as you wish” model. In the other example, a musician made more money than expected. This suggests that some musicians may have more success than others using the “pay as you wish” model.
Why the other choices are wrong
Choice B
Choice B is incorrect. This inference isn’t supported. In the examples provided, the individual musician was more successful with the “pay as you wish” model than the band was.
Choice C
Choice C is incorrect. This inference isn’t supported. The passage provides no instances in which musicians changed the suggested prices of their songs or albums, nor does it mention this as a possibility.
Choice D
Choice D is incorrect. This inference isn’t supported. The text never discusses the differences in popularity of different musicians, so there is no basis to make this inference.
