Final answer:
The question is an (A) assumption made, but the answer is subjective and can vary depending on one's perspective.
Step-by-step explanation:
The statement is an assumption made. The question assumes that Chilean students were right in 2012 to stage protests demanding free university education because they cannot afford to pay fees.
However, the answer to whether the students were right or not is subjective and can vary depending on one's perspective. Some arguments in favor of free university education include increasing access to education and reducing socioeconomic inequality, while arguments against it include the potential strain on government resources and the importance of personal responsibility in financing education.
