Final answer:
The correct answer is option D. Cannot be determined.
Step-by-step explanation:
The question is whether Chilean students were right to stage protests in 2012 demanding free university education in Chile. To determine if this assumption is valid, we can look at examples from other countries. It is true that some countries, like Finland, offer free education, including university education, to all citizens.
However, whether this assumption is valid for Chile specifically cannot be determined as it depends on various factors such as the country's economic situation, government policies, and educational priorities.
