Final answer:
The student's statement reflects limitations on artistic expression and cultural censorship.
Step-by-step explanation:
The student's statement reflects limitations on artistic expression. When songs with certain words like 'free' are not sung anymore in public, it suggests that there are restrictions on what artists can express through their music. This can occur due to factors such as cultural censorship, where certain themes or messages are deemed inappropriate or sensitive by society or the government. It is important to note that the absence of such songs does not necessarily indicate government control of media or suppression of dissent, as the reason for the limitation on artistic expression can vary.
