Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. changed.

Meaning of the words:
Changed: Made or become different.
Freed: Released from captivity or restriction.
Startled: Caused to feel sudden shock or alarm.
Unconcerned: Not worried or interested.
Correct word: Changed
Reason: Only the word 'changed' fits logically and grammatically. The sentence aims to express that classrooms have undergone very little transformation over the past century. 'Changed very little' is a common collocation that accurately conveys this meaning.
