Select the most appropriate option to fill in blank 4.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. encroachment.
The passage talks about modern societies and environmental degradation affecting primitive cultures.
"Encroachment" means gradual invasion or intrusion, which suits the context as modern societies are taking over traditional lands.
Other options:
Migration: Moving from one place to another, which doesn’t convey intrusion.
Possession: Owning something, which is incorrect here.
Estimation: An approximate calculation, which doesn’t fit.
Hence, the chosen option is correct
