Select the most appropriate option to fill in blank 1.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. structures.
The passage describes primitive cultures lacking complex social systems.
"Structures" refers to organized systems, that fits best.
Other options:
Borders: Refers to boundaries, which is irrelevant here.
Outlines: Refers to summaries, which doesn’t fit.
Configurations: Refers to arrangements of parts, but "structures" is the more appropriate term for social systems.
Hence, the chosen option is correct.
