Concept:The paragraph describes the logical flow of memory processing: the brain first filters information, then stores it in short-term memory, later moves it to long-term memory, and finally uses repetition for transfer.
Explanation:The opening sentence introduces human memory as complex.
Sentence R comes first because it explains how the brain filters and encodes information efficiently.
Sentence P follows next, describing short-term memory as temporary storage for immediate use.
Sentence S then talks about long-term memory, which holds information for a long period.
Sentence Q comes last, stating that repetition transfers information to long-term memory.
The correct order is R, P, S, Q.
This gives a clear sequence: encode, short-term store, long-term store, transfer via repetition.
Answer:Option C (RPSQ)
