In the following question, the first and the last parts of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts - P, Q, R, and S. These four parts are not given in their proper order. Read the sentence/passage and find the most logical order of the parts between 1 and 6.
1. Human memory is a complex neurological process.
P: Short-term memory stores data temporarily for immediate use.
Q: Information can be transferred to long-term memory with repetition.
R: The brain filters and encodes information efficiently.
S: Long-term memory holds information for an extended period.
6. Understanding memory helps improve learning strategies.

Correct option is C

Option (c) RPSQ is the correct order of the given sentences.
· R logically follows the opener by explaining the mechanism ( filters and encodes) of the “complex neurological process.”
· P then introduces the first type of memory— short-term—which naturally comes before long-term when describing stages.
· S complements P by presenting the second type, long-term memory, creating a clear short-term → long-term progression.
· Q fits after S because it explicitly refers to transfer to long-term memory (already introduced in S) and adds the condition “with repetition.”
· The concluding line 6 sums up the practical takeaway (learning strategies), so R→P→S→Q provides a coherent flow from mechanism → types → process of transfer → application.
