Explanation:

- Let's go through each part of the sentence:

- R: "on the one hand there is the immense beauty" introduces a comparison or contrast.

- P: "of its rain-soaked verdure" continues describing beauty from part R.

- Q: "and on the other there are" sets up a contrast with a different aspect.

- S: "the artifacts of its visible modernity" contrasts with the natural beauty.

- Using this understanding, we can make a coherent sentence:

- R: Start with introducing the beauty.

- P: Follow with what constitutes this beauty.

- Q: Introduce a contrast.

- S: Describe the contrasting element.

- RPQS forms a logical and grammatically correct sentence:

"On the one hand there is the immense beauty of its rain-soaked verdure, and on the other there are the artifacts of its visible modernity."

Hence, RPQS is the correct sequence.
