Arrange the sentences P, Q, R and S in the correct sequence to form a coherent paragraph.
P: Islam spread south past the Sahara very slowly, especially compared with its sweep across North Africa.
Q: Despite this fact, the traditional beliefs have not completely disappeared.
R: The spread of Islam overshadowed many indigenous (or native) religions, myths, and legends of sub-Saharan Africa.
S: Before the modern era, Africans south of the Sahara had relatively little contact with the rest of the world.

Correct option is C

The correct sequence to form a coherent paragraph is (c) SPRQ.
• S (Before the modern era, Africans south of the Sahara had relatively little contact with the rest of the world.) – Begins by setting the historical context.
• P (Islam spread south past the Sahara very slowly…) – Explains the slow spread of Islam due to the isolation mentioned in S.
• R (The spread of Islam overshadowed many indigenous religions…) – Adds the impact Islam had when it did spread.
• Q (Despite this fact, the traditional beliefs have not completely disappeared.) – Concludes with a contrast and enduring aspect of traditional beliefs.
This order maintains a logical historical flow and contrast between past isolation, cultural transformation, and continuing traditional presence.
