Directions: In this section, each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the answer sheet.

S1: Machine Learning models have become integral to predictive analytics in various sectors.

S6: The process helps in refining the accuracy of predictions over time with real-world usage.

P: This cycle of feedback is crucial for model improvement.

Q: They are initially trained with historical data to make predictions.

R: Continuous learning mechanisms are then applied to these models.

S: After deployment, they gather new data, which is incorporated back into the model.
