Rearrange the following sentences to form a coherent paragraph:
1. This is why it is widely used for tasks such as spam detection, speech recognition, and disease prediction.
2. Data science involves extracting useful insights from data using statistical methods and computational tools.
3. By examining large datasets, it uncovers hidden trends and supports better decision-making.
4. Rather than relying on guesses, analysts work with evidence drawn from real-world data.

The correct option is 2, 4, 3, 1.

To form a coherent and logical paragraph, let's analyze the sequence and connection between the sentences step-by-step:

1. Identify the introductory topic sentence (Sentence 2):
Sentence 2, "Data science involves extracting useful insights from data using statistical methods and computational tools," introduces the core topic—Data Science—and provides its general definition. This serves as the ideal opening statement for the paragraph.

2. Establish logical continuation (Sentence 4):
Sentence 4, "Rather than relying on guesses, analysts work with evidence drawn from real-world data," elaborates directly on how insights are extracted, contrasting real-world data evidence against mere guesswork.

3. Explain the outcome/benefit (Sentence 3):
Sentence 3, "By examining large datasets, it uncovers hidden trends and supports better decision-making," explains what analyzing this evidence achieves—uncovering trends and helping make informed decisions.

4. State the conclusion/applications (Sentence 1):
Sentence 1, "This is why it is widely used for tasks such as spam detection, speech recognition, and disease prediction," starts with "This is why...", which provides a concluding cause-and-effect statement linking all the previously mentioned benefits to real-world applications.

Therefore, the logical sequence of the sentences is 2 → 4 → 3 → 1.
