Question

Four sentences that are a part of paragraph are given below; the sentences may or may not be in the right order; create the sequence that forms a coherent paragraph.
1. Look forward a few decades to an invention which can end the energy crisis, change the global economy and curb climate change at a stroke: commercial fusion power.
2. To gain meaningful insights, logic has to be accompanied by asking probing questions of nature through controlled tests, precise observations and clever analysis.
3. The greatest of all inventions is the über-invention that has provided the insights on which others depend: the modern scientific method.
4. This invention is inconceivable without the scientific method; it will rest on the application of a diverse range of scientific insights, such as the process transforming hydrogen into helium to release huge amounts of energy.

• A. 1234
• B. 3214
• C. 4312
• D. 1243

Answer 1

The Correct Option is B

The task is to arrange the given sentences in a logical order to form a coherent paragraph. Below is the analysis of each sentence's role:

Sentence Breakdown: 

1. Sentence 1: This introduces the idea of a groundbreaking invention, commercial fusion power, that has the potential to solve major global issues like energy crisis, economic change, and climate change.
2. Sentence 2: It explains the importance of logic, tests, observations, and analysis to obtain meaningful insights, directly linking to the concept of the scientific method.
3. Sentence 3: This sentence states that the scientific method is the greatest invention that has enabled all others, including fusion power.
4. Sentence 4: This emphasizes that fusion power relies on the application of scientific principles, such as hydrogen transforming into helium to release energy, which is possible due to the scientific method.

Correct Sequence of Sentences:

To create a coherent paragraph, the sentences should be ordered as follows:

1. Sentence 3: Start by recognizing the scientific method as the greatest invention that forms the foundation for others.
2. Sentence 2: Explain how logic and controlled tests, which are part of the scientific method, are essential for gaining meaningful insights.
3. Sentence 1: Introduce the concept of commercial fusion power as the invention that can address global challenges.
4. Sentence 4: Conclude by showing that fusion power depends on the scientific method and various scientific insights.

Conclusion:

The correct order for the sentences is: 3 → 2 → 1 → 4. Therefore, the correct answer is (B).
