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 objective is to arrange the provided sentences into a logical sequence, forming a cohesive paragraph. The role of each sentence is analyzed below:

Sentence Breakdown:

1. Sentence 1: Introduces commercial fusion power as a transformative invention capable of resolving significant global issues like energy shortages, economic shifts, and climate change.
2. Sentence 2: Highlights the critical role of logic, empirical testing, observation, and analytical processes in deriving valuable understanding, directly correlating with the scientific method.
3. Sentence 3: Identifies the scientific method as the paramount invention, serving as the bedrock for all subsequent innovations, including fusion power.
4. Sentence 4: Emphasizes that the development of fusion power is contingent on applying scientific principles, such as the energy-releasing conversion of hydrogen to helium, a feat made possible by the scientific method.

Correct Sequence of Sentences:

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

1. Sentence 3: Begin by establishing the scientific method as the primary invention underpinning all others.
2. Sentence 2: Elaborate on how logical reasoning and controlled experimentation, integral components of the scientific method, are indispensable for acquiring meaningful insights.
3. Sentence 1: Present commercial fusion power as the invention poised to address global challenges.
4. Sentence 4: Conclude by illustrating the dependence of fusion power on the scientific method and derived scientific knowledge.

Conclusion:

The optimal sentence order is: 3 → 2 → 1 → 4. Consequently, the correct answer is (B).
