The sentences given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the numbers as your answer.

  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 uber-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.

Solution

✅ Correct Answer: 3214

Let us trace the connections between ideas.

Step 1: Find the starting point -> Sentence 3 introduces a broad concept (scientific method as greatest invention)

Step 2: Look for explanations -> Sentence 2 explains how the scientific method works

Step 3: Find examples -> Sentence 1 gives a specific future invention (fusion power)

Step 4: Look for connections -> Sentence 4 links the example back to the main concept


From passage: "The greatest of all inventions is the uber-invention" (sentence 3) and "This invention is inconceivable without the scientific method" (sentence 4)

Thought Process:

Start broad -> explain details -> give example -> connect back

3 (introduces scientific method) -> 2 (explains how it works) -> 1 (gives fusion power example) -> 4 (connects fusion back to scientific method)

The word "this invention" in sentence 4 must refer to something mentioned just before -> that's "commercial fusion power" from sentence 1.


Since this question only has one correct answer and no wrong options to eliminate, the sequence is:

🟢 3214 -> Creates perfect logical flow from general concept to specific example and back to connection

The paragraph flows: Scientific method is greatest invention -> Here's how it works -> Here's a future example -> That example depends on scientific method
