Rearrange the following sentences to form a coherent paragraph:

1. It is a process that involves the systematic and objective investigation of a subject to discover new facts or to confirm existing ones.

2. Research is a foundational pillar of academic and scientific progress.

3. This can be either theoretical, aiming to expand knowledge, or applied, seeking to solve a practical problem.

4. The findings of this investigation are then documented and peer-reviewed to ensure validity and credibility.

• A. 2, 1, 3, 4
• B. 1,2,4,3
• C. 4, 3, 2, 1
• D. 3, 4, 1, 2

Answer 1

Answer:

A. 2, 1, 3, 4

(2) Research is a foundational pillar of academic and scientific progress. (1) It is a process that involves the systematic and objective investigation of a subject to discover new facts or to confirm existing ones. (3) This can be either theoretical, aiming to expand knowledge, or applied, seeking to solve a practical problem. (4) The findings of this investigation are then documented and peer-reviewed to ensure validity and credibility.

To solve sentence rearrangement (jumbled sentences) logically, we must look for structural links, pronouns, and the flow of ideas:

• Finding the Opening Sentence (Sentence 2):

  Sentence 2 introduces the central theme of the paragraph—"Research"—and defines its broad importance. An opening sentence is typically independent and introduces a new concept without relying on pronouns that refer to previous statements.

• Establishing the First Link (Sentence 2 $\rightarrow$ Sentence 1):

  Sentence 1 begins with the pronoun "It" ("It is a process..."). This pronoun directly refers back to the singular noun "Research" introduced in Sentence 2. Furthermore, Sentence 1 elaborates on the definition of research by calling it an "investigation".

• Establishing the Second Link (Sentence 1 $\rightarrow$ Sentence 3):

  Sentence 3 begins with the demonstrative pronoun "This" ("This can be either theoretical..."). "This" refers back to the "process" or the nature of research described in Sentence 1. It logically categorizes the process into two types: theoretical or applied.

• Finding the Concluding Sentence (Sentence 4):

  Sentence 4 talks about "The findings of this investigation...". The phrase "this investigation" directly links back to the word "investigation" first mentioned in Sentence 1. Documenting and peer-reviewing findings naturally represent the final, concluding steps of any research process.
