Rearrange the following sentences to form a coherent paragraph: 1. This is especially useful in software development, where multiple programmers can work on the same codebase simultaneously without conflict.2. Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later.3. The process involves a specific set of tools and commands that allow for the manipulation and tracking of changes.4. By using version control, a project can maintain a complete history of its development, allowing for easy rollback and collaboration.

Correct — A. Start with the sentence that needs nothing before it, then follow the reference words.

2 opens: it defines version control.
4 gives the payoff of using it: a complete history and easy rollback.
3 begins "The process", the process of using version control that 4 just described.
1 begins "This" and names where it matters most: software development, many programmers at once.

2, 4, 3, 1 → option (a)

Why the others are wrong

• (b)
  2, 3, 4, 1 — Puts "The process" before the use it describes. The key reads 3's "The process" as using version control, which 4 introduces and whose tools and commands 3 then lists. 2, 3, 4, 1 puts 3 ahead of 4.
• (c)
  3, 2, 4, 1 — "The process" cannot open the paragraph. "The" points back to a process already mentioned, and at the start nothing has been. Version control is not even defined until 2.
• (d)
  4, 1, 2, 3 — Uses version control before defining it. 4 opens "By using version control" and 1 praises it before 2 says what it is. The definition has to come first.

Sentence rearrangement is decided by the links between sentences, not by topic.

The opener introduces its subject in full: "Version control is a system that…"
Reference words need something before them: "The process", "This".
An expanded idea follows the idea it expands: "recall specific versions later" in 2 grows into "a complete history" and "easy rollback" in 4.

Fix the opener first, then place each reference word straight after what it points to.

Key facts

• "The" + noun, as in "The process", points back to something already mentioned, so it cannot open a paragraph.
• A sentence starting "This" needs an earlier idea to refer to.
• A sentence that defines the topic in full is the natural opener. One that uses the term undefined comes later.

Common traps

• Pairing sentences by shared topic words, like collaboration and programmers, instead of by what the reference words point to.
• Opening with a sentence that starts "The process" or "This".
