Rearrange the following sentences in correct order to make a logical passage. 1. This allows for greater efficiency and collaboration. 2. Cloud computing has revolutionized data storage and access. 3. It eliminates the need for extensive on-premise infrastructure. 4. Businesses worldwide are rapidly adopting this technology.

Correct — D. Sentence 2 names the topic, cloud computing, so it opens.

It eliminates (3) needs its noun just before it, and cloud computing in 2 is that noun.
This allows (1) sums up 3: dropping extensive on-premise infrastructure is what allows greater efficiency.
This technology (4) widens out to businesses worldwide adopting it, and closes.

2-3-1-4 → option (d).

Why the others are wrong

• (a)
  2-1-3-4 — 2-1-3-4 puts sentence 1, whose subject is 'This', between cloud computing (2) and 'It eliminates' (3). The pronoun It is left with no clear noun to point back to.
• (b)
  2-4-1-3 — 2-4-1-3 reaches adoption before any benefit is stated, then ends on 'It eliminates', with It three sentences away from cloud computing.
• (c)
  3-4-2-1 — 3-4-2-1 opens on It, a pronoun with nothing before it to stand for. The subject has to be named before a pronoun can refer to it.

When a jumbled set carries It, This and this technology, the pronouns build the order. Find the sentence that names the subject, here 2, and open with it.

Then place each pronoun right after what it stands for: It after cloud computing, This after the idea it sums up.

Key facts

• Sentence 2 is the only one that names cloud computing, so it opens.
• It in sentence 3 must sit next to the noun it replaces, cloud computing in sentence 2.
• This in sentence 1 sums up a whole idea: removing the need for extensive on-premise infrastructure.

Common traps

• Putting This allows (1) straight after the topic sentence because efficiency sounds like the headline benefit.
• Leaving It eliminates (3) until last, far from the noun it stands for.
