Rearrange the following sentences to form a coherent paragraph: 1. This process, a crucial part of the plant’s life cycle, is vital for the continued existence of many plant species. 2. Pollination is the transfer of pollen from the male part of a flower to the female part. 3. The transfer can be carried out by various agents, including insects, birds, and wind. 4. Successful pollination leads to fertilization and the subsequent production of seeds and fruits.

Correct — A. Start with the sentence that points back to nothing.

2 opens: it defines pollination from scratch.
3 follows: The transfer picks up 'the transfer of pollen' from 2.
4 gives the result: pollination leads to fertilization, seeds and fruits.
1 closes: This process sums up, and it says why the chain is vital for the species.

Order 2, 3, 4, 1 → option (a).

Why the others are wrong

• (b)
  3, 4, 1, 2 — Opens with The transfer, which needs 'transfer of pollen' before it, and ends with the definition of pollination after the passage has already used the word.
• (c)
  1, 2, 3, 4 — Opens with This process, which has nothing to point back to. The definition in 2 must come before any sentence that refers to it.
• (d)
  4, 1, 2, 3 — Opens with Successful pollination and its result before pollination is defined, then defines it third. The result cannot come before the definition it depends on.

In a jumble, look first for back-pointers: pronouns, this, or the + a noun already used. A sentence that leans on one needs something before it.

Here This process (1) and The transfer (3) point back, and 4 uses pollination as a known term. Sentence 2 is the definition, so it opens.

After it the chain runs: definition → how it happens (agents) → what it leads to (seeds, fruits) → why it matters (the survival of species).

Key facts

• Pollination is the transfer of pollen from the anther (male part) to the stigma (female part) of a flower.
• Agents of pollination include insects, birds, wind and water.
• Pollination is followed by fertilization, after which seeds and fruits develop.

Common traps

• Opening with 1 because it sounds like a topic sentence. This process needs a noun before it.
• Wanting 1 straight after 2 because This process means pollination. No option offers 2 then 1, and the significance reads best after the result in 4.
