What body paragraphs really asks you to write
A body paragraph makes one claim, explains why it holds, and shows it working. Each of those three moves has its own vocabulary, and the commonest failure is having only the first.
The difference between a list and a chain
A weak body paragraph states four things. A strong one states one thing and then follows it: because of this, which means that, which in turn produces this. The vocabulary of development is what turns the first into the second, and it is almost entirely made of linking phrases that name a consequence — “this stems from”, “as a result”, “which in turn”.
The reason this matters more than it sounds is that four asserted claims can all be true and still show nothing. An examiner reading them sees a writer who knows several things about the topic. A chain shows a writer who can reason, and reasoning is what the criterion calls development. It is also cheaper: one idea followed for five sentences fills a paragraph more convincingly than five ideas that each get one.
The opening sentence is what decides which of the two you get. A topic sentence that names one idea forces the rest of the paragraph to stay on it; one that names two gives you permission to drift, and the paragraph usually takes it.
Topic sentenceOne claim, and it should be arguable. If nobody could disagree with it, it is not a claim.
Development“this stems from”, “which in turn”, “consequently”. The words that turn a claim into a chain.
Support“a case in point”, “for instance”. Illustration, not proof — and never an invented statistic.
Return“this suggests that”, “it follows that”. Closing the paragraph on the claim it opened with.
Examples: illustration, not evidence
Task 2 gives you no sources and expects none. An example is there to make an abstract claim concrete — to show what it looks like when it happens — not to prove it. That distinction decides the vocabulary: “a case in point is” and “this can be seen in” are illustration, while “studies have proven that” and “according to a 2019 report” claim a source you do not have and cannot cite.
Invented statistics are the most damaging version of this, and they are common because they feel like rigour. “A recent study found that 73% of employees…” is a fabricated fact, and an examiner who has read four essays quoting four different invented percentages reads it as exactly what it is.
What it costs you to skip this
A paragraph of assertions with no development is the single most common shape in a mid-band response, and it is why the score does not move: everything in it is true, nothing in it is reasoned. And a fabricated source damages more than the sentence it sits in — it puts every other claim in the essay under suspicion.
Where it stops applying
Development has a natural end. Four links in a chain is usually one too many, and the last one tends to be the one you cannot defend. Examples have a limit too: one concrete case per paragraph is normally enough, and a paragraph that is mostly example has stopped arguing. And none of this vocabulary rescues a topic sentence that names two ideas — that has to be fixed at the top.
