Find the gap between a claim and an explanation
Consider this sentence: “Governments should invest in buses because this is good for people.” It states a preference but leaves the benefit undefined. Adding “very good” or a more formal synonym does not close that gap.
Choose one benefit and explain how it happens
One possible benefit is a more reliable commute. A possible explanation is that more frequent buses reduce long waits. Together: “More frequent buses can make commuting more reliable. When passengers can reach work without long waits, public transport becomes a practical alternative to driving.”
This development adds a specific line of reasoning. Check that you actually agree with it and that it answers the question. You could instead argue about accessibility or congestion, but each choice would need its own explanation. You do not need invented research or statistics.
Use three questions as a drafting check
- What precisely improves, becomes harder or changes?
- What causes that change?
- How does it support my answer to this question?
These questions are a checking tool, not a fixed paragraph template. Some ideas need an example; others need a qualification. Avoid adding sentences merely to reach a formula.
Try it with a different idea
Write two sentences explaining why a city might invest in cycle lanes. Identify one benefit and explain its mechanism. Then remove any phrase that could apply equally to almost any topic, such as “good for society”.
Review your attempt
Underline the specific benefit and circle the explanation of how it happens. If the two do not connect, revise the reasoning before changing vocabulary. Ask another reader to explain your point back to you.
