Direct answer

The cause-effect trap is listing results without explaining why they happen. What are the causes of X needs mechanisms, not a paragraph of problems with because inserted once. Why has Y increased needs causal links, not correlation (A rose when B rose, so B caused A). Examiners score Task Response on whether your essay shows cause → mechanism → effect, not whether you named many issues.

How cause-effect prompts are worded

Causes of / reasons for Explain why, not only what happens

Effects of / results of Trace outcomes from named causes

Problem-solution bleed Solutions paragraph on a causes-only stem

Traps that cap Task Response

Trap	Why it fails
Effect laundry list	Many results, no why
Correlation claim	Two trends named; causation assumed
Vague because	Because it is bad with no mechanism
Solution drift	Government should fix on a why-only prompt

Causal outline that holds

Intro: topic + preview 2–3 causes or effects. Body: one cause per paragraph with mechanism + example, or cause block then effect block if the prompt splits them. Use therefore / as a result only after the cause is clear. Conclusion: summarize chain, no new causes.

Key takeaways

Every effect needs a explained cause.
Avoid correlation dressed as causation.
Match essay type to prompt, causes vs solutions.
Test each because, can you explain how?

FAQ

Yes if they are closely linked and you explain the mechanism, avoid a bullet list of unrelated outcomes.

No. Cause-effect explains why something happens; problem-solution focuses on problems and fixes unless the prompt asks for causes.

No. Clear logical examples are enough; invented numbers hurt credibility.
