Problem: “why” questions trap literal readers — the passage never says “because”, yet the answer exists in purpose and function. Answer in brief: why-answers live in purpose clauses (to…, in order to…, so that…), function descriptions (the role of…) and cause-effect structures. Hunt purposes, not becauses. This guide teaches purpose-hunting with a worked example, and OET Reading — Course 2 trains why-questions across 17 topic sections.
Purposes, not becauses
Passages state purposes as infinitives (“to reduce…”), function nouns (“the aim is…”, “the role of…”), and designed-for structures (“X is used to…”). Why-questions paraphrase these — “Why was the protocol changed?” answers to “to reduce overnight admissions”. Train eyes for purpose grammar and why-items answer themselves; hunt “because” and they hide.
Foundation example method
Study one fully-worked example per why-subtype (purpose, function, cause, reason-for-change) with the evidence underlined and the paraphrase mapped. Foundations show the complete reasoning chain once; subsequent practice imitates the chain. Example-first learning beats rule-first for why-items because the logic is recognition, not procedure.

Worked example: guideline purpose question
Fictional lines, newly written: “The overnight observation protocol was revised to reduce unnecessary admissions while maintaining safety…” Question: Why was the protocol revised? Chain: purpose infinitive located (“to reduce…”), paraphrase mapped (reduce = cut down), answer in passage words within limits. The full chain visible — purpose found, paraphrase matched, limits respected.
Guided practice method
Attempt with answers available but covered: answer first, uncover, compare reasoning (not just answers) — where did your chain diverge? Log divergence types (missed purpose grammar? wrong paraphrase? limit breach?) and drill the type, not the item. Guided practice with answers teaches chains; blind practice tests them.
FAQs
How do I spot purpose grammar fast?
Hunt infinitives, “aim/role/purpose” nouns and “used/designed for” structures during the first scan. Purpose grammar clusters near paragraph openings and guideline headers.
What about direct cause questions?
Same hunt, different grammar: “due to”, “as a result of”, “led to”, “attributed to”. Cause markers are rarer but more explicit — collect them as a set.
What is in the course?
Seventeen topic sections on why-questions with foundation examples and guided practice, 16 lessons and 5 complete mock tests.
The matching course
OET Reading — Course 2 answers why: purposes hunted, foundations studied, practice guided — 17 topic sections, 16 lessons, 5 mock tests. If why-items baffle, hunt purposes here.
