Distinguish necessary from sufficient assumptions with an example.2.

A. Assumptions — the unstated machinery of argument An assumption is a claim the argument relies on but does not state. Types (the classification that earns marks):1. Cover/hidden premises (necessary assumptions) — without them the inference collapses:"The accused fled the scene; therefore the accused was guilty." Cover premises: [the guiltytypically flee], [the innocent typically do not] — each contestable; expose them and the argument weakens.2. Sufficient assumptions — a premise which, if added, would make the reasoning valid ("the argument assumes at least this much").3. Contingency assumptions — background bets about how the world behaves ("the courier is honest" "prices stay stable") — the stuff of transactional risk.The lawyer's uses: attacking an opponent's unspoken premise is often stronger than attacking the stated ones; and drafting (contracts, pleadings) is largely the discipline of making assumptionsexplicit — every "representations and warranties" clause is an assumption turned into a promise.B. Context — the argument's operating conditions No argument lives in a vacuum. Context includes: audience (bench, client, jury, public), purpose (persuade, advise, warn, deceive), genre (judgment, statute, editorial, gossip), and situation (a statement made under fear differs from one made at leisure). The same words ("I'll pay you tomorrow") are a promise, a pleasantry, or evidence depending on context. Statutory interpretation's context rule (words in their setting — the whole statute, its purpose)…
