Task 68: Writing a Rule with a Genuine Exception

Write a rule paragraph that keeps an exception, a limitation, and a precaution clearly separate — the distinctions Lesson 68 taught you to read.

Learning Objectives

By the end of this task, you should be able to:

  • State a main rule, then a genuine exception that excludes a specific case from it
  • Distinguish an exception from a limitation and from a precaution
  • Describe a fallback path for when the normal rule fails

Introduction

Lesson 68 taught you to separate a genuine exception (excluded from a rule) from a limitation (a real constraint on capability) and a precaution ("in case," preparing for something that may never happen). This task asks you to write a rule paragraph that keeps all three distinct.

The Rule, for Writing

Core Concept

State the main rule plainly. Add one true exception ("except when...") that carves a known case out of the rule. Add one limitation ("the system cannot..." — a real constraint, not an exclusion). If relevant, add a precaution ("in case...") for something that might happen, not something that already applies.

Example

All containers are inspected on arrival, except those already sealed by customs. The scanner cannot detect certain organic materials — a genuine limitation, not an exception. Staff carry a manual override device in case the automated system fails.

Write a short rule paragraph for a real or realistic process. Include: one main rule, one true exception ("except when..."), and one genuine limitation of the system or process (something it simply cannot do, not something excluded from the rule). Optionally add a precaution.

Model Answer

All export documents are verified electronically before release, except when the exporting country has no digital verification system in place, in which case a manual check applies instead. The verification software cannot currently read handwritten annotations reliably — a genuine limitation, not something the policy excludes on purpose. As a precaution, staff also keep a printed backup of every verified document in case the digital system goes offline unexpectedly.

Self-Check

Self-Check

  • Did your exception carve out a specific, known case rather than restating the limitation?
  • Did your limitation describe something the system genuinely cannot do, not an excluded case?
  • If you included a precaution, did it prepare for something that might happen, not something already true?
  • Did you write directly in English, without composing the passage in Bangla first?
