Task 63: Writing a Complete Problem-Solution Chain

Write a passage that traces a problem to its root cause, a solution, and its trade-offs — the full chain Lesson 63 taught you to reconstruct when reading.

Learning Objectives

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

  • Separate a symptom from its root cause
  • Choose a solution-strength verb (reduce, mitigate, eliminate) that matches the actual outcome
  • State a trade-off honestly rather than presenting the solution as costless

Introduction

Lesson 63 taught you never to stop at "what is the solution?" — but to trace the full chain: problem, root cause, solution, outcome, and trade-off. This task asks you to build that chain yourself, choosing your solution-strength verb carefully rather than defaulting to "solved."

The Rule, for Writing

Core Concept

State the symptom, then the root cause behind it (not just the symptom restated). Name the solution and pick your verb honestly: "eliminated" only if the problem is fully gone, "reduced" or "mitigated" if it's smaller but still present. Then state one real trade-off — cost, speed, or complexity the solution introduced.

Example

Late deliveries were traced not to traffic, but to an outdated route- planning system. A new routing algorithm reduced average delivery delay by 30%, though it also increased fuel costs, since routes now prioritised time over distance.

Describe a real or realistic problem in your field, its root cause (not just its symptom), the solution applied, and one honest trade-off. Use a solution-strength verb (reduced, mitigated, eliminated, prevented) that matches what actually happened — don't default to "solved" unless the problem is genuinely gone.

Vocabulary in Context

root causenoun phrasetechnical

the underlying reason behind a problem, as opposed to its visible symptom (মূল কারণ)

Often with root cause analysis, identify the root cause, underlying root cause

“The root cause of the delays was a shortage of trained operators.”

mitigateverbformal

to make a problem less severe, without necessarily removing it (প্রশমিত করা)

Often with mitigate the risk, mitigate the impact, partly mitigate

“A backup generator mitigates the risk of a power failure.”

Model Answer

Show a model answer

Frequent stockouts at the warehouse were traced not to demand forecasting, but to a slow manual reorder process that left gaps between running low and placing a new order. An automated reorder system reduced stockouts by roughly 40%, since orders now triggered the moment stock crossed a set threshold. This did not eliminate the problem entirely — unusually large, unpredictable orders still slip through occasionally — and it introduced a new trade-off: the warehouse now carries slightly higher average stock levels, which increases storage cost.

Self-Check

Self-Check

  • Did you name the root cause separately from the visible symptom?
  • Did your solution-strength verb (reduced/mitigated/eliminated) match what actually happened, not just what was intended?
  • Did you state one honest trade-off rather than presenting the solution as free?
  • Did you write directly in English, without composing the paragraph in Bangla first?
