Drill 63: Explaining a Problem and Its Solution Live
Trace a problem to its root cause, solution, and trade-off, out loud, live — no script, no Bangla translation step.
Learning Objectives
By the end of this drill, you should be able to:
- State a root cause aloud, distinct from the visible symptom
- Choose a solution-strength word (reduced/mitigated/eliminated) that matches what actually happened
- Name a real trade-off without being asked twice
Introduction
Lesson 63 taught you to reconstruct a full problem-solution chain when reading. This drill asks you to build one out loud, live, the moment a scenario is given — symptom, root cause, solution, and an honest trade-off, in one continuous explanation.
Shadow the Model
Late deliveries weren't caused by traffic. The real root cause was an outdated routing system. A new algorithm reduced delays by thirty percent, though it also raised fuel costs.
Notice the pace doesn't slow down for "root cause" or "reduced" — these are said with the same natural rhythm as the rest of the sentence, not carefully, word by word, the way a translated sentence often sounds.
Your Turn
Your Turn
You'll be given a short problem scenario. When the timer starts, speak: (1) the root cause, not just the symptom, (2) the solution and a solution-strength word that matches its real effect, and (3) one honest trade-off — all in one connected explanation, no planning pause.
Explain the chain now — no planning, just speak
Record Yourself
Explain the problem-solution chain, then record it and compare against the model.
Model Answer
Show a model answer
There's no single correct wording, but a strong answer names the root cause explicitly (not the symptom), picks a solution-strength word that matches the real outcome rather than defaulting to "solved," and states a trade-off without hesitating or needing a prompt.
Vocabulary in Context
symptomnounneutral
a visible sign of a problem, not the problem's underlying cause (লক্ষণ)
Often with a symptom of, obvious symptom, treat the symptom

Self-Check
Self-Check
- Did you name the root cause separately from the symptom, without being asked?
- Did your solution-strength word match the real outcome, not just the intention?
- Did you state a trade-off in the same breath, not as an afterthought?
