Task 62: Narrating Change Over Time
Write a short passage that traces a process or development through time — separating clean sequence from a genuine causal claim, the way Lesson 62 taught you to read one.
Learning Objectives
By the end of this task, you should be able to:
- Sequence several stages of change using explicit time markers
- Mark a genuine causal link differently from mere chronological order
- Identify at least one turning point in the process being described
Introduction
Lesson 62 taught you to read a passage in motion — to build a timeline, spot turning points, and never assume that "then" means "because of." This task asks you to write that kind of passage yourself: a short account of a process or change that keeps sequence and causation cleanly separate.
The Rule, for Writing
Core Concept
Order events with explicit time markers (initially, by the following year, eventually), then only claim causation where you can defend it — use "which led to" or "triggered" for a real causal link, and a neutral "after this" or "around the same time" when you only know the order, not the cause.
Example
The terminal initially processed all bookings manually. Within two years, a digital booking system had been introduced, which reduced average processing time by half. Around the same time, the port also adopted new customs software — though the two changes were not directly connected.
Your Turn
Your Turn
Describe a real or realistic process of change in your field over several stages (e.g. how a system, a role, or a procedure evolved). Use at least three explicit time markers, name one clear turning point, and use one strong causal verb (triggered, led to, resulted in) for a link you can actually justify — while marking anything you're not claiming caused the next stage as merely sequential.
Vocabulary in Context
turning pointnoun phraseneutral
the moment a process changes direction or accelerates (মোড়ঘোরানো মুহূর্ত)
Often with a turning point, mark a turning point, critical turning point
“The canal closure was the turning point that reshaped shipping routes.”
triggeredverbformal
directly caused something to start happening (সূচনা ঘটানো)
Often with triggered by, triggered a review, directly triggered
“The failed audit triggered a full regulatory review.”
Model Answer
Show a model answer
The warehouse initially tracked inventory using paper logs. By the second year of operation, a barcode scanning system had been introduced, which reduced counting errors by nearly a third. The real turning point came the following year, when a stock shortage triggered a full switch to real-time digital tracking. Around the same time, the company also relocated to a larger facility — though this move was not directly caused by the inventory changes, the two happened to overlap.
Self-Check
Self-Check
- Did you use at least three explicit time markers to order the stages?
- Did you name one clear turning point?
- Did you use a strong causal verb only where you could genuinely justify it, and mark anything merely sequential as such?
- Did you write directly in English, without composing the paragraph in Bangla first?
