Direct answer

The incomplete comparison trap hits when you write higher, lower, or while without finishing the comparison, no referent, no figure, no time frame. Task 1 rewards data relationships, not isolated adjectives. Examiners need to know higher than what, by how much, and when. Half-comparisons read like list transcription and cap Task Achievement at Band 6.

What makes a comparison incomplete

Missing referent Sales rose significantly, with no baseline

Missing data A was higher than B, no values attached

Missing contrast While X increased. Y change never stated

Incomplete comparison traps that repeat

Trap	Why it fails
Lone comparative	Reader cannot verify against the chart
While without pair	Only one side of the contrast developed
Rank without gap	Highest stated but not how much higher
Overview gap	Detail paragraphs compare; overview does not

Complete every comparison in one clause

Formula: subject + verb + comparative + referent + figure. Example: Coal consumption was twice that of gas in 2010. Pair with comparison language traps and overview missing comparison.

Key takeaways

Every comparative needs a referent and evidence.
While sentences must report both sides.
Overview must contain your main comparison.
Incomplete pairs cap Task Achievement.

FAQ

Yes in Task 1, every comparative needs a clear referent and supporting figure or rank.

Yes, but pair them clearly. A was highest, followed by B, with C lowest, not a vague cluster.

Maps need spatial change comparisons; processes need stage-to-stage contrast, same rule: complete the comparison.
