Mini Quiz
A quick check on Cohesion Mastery — a full quiz sits inside every lesson.
C2 · Cohesion Mastery
Choose the most cohesive continuation of: 'Applications doubled in a single term.'
Why. Structure: this / these + summarising noun. 'This growth' packages the previous clause into a clear noun phrase. Bare 'this' leaves the reference unlabelled, and 'they' has no plural antecedent in the first sentence.
