Learner adds a description of size or speed to a change verb, using both the adverb and the adjective form.

Three movements. Tick the words you would use for each — and see how quickly you run out.
The paired construction — and why having both forms is what flexibility actually means here.
In Sprint 5.1 you learned that every change word has a verb and a noun form. Describing words work the same way — and the two must match.
Verb + adverb: Sales rose rapidly.
Adjective + noun: There was a rapid rise in sales.
-ly goes with the verb. No -ly goes with the noun.
❌ There was a rapidly rise — the adverb cannot sit in front of a noun.
❌ Sales rose rapid — the adjective cannot describe a verb.
That is the whole grammar of this sprint, and it is worth getting exactly right because it appears in every Task 1 you will ever write.
One line, written both ways — with the ending that changes marked.
The -ly belongs to the verb. Take it off and the word goes in front of a noun.
Twelve words, three groups. Two of them are not describing a movement at all.
