To clarify the meaning of 'unruly' in the article, a sentence should be added that gives a clear example or definition of the term, demonstrating its meaning as 'disorderly, disruptive, and not easily controlled'.
Step-by-step explanation:
Adding a sentence that provides a clear definition or example of the term 'unruly' would help to clarify its meaning in the context of the article. For instance, if we include the sentence 'John was an unruly child, often breaking rules and refusing to listen to his teachers', it would bring out the definition of the word as 'disorderly and disruptive and not amenable to discipline or control'. As such, learners would be able to understand that in the context of the article, 'unruly' is likely describing a situation or individual that is hard to control or manage.
