Explanation
Present continuous (is/are + verb-ing) is used for actions happening now. Present perfect continuous (has/have been + verb-ing) is used for actions that started in the past and continue to the present. 'Have been preparing' and 'have been rehearsing' indicate ongoing actions over weeks/days. 'Are organising', 'is growing', 'is testing', and 'is buzzing' describe current actions. 'Has been working' indicates continuous effort over time.
