Final answer:
To avoid repetition from the previous sentence, 'Each' should replace 'Another' in sentence 3, indicating continuity and introducing a new musical instrument.
Step-by-step explanation:
To improve sentence 3 and avoid repetition from sentence 2 which already uses the phrase 'another fun percussion instrument to play', a substitution could be used for stylistic variation and to maintain reader interest. The word 'each' provides a sense of continuation and connection with the previous sentence, while also introducing a new instrument. Therefore, sentence 3 could be rewritten as 'Each fun percussion instrument to play is the tambourine.'
