Final answer:
The statement describing a composer with works including ballets, symphonies, concertos, and film scores is true, as it fits the profiles of several composers from the Romantic era to modern times.
Step-by-step explanation:
The question pertains to a composer whose body of work includes ballets, symphonies, concertos, and a significant number of film scores. This description is accurate for several composers throughout music history, particularly from the Romantic era and beyond.
Notable examples from the Romantic period include Tchaikovsky and Strauss. Also, modernist composers such as Igor Stravinsky, whose revolutionary work in ballet such as 'The Rite of Spring,' made waves beyond standard concert halls. However, the statement could also apply to composers who have made a significant impact on film music, such as John Williams or Ennio Morricone in more recent times.
