Final answer:
Yes, Mozart's "Jupiter Symphony" was indeed his last and is his longest symphony, completing it in 1788. Composers like Strauss and Beethoven have also influenced the arts, with their music being used in iconic films by Stanley Kubrick.
Step-by-step explanation:
The statement that Mozart's "Jupiter Symphony" was his last and longest is true. This symphony, which is Symphony No. 41 in C major, was completed in 1788 and is known for its complexity, intricate counterpoint, and majestic sound. It is nicknamed Jupiter for its grandeur. Although Mozart is well-known for his symphonies, other classical composers such as Strauss and Beethoven have also had significant impacts on music history. For instance, Stanley Kubrick famously used Strauss's Thus Spake Zarathustra and Beethoven's Ninth Symphony in his films 2001: A Space Odyssey and A Clockwork Orange, respectively, to heighten the dramatic effect of the visuals.
