“Romeo and Juliet, Ballet Suite No. 2, Op. 64: I. Montagues and Capulets” by Sergei Prokofiev plagiarized?

The middle portion of “Romeo and Juliet, Ballet Suite No. 2, Op. 64: I. Montagues and Capulets” by Sergei Prokofiev sounds very similar to “Symphony No. 7 in A Major, Op. 92: II. Allegretto” by Beethoven. Is this coincidence, plagiarism, allowable use, or just an erroneous comparison on my part?
