Answer:
Number 1 is the opinion.
Explanation:
Number 2, Number 3, and Number 4 all are supported with sufficient evidence. 
In Number 2, the passage refers to a real-life property, the "intellectual property", and therefore supports the sentence, providing a clear argument that the song is copyrighted. 
In Number 3, the passage refers to judges and juries comparing different parts of the song. This is also what would happen in a real-life situation since copyright laws have strict policies equipped within them.
In Number 4, it provides an exact date to when the incident happened with Katy Perry and the people who have worked with her. 
However, in Number 1, only because "the melody of the two songs sounding different" is not sufficient evidence for the audience to believe that the song is not copyrighted. More evidence is needed in order for this claim to be stronger.
