Answer:
They parallel Stanley's wish that things had turned out differently for him.
Explanation:
Louis Sachar's "Holes" revolves around the wrongful accusation against the protagonist, Stanley Yelnats who was put in a detention center. And it was in this detention camp that they were made to dig holes all day, without really knowing what they were looking for.
The change in the lyrics sang by Sarah shows the predicament that her great-great-grandson Stanley will be in. Sarah sang the song about the pig stealing Yelnats that began the 'curse' on the family. And the <em>"if only"</em> of the song parallel Stanley's wish for a different outcome of his life.
Thus, the <u>correct answer is the last/ fourth option</u>.
