Answer:
The sentence that best supports the conclusion that Arturo's perspective on life contrasts with his abuelo's is:
And I think that he could’ve been a teacher if he had wanted to bad enough.
This sentence implies that Arturo values education and sees it as an important career path, while his abuelo did not pursue it even though he had the potential. This suggests that Arturo and his abuelo have different perspectives on the value of education and career aspirations. The other sentences do not provide direct evidence of a contrast in perspectives between Arturo and his abuelo.
