Final answer:
An objective summary could include the sentence: Multiple stakeholders, including the President of Colombia, UNESCO, and Spain, have proposed different fates for the treasure and artifacts from the San José shipwreck, reflecting a complex international debate over cultural heritage and ownership.
Step-by-step explanation:
The paragraph describes different groups and individuals offering their ideas about what to do with the treasure from the San José shipwreck.
Firstly, it is mentioned that the President of Colombia proposes a museum to exhibit the artifacts.
Secondly, UNESCO has cautioned Colombia against using the shipwreck for commercial profit.
Lastly, there is a dispute over ownership, with Spain claiming the ship as theirs and others arguing that the treasure was looted from places like Peru and Bolivia, suggesting it should be returned there.
These conflicts highlight the broader issues of cultural heritage, rightful ownership, and the handling of artifacts from a historically and economically significant period.
Therefore, the objective summary could include the sentence: "different fates for the treasure and artifacts from the San José shipwreck, reflecting a complex international debate over cultural heritage and ownership and the multiple stakeholders."
