The answer to the question: The olive oil bubbles in Lisa´s demonstration for the children represent the way..., is, C: Italians are able to completely change any culture they join.

Explanation:

The answer comes from the sentence itself. Olive oil is a product that is distinctive of the Mediterranean cultures, particularly the Italian culture. Because of the migration of Italians, especially during the two world wars, into  America, they brought with them their Mediterranean cuisine, and the ingredients for it, and made this one product very popular not just in the United States, but also in the world. Nowadays, it is very common to see olive oil being used almost in any household, and Italian cuisine has become one of the most popular as well. This shows how Italian influence on other cultures affects them deeply.
