Which of the following is not described by gonzalo fernández de oviedo y valdés in la historia general y natural de las indias?

I think the question comes with the following options:

1) sandwhiches, 2)  hammocks, 3)  pinapples  4) barbeque

I am almost certain that the answer is sandwiches.

The reason for this is that all the remaining options are known to have the origin in the pre-columbian America, - Pineapples are native to Americas, barbecue was also first discovered when Columbus visited America and hammocks are known to originate in he native cultures.

In contrast, sandwiches are more of an Old World concept, so it's the best answer.
