Which of the following sentences does NOT belong in a well-organized paragraph?

The sentence "Spain, a European country, has a population of forty-six million" does not belong in a well-organized paragraph.
The paragraph is about a restaurant called Aceituna, which claims to serve authentic Spanish food. The paragraph then goes on to say that the food at Aceituna is inedible and that the restaurant is not the place to go if you're looking for real Spanish food.
The sentence about the population of Spain is irrelevant to the topic of the paragraph. It does not provide any information about the restaurant or the food that it serves. It is also out of place chronologically, since it comes before the sentence about the restaurant's recent opening.
