Answer:
I live in the city of Buenos Aires, capital of Argentina. It is one of the most populated cities in the world, with more than 17 million inhabitants, and one of the main tourist attractions in South America, with approximately 5 million annual visitors.
Its main tourist spots are related to the history of the nation and the arts: the Casa Rosada, the Plaza de Mayo and the Obelisk, in the historic center of the city; the Colon Theater, one of the main opera theaters on the continent; the La Boca neighborhood, the arrival point for the large number of Italian immigrants during the late 1800s and early 1900s; and the Recoleta Cemetery, a resting place for a large number of historical figures of the country.
Another contrast with licensure is that, under a licensing law, practitioners of the licensed occupation must have a license in order to practice. It is involuntary. On the other hand, certification is voluntary. One does not have to be certified in order to practice.
I believe it is D! I hope this helps : )
