Everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status. Furthermore, no distinction shall be made on the basis of the political, jurisdictional or international status of the country or territory to which a person belongs, whether it be independent, trust, non-self-governing or under any other limitation of sovereignty. (Article 2. UDHR)
Does "the rights" means "rights in this document" based on the context ("...in this Declaration")?
Furthermore, why does the text use definite articles for the words "basis", "country", "political status" if there are general concepts + we have a person so we can't use definite articles for countries and other general ideas.
As far as I know, using articles can sounds formal. Using articles has "its own style". In which situations can using articles sound either formal or neutral or informal? Could you recommend sources to me styles of using articles?
