four essential Qs

1.I was looking for the word "heaven" in a dictionary and it noted  that it is an uncountable and a proper noun if used in religious context. My question is why it as a proper noun seldom capitalized? A  proper name needs to be capitalized but I seldom see the word "heaven" capitalized. Why? eg, "Our father is heaven, give us our daily bread ..." Yes, a proper name should be capitalized, but "heaven" and "hell" are generally lower-cased. Some place names are a little ambiguous in that. Some people refer to "The South" meaning the southern (and actually eastern) part of the U.S., and sometimes it's capitalized, but sometimes now. Also, what word should I use to better convey the intended meaning for the word "noted"? Noted seems like the right choice. Can I change the underlined "religious context" as "a religious context" and will it be OK? In fact, it seems to call for the "a." 2. Is the sentence has the word "the" because the noun it is modifying is being restricted subsequently by the underlined phrase? Yes. What kind of learning? The learning that occurs during this activity. This validates the importance of the learning that occurs during this activity.  3. Is the article "the" optional? No, I think it's required. But it's an odd sentence, like it's an answer to a question. "What are Madrid, Bangor, Paris, and Calais?" "They are the names of towns in this area. (By the way, they're all in Maine.) They are (the???) names of towns in the area. 4. Why in this case, the made-up proper noun are not being modified with the article "the" when the "passport" seems to necessitate the inclusion? I would agree that the "the" seems necessary. Or "an." You need first get (the????) LCI Passport before you can use our service.
