It says heavenS not Heaven. The Bible probably means the sky and the celestial bodies, not actual Heaven. Isn't Heaven usually capitalized?

The idea is, use "an" because the h is very soft to the ear. An historian. But a whole lot of refined educated people say "a historian,." because the h isn't really silent...you can hear the soft h consonant.  The "an" before h+vowel rule is a loosey-goosey one...not many people use it and as you point out, it doesn't work. One of the oddities/challenges of our language. Personally, I don't follow it.

I know what you mean.\n\nThe letter 'A' is not in the spelling of the numbers 1 - 100. \n\n\n\n--- LeeeN

The word "I" in English is from the German "ich." When the printing press was invented, it was too difficult for the printer to insert a lowercase i because the block containing the letter was so small. And a lowercase i was difficult to read. So, printers began using an uppercase I, and we still use it today! By the way, I is NOT a proper noun; it's a pronoun.

my experience would tell me to use "an" because opossum starts with a vowel - I prounounce it with the "o"\n\nthe "o" is silent in some accents, I think it depends where you are from, what your accent is, and how you pronounce words :-)

The Truth Behind the Pen Name is correct if that is the title of an essay or story.\n\nIf you are using it as a sentence and not as a title, then the proper capitalization is \n\nThe truth behind the pen name.\n\nHope this helps.

It starts with an "A". I think you need to be a bit more specific.

Although you did not write the whole sentence, from the beginning few words it does seem that the "p" should be capitalized because it refers to the actual president as a person.  If you are referring to the position in general, without respect for who is currently in the role, you do not capitalize it. Of course, lines do get fuzzy sometimes on the last rule, but in your case, it should have been capitalized.  \n\nHowever, it's not the first time the Post has had some difficulty with grammar. I've seen several occasions of fragments that show lack of proofreading. \n\nGood question though!

The Internet is a specific place, like Japan, New York, Main Street or First National Bank. In English, specific places are capitalized.

Not unless it is a proper noun. (A name or title.)\n\n EX: "The Bank of Democracy" is capped cuz it's a name, but\n\n"The U.S. is a democracy."  is not capped!

In your example, both "Hill" and "House" are proper names, so they'd both be capitalized.

Because it is plural.  In spanish if you abbreviate something in plural you double the initial.

Yes, it's capitalized, because it's a proper noun.\n\nThe other isn't one word it's two words, thanks giving.

In an element symbol, only the first letter is a capital letter...any later letters are lowercase.  There aren't any exceptions.\n\nCould you give a specific example of which element symbol you're looking at?  Perhaps you're mistaking a compound chemical formula for an element symbol.  For example, CO is carbon monoxide, a compound.  Co is cobalt, an element.
