Does omitting the article in "The phones ring every six minutes." make the sentence more abstract?
For example, if I were to speak about the phones in my workplace, I could say "The phones ring every six minutes." A sentence like "Phones ring every six minutes." seems like a sentence used by who is reporting statistics.
Similarly, if I were to say "The dogs bark at every car." I could be speaking of dogs I (have) heard. With "Dogs bark at every car." I could be generalizing something I saw, even if I am not actually hearing any barking dogs, nor have I heard barking dogs in the past weeks; I could also be generalizing something other people experienced.
