Let's say my friend gave me a task to find something in a book.
I opened the book and started looking through the chapters to find the answer
I opened the book and started looking through the pages to find the answer
I opened the book and started looking through sentences to find the answer
I opened the book and started looking through words to find the answer
According to some linguists, the use of "the" can depend on how strongly the noun in question is expected in a given context. For example, when I am talking about a particular book, it's highly likely that I should say "the chapters" or "the pages".(the ones that are in this book) Because chapters and pages are quite an important part of any book and it's one of the likely associations that come to mind when we hear the word "book". (same goes for "car" and "the wheels", for example")
My belief is that the best choice of articles here is "the books" and "the chapters" but zero for "sentences" and "words" because they are less closely associated with the concept of book (or maybe it has to deal with words and sentences being too numerous and seemingly infinite in a given book i.e. we can't imagine even an approximate amount of them)
What are the best choices of articles in these 4 sentences? the/the/zero/zero?
