How about,
"Would you not agree...."
"Should"
"Train our thinking..."
Any study questions that asks how the reader should FEEL or ACT. For example, from WT April 1, 2007, page 30 "How can we demonstrate our obedience and submission?" "What should be our attitude toward our overseers?"
The language of the Watchtower is often in the third person, and passive. Big words are used when little would do. This type of writing clouds meaning rather than clarifies. This writing style would never pass in a secular publication.
An example of third person,
Nurse Chappell. "Now, how are we feeling this morning Mr. Brown?"
Does Nurse Chappell really want to know how she is feeling? Then why would she phrase her question this way? It's an attempt to set up a connection with the patient that does not exist. Also, to directly ask the patient how he is feeling may set in motion a cascade of emotion that Nurse Chappell is not prepared to deal with.
I've also seen the Watchtower place "quotes" if they want to imply that the bible really isn't saying plainly what it appears to be saying. It's a signal that the reader is not to take those words literally.
