If they call on me I cherish the opportunity to see that that JW can benefit. They will get a small handout that looks like:

When they get home and work up enough courage, they may look up the link at the bottom that takes them to THE GREAT WATCHTOWER CONTRADICTION, an 11 minute read where they can save it to their hard disk, bookmark it for future, etc.
The ones that have called here so far have all promised to get back to me to resolve those above conflicting articles in their own literature. They ask, of course, if it's all right with me to come back. My answer is always "yes, please do".
In the past several years some 5 have done this and I have yet to see a single one return.
