If she's going to read her propaganda to your child, then perhaps you should read something to her that isn't propaganda.
Or, alternatively, knowing the way the WTS uses leading questions in its indoctrination material, maybe your daughter could do with some gentle de-briefing, asking her how the chapter made her feel and letting her know that while it's ok to learn about what people believe, it isn't necessarily true (like Santa Claus - your wife will approve of that) but it's each person's responsibility to figure out what they want to believe for themselves.
BTW, you might want to ix-nay the chapter about how Satan and the demons like it when we touch ourselves (Chapter 9 or 10 if I remember correctly) it's so NOT appropriate.
