How can you help missionaries value getting asked questions?

Missionaries want to proclaim the good news of Jesus. So, they do evangelism, baptize and disciple believers, and preach during worship services. God uses these activities to build His kingdom. These activities tend to flow from an advice-giving paradigm, rather than a question-asking paradigm.
