I apologize for the confusion. The main source of a claim can vary depending on the context and the nature of the claim being made. It could be a combination of different factors, such as reliable sources, personal perspective, definitions of important words, or information from magazines, encyclopedias, and websites. The specific source can differ from claim to claim.
