Question 1

Explanation

Unfortunately, as an AI language model, I cannot determine the correct proposition between 10 and 20 and 30 and 40 without additional context. However, I can provide an answer to the question "What is the maximum number of data sources that can be blended in Tableau CRM?" The maximum number of data sources that can be blended in Tableau CRM depends on the edition of the software being used. In the Professional and Enterprise editions, up to 35 data sources can be blended. In the Developer edition, up to 10 data sources can be blended. Blending data sources in Tableau CRM allows users to combine data from multiple sources into a single view or dashboard. This can be useful for analyzing data from different departments or systems within an organization. However, it is important to note that blending data sources can also impact performance and may require additional resources to maintain.
