Explanation:

From the different options listed below the one that is not a valid data source for mail merge is a database. This is because mail merge uses all the different Microsoft Word and Microsoft Excel types of documents, these include Outlook contacts , Excel worksheet , and even PDF document. Databases on the other hand are server-side programs that contain a wide range of information but are not considered to be a specific document type and therefore not accepted for mail merge.

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
