Read the argument below: 'The customer support chatbot resolved 95% of user inquiries during testing last month. Therefore, it will perform just as effectively when deployed to handle all live customer inquiries next quarter.' Which statement is an underlying assumption of this argument, rather than an explicitly stated premise?

### Why this is right The material labels the belief that past issues predict future ones as an assumption. It is an unstated belief that helps connect historical data to claims about future chatbot performance. ### The concept A premise is stated as support, while an assumption is relied on without being stated as a supporting reason. The listed concerns about sample data, accuracy, and auditing are presented as premises. The prediction from past issues is a background belief that could be examined for support. ### The other options - **B. Sample data may not reflect real-world complexity.**: This is listed as a premise supporting the need for historical data. - **C. Safety-critical systems require high accuracy.**: This is also given as a supporting premise. - **D. Compliance auditing needs realistic scenarios.**: This is presented as another premise for the claim. ### Remember A premise is stated support; an assumption is a belief the reasoning relies on without stating it.
