Answer
Explanation:
Step1: Analyze first - set of statements
Let (C) be the set of coffee with cream and sugar. The first premise says the person's coffee is not in (C). The second premise says the person is drinking coffee. The conclusion that there isn't cream and sugar in the coffee follows from the first premise.
Step2: Analyze second - set of statements
Let (R) be the set of ranchers and (D) be the set of city - dwellers and (M) be the set of models. The first premise is (R\cap D=\varnothing), the second premise is (M\subseteq D). If (M) is a subset of (D) and (R) has no intersection with (D), then (R\cap M = \varnothing), so the conclusion that no ranchers are models is valid.
