Concept:In syllogism, "Only a few $A$ are $B$" means some $A$ are $B$ and some $A$ are not $B$.Formula:Complementary pair: "Some $A$ are $B$" and "No $A$ is $B$" form an either-or pair.Solution:Given: Some tata are bmw.Given: Some bmw are audi.There is no definite relation between tata and audi.So conclusion I, "Some tata are audi", is not definite.Conclusion II, "No tata is audi", is also not definite.But conclusions I and II are complementary.Hence either I or II follows.Shortcut:Focus only on tata and audi.I says some tata are audi.II says no tata is audi.These two cover all possibilities, so either-or applies.Answer:C. If either conclusion I or II follows.
