Two statements are given followed by three conclusions numbered I, II, and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: 1. All utensils are spoons. 2. All bowls are spoons. Conclusions: I. No utensil is a bowl. II. Some utensils are bowls. III. No spoon is a utensil.
The value of the definite integral
