Question
Read the given statement and inferences carefully.
Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given inferences can be derived from the statement. (An inference is something which is not directly stated but can be derived from the given facts/information in the statement.) Statement: All mammals are warm-blooded animals. Inferences: I. Dogs are warm-blooded animals. II. All warm-blooded creatures are mammals.Solution
From the statement "All mammals are warm-blooded animals," we can derive the following: I. Dogs are warm-blooded animals. This is a valid inference because dogs are a type of mammal, and mammals are warm-blooded animals. Therefore, statement (I) is correct. II. All warm-blooded creatures are mammals. This is not a valid inference. While all mammals are warm-blooded animals, not all warm-blooded animals are mammals. Birds, for example, are warm-blooded but are not mammals. Therefore, statement (II) is incorrect. So, the correct answer is: 4. Only (I).
