An argument is a set of statements that consists of a conclusion and the statements said by the arguer to lead to that conclusion. Types of Reasoning Characteristics Example Deductive Deductive argument helps us to know what is contained in the premises, i.e., the meaning of the premises. A deductive argument is tautologous. It means that it is always true A deductive argument makes the claim that its conclusion is supported by its premises conclusively. The conclusion follows from the premise/premises necessarily. Premise 1: There are 24 CDs on the top shelf of my bookcase and 14 on the lower shelf. Premise 2: There are no other CDs in my bookcase. Conclusion: Therefore, there are 38 CDs in my bookcase. Analogical An analogical argument is an argument in which one concludes that two things are alike in a certain respect because they are alike in other respects. Hence, we can conclude that the above example comes under the category of Analogical Argument. To suppose that the earth is the only populated world in the infinite space is as absurd as to assert that in an entire field of millet only one grain will grow. x Astronomical is the word relating to astronomy. Whereas, Astronomy is the study of the universe and its contents outside of Earth's atmosphere. Anthropology, “the science of humanity,” which studies human beings in aspects ranging from the biology and evolutionary history of Homo sapiens to the features of society and culture that decisively distinguish humans from other animal species. Hence, one can easily negate Astronomical and Anthropological as the answer.
