Which of the following is an example of deductive reasoning? a. all the houses in my neighborhood were built after 1980, so the houses on the next street over will have been built after 1980. b. every house we have lived in has been built after 1980, so the next house we live in will likely have been built before 1980. c. every house we have lived in has been built after 1980. so the nest house we live in will likely have been built after 1980. d. all the houses in my neighborhood were built after 1980, so the houses on the next street over will have been built before 1980.

The correct answer is A.

This is a correct use of deductive reasoning because it is logical to deduce that, if all the houses in the neighbourhood were built after 1980, the ones that are on the next street over (which is a part of the neighbourhood) will also had been built after 1980.

A. All the houses in my neighborhood were built after 1980, so the houses on the next street over will have been built after 1980.

Further Explanation:

This is called deductive reasoning because the logic has been derived from the circumstances surrounding the situation. Deductive reasoning is usually employed to obtain a conclusive and logical result from a group of statements. The logic is usually in accordance with the conditionals surrounding the statements. Deductive reasoning usually happens after careful consideration of all the various possibilities, and are interpreted on binary terms, whether it is true or false. If all the outcomes of the possible circumstances are true, then it provides for the drawing of a possible conclusion.

Deductive reasoning does not leave any room for uncertainty, which makes it imperative to draw a reductive conclusion after narrowing down to a variety of possibilities. In this case, we see that all houses in the neighborhood have been built after 1980, which is a circumstance, and the possibilities are that either house have been built after 1980, which tests to be true, and there are no houses that have been built after 1980, which tests to false. Thus, the possibility that will come out to be true will be considered as the correct logic. Now we shall understand the ways in which deductive reasoning will be evaluated. This is done by evaluating them in terms of their validity and soundness. An argument is valid only when the premises and conclusion of the argument matches with each other, and there is no ambiguity whatsoever. Thus, if the premises are true and the conclusion is false, the argument ceases to be valid.
