Syllogism is a type of conclusion that is formed from two given or assumed propositions – a middle ground may be present in the premises but however not in the conclusion. It tests the deductive reasoning of the candidates. A conclusion can be deduced from a general statement and a specific statement which is also known as a major premise and a minor premise. A three-line format is generally followed to present a syllogistic argument.

Syllogism can seem to be airtight arguments but however there can be discrepancies within them if any one of the premises is found to be false or when the premises are not absolute, a faulty conclusion may be deduced.
