Rules for Syllogism:​

One can face a lot of issues concerning the kind of sentence that may lead to the kind of conclusion. However, if you are thoroughly well aware of the rules mentioned below along with their correct use, then you are expected to commit no blunders while solving the questions. Check out the below rules:

–> Universal Positive Statement

To begin with universal signifies something that is appropriate to all as well as optimistic ways, such as the ‘yes’ kind of format. A universal positive statement specifies a little positivity relevant to all the things in that group. The positive category is signified by the alphabet ‘A’. These statements begin with All, Each and Every.

–> Universal Negative Statement

In this situation, the mere dissimilarity from the last type is that, in this situation, the sentence carries a negative meaning. It implies that it refers to that kind of sentence, which is common and giving a pessimistic expression. Such kinds of sentences start with No, Not a single, None of the, and more. These sentences are denoted by the letter ‘E’.

–> Particular Positive Statement

In this situation, the given sentence offers a positive expression, however, it includes only a few things and not all. These kinds of sentences often starts with some, a few, any, and are symbolized by the letter ‘I’.

–> Particular Negative Statement

Here, the statement again covers only some items, but it gives a negative impression. These kinds of sentences are symbolizes by the letter ‘O’.

  • When there are two specific sentences, no universal assumption is imaginable.

  • When there are two specific sentences, no assumption can take place, apart from when an ‘I’ kind of sentence is provided as well as by retreating it an ‘I’ kind of assumption can be done.
