Question 3

Find the odd one out.&#10;A)implication&#10;B)disjunction&#10;C)negation&#10;D)argument

Accepted Answer

Implication, disjunction, and negation are all logical operators or connectives used in logic and mathematics to form propositions or statements. An argument, however, is a set or series of statements typically used to persuade someone of something or to present reasons for accepting a conclusion. It is not a logical operator.

Question 4

The components of conjunction are called _________.&#10;A)terms&#10;B)disjuncts&#10;C)conjuncts&#10;D)none of these

Accepted Answer

The components of a conjunction are called conjuncts. In logic and grammar, a conjunction is a compound statement formed by combining two statements with the word "and," and each of the combined statements is referred to as a conjunct.

Question 5

'It is not the case that Raju is honest' is a ------ proposition&#10;A)atomic&#10;B)compound&#10;C)general&#10;D)none of these

Accepted Answer

The statement "It is not the case that Raju is honest" is a compound proposition because it contains a negation of a simpler statement, making it more complex than an atomic proposition.

Question 6

The statement form with both true and false substitution instances is called _________.&#10;A)contradiction&#10;B)contingent&#10;C)conjunction&#10;D)tautology

Accepted Answer

A contingent statement is one that can be true in some situations and false in others, depending on the truth values of its components. Contradictions are always false, tautologies are always true, and conjunctions depend on the truth values of the combined statements but are not defined by having both true and false instances.

Question 7

Modus Tollens means denying the ________.&#10;A)antecedent&#10;B)consequent&#10;C)both (a) and (b)&#10;D)none of these

Question 8

'It is not the case that Ramesh is honest' is symbolised as ------&#10;A)r&#10;B)~ r&#10;C)r . h&#10;D)none of these

Accepted Answer

The statement 'It is not the case that Ramesh is honest' negates the proposition of Ramesh being honest. In symbolic logic, the tilde (~) represents negation. Therefore, if "r" symbolizes "Ramesh is honest," then "~r" correctly symbolizes the negation of that statement, meaning 'It is not the case that Ramesh is honest'.

Question 9

If we can construct a formal proof , the argument is _________.&#10;A)invalid&#10;B)false&#10;C)true&#10;D)valid

Accepted Answer

If a formal proof can be constructed for an argument, it means that the conclusion logically follows from the premises, making the argument valid.

Question 10

Modus Ponens means _______ the antecedent and the consequent.&#10;A)affirming&#10;B)constructing&#10;C)denying&#10;D)none of these

Accepted Answer

Modus Ponens is a form of argument in logic where one affirms the antecedent to conclude the consequent. It follows the structure: If P, then Q. P is true, therefore Q is true.
