Explanation : Converse of a proposition: Swapping the
subject with the predicate.
Thus, the types of proposition have their
converse as follows:
A (All S are P): All P are S.
E (No S are P): No Pare S.
I ( Some S are P): Some P are S.
O (Some S are not P): Some P are not S.
Explanation : The following modes of communication
can be employed in the classroom:
• Top-down (issuing instructions and
information in a hierarchical structure)
when the teacher transacts a lesson using a
teacher-centred method such as lecturing
• Iconic (based on images rather than text)
• Abstract (through stories, metaphors,
allegories, and examples, with emphasis on
the specific rather than the general)
While dissociational communication
would cause a disconnect between the
teacher and the taught, associational would
create association with some and distance
others. Symbolic communication would
compromise clarity and understanding.
Explanation : Academics is a formal process of learning
which requires a certain level of decency
and decorum for desired outcomes to follow.
Slang is use of informal words and phrases
which would certainly undermine the
cultivated atmosphere of the classroom. So ,
Assertion (A) is false and Reason (R) is true.
Explanation : Voice modulation (or varying the speed,
pitch and tone) in teaching is a technique
that keeps the learners' interest fastened on
the teacher and make teaching effective.
On the other hand, slow expression of
words might make fast learners impatient,
presentation without pause may steal
the valuable moments of reflection from
the students, and resorting to semantic
jugglery (play with words) may undermine
comprehension.
Explanation : According to classical Indian school of
logic, Anumana or Inference is the second
of the pramanas, or the five means of
knowledge. It occupies a central place in the
Hindu school of logic (Nyaya). This school
worked out a syllogism in the form of an
argument that goes through five stages: (1)
the proposition (pratijna), (2) the ground
(hetu), (3) the illustration (udaharana),
(4) the application (upanaya), and (5) the
conclusion (nigamana).
