21. "If it rains, then the drought will end. The drought has ended. Therefore, it rained". Which kind of fallacy does this commit?

  • Option : A
  • Explanation :
    This commits a deductive fallacy, formal fallacy, logical fallacy or non sequitur (Latin for "it does not follow"). It is a pattern of reasoning rendered invalid by a flaw in its logical structure -- fallacy wherein the conclusion does not follow from the propositions.

22. The smallest integer greater than 1 which is simultaneously a square and a cube of certain

  • Option : D
  • Explanation :
    Let the number 'k' is cube of number x and square of number (x + y).
    Then, k = x3   ... (i)
    k = (x + y)2   ... (ii)
    Here, 1 ≤ (x,y) < k/2
    From (i) and (ii),
    x3 = (x + y)2
    x3 = x2 + y2 + 2xy
    x3 - x2 = y2 + 2xy
    x2(x-1) = y(y + 2x)
    For x = 2, 22(2 - 1) = y(y + 4)
    This is not valid for any integer value of y.
    For x = 3, 32(3 - 1) = y(y+ 6)
    18 = y(y+ 6)
    This is not valid for any integer value of y.
    For x = 4, 42(4 - 1) = y(y + 8)
    48 = y(y + 8)
    48 = 4(4 + 8) = 48
    Thus x = 4,and y = 4
    Hence, Number k = (x)3 = (4)3 = 64.

23. Below are given two sets in which set I species the four behaviour modification techniques while set II indicates their exemplification. Match the two sets

Set I (Behaviour modification techniques) Set II(Example)
 (A) Positive reinforcement i.  Withdrawal of a pleasant stimulus or application of an aversive stimulus to stop the behaviour
 (B) Negative reinforcement ii. Painful or aversive stimulus is presented to stop the occurrence of behaviour
 (C) Punishment iii. The behaviour increases in frequency after the removal of the stimulus
 (D) Extinction  iv. The behaviour increases in frequency after the presentation of a stimulus

Choose your answer from the following options:

  • Option : C
  • Explanation :
    Positive reinforcement-The behaviour increases in frequency after the presentation of a stimulus
    Negative reinforcement-The behaviour increases in frequency after the removal of the stimulus
    Punishment-Painful or aversive stimulus is presented to stop the occurrence of behaviour
    Extinction-Withdrawal of a pleasant stimulus or application of an aversive stimulus to stop the behaviour

24. Swapping of encoder- decoder roles in communication happens due to

  • Option : C
  • Explanation :
    This can be understood in terms of teaching-learning in an educational institution.
    In the classroom the teacher is the encoder of messages and the student, the decoder. After the teaching, the encoder/teacher takes the feedback in the form of students' response-sheets to an assessment exercise/ test. When the encoder takes up the activity of analysing the feedback, i.e., checking! evaluating the responses, the roles of encoder-decoder stand swapped. Here, the students have encoded messages that the teacher has to decode.

25. A research scholar while nally reporting the research results in the form of a thesis acknowledge the support of his/her supervisor in the preface. This will be treated as a

  • Option : D
  • Explanation :
    Acknowledging the help, support and guidance availed in course of completing a research study is not just formality, nor a required formal process nor a superfluous act. It is part of ethicality involved in the research process. Research ethics are the moral principles that a researcher must follow in every way in every aspect of the research undertaken. Following ethical principles is indeed crucial for maintaining research integrity.
