UGC NET Paper1 Previous Year Solved Papers - 6th December 2019 Morning Shift
- 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.
| 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.
- 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.
