UGC NET Questions (Paper – 1)

The wrong statement is D only. A, B, C, E and F are correct. D is false because a true conclusion can be reached via an invalid (fallacious) argument. F is correct because validity is a matter of logical form (truth-preservation across possible cases), not the actual truth or falsity of the premises in the real world.

Option A:
Option A is correct because it identifies D alone as wrong and correctly treats F as a true description of validity being form-based. This matches standard textbook definitions used in UGC NET reasoning.

Option B:
Option B is incorrect because it marks F as wrong, but F correctly states that validity depends on form, not on the actual truth/falsity of premises. So “F only” cannot be right.

Option C:
Option C is incorrect because it wrongly includes C as a wrong statement, even though C is the standard definition of soundness (valid + true premises). It also includes F, which is correct.

Option D:
Option D is incorrect because it includes F among the wrong statements. Since F is correct, the set “D and F only” is not the right answer.

The first-level differences are 9, 13, 17 and 21. These differences form an arithmetic progression with common difference 4. To continue this structure, the next difference should be 25. Adding 25 to the last term 67 gives 92, which maintains the regular growth among the differences.

Option A:
Option A gives 88, implying a difference of 21 from 67. This simply repeats the last difference rather than increasing it, so the progression of gaps 9, 13, 17, 21, 21 breaks the +4 pattern. Therefore 88 is not consistent with the rule.

Option B:
Option B gives 92, corresponding to a difference of 25. The differences become 9, 13, 17, 21, 25, which keep increasing by 4 each time. This perfect second-level arithmetic progression shows that 92 is the correct next term.

Option C:
Option C gives 96, yielding a difference of 29 from 67. The last jump among differences then becomes 8, which is double the expected 4 and disrupts the pattern. Hence 96 cannot be accepted.

Option D:
Option D gives 98, corresponding to a difference of 31 from 67. This further distorts the difference progression and makes the final step too large. Therefore 98 is not a valid continuation.

The consecutive differences are 12, 18, 24 and 30. These differences form an arithmetic progression with common difference 6. Therefore the next difference should be 36. Adding 36 to the last term 93 gives 129, so 129 continues the series in line with the observed second-level pattern.

Option A:
Option A gives 123, which implies a difference of 30 from 93. That would repeat the last difference and make the sequence of gaps 12, 18, 24, 30, 30, breaking the steady increment by 6. Thus 123 is not appropriate.

Option B:
Option B gives 126, corresponding to a difference of 33 from 93. In that case the last increase among differences would be only 3, not 6, distorting the structure. Therefore 126 does not fit the rule.

Option C:
Option C gives 129, implying a difference of 36 from 93. The difference sequence becomes 12, 18, 24, 30, 36, a clean arithmetic progression with constant step 6. This strong internal consistency makes 129 the correct next term.

Option D:
Option D gives 132, leading to a difference of 39 from 93. That makes the last increment among differences equal to 9, which is incompatible with the constant step of 6. Hence 132 cannot be accepted.

Statements A, C, D and E correctly describe statement–conclusion reasoning. A is true because a conclusion must be a reasonable inference from what is stated. C is correct in that valid syllogistic conclusions follow necessarily from premises. D is true; sometimes more than one conclusion is logically supported. E is correct because unsupported personal opinions do not qualify as conclusions based on the statement. B is false since a conclusion that contradicts the given statement is generally weak or invalid. Thus A, C, D and E only are correct.

Option A:
Option A is incomplete as it omits E, failing to emphasise that conclusions must be grounded in the statement rather than personal views, an important exam guideline.

Option B:
Option B is incorrect because it includes B, which wrongly treats contradictions as strong conclusions, and so mixes one false statement with true ones.

Option C:
Option C is wrong since it leaves out A and includes only C, D and E, thereby omitting the foundational idea of what a conclusion is in statement–conclusion questions.

Option D:
Option D is correct because it gathers all accurate points about necessity, multiplicity and support of conclusions, while excluding B, which misrepresents strong conclusions.

Statements A, D and E correctly describe the nature of statement–argument questions and strong arguments. Statement B is wrong because emotional appeal alone does not make an argument strong if it lacks relevance or logic. Statement C is also wrong since candidates are expected to interpret and infer implied strengths or weaknesses, not just copy text. Therefore, the wrong statements are exactly B and C, which makes their combination the correct answer for this “select the wrong” question.

Option A:
Option A is incorrect because it isolates B as the only wrong statement and ignores C, even though C clearly misrepresents the need for interpretation and inference in these questions.

Option B:
Option B is also wrong because it singles out only C and overlooks B, which wrongly prioritises emotional appeal over logical relevance.

Option C:
Option C is incorrect because it wrongly treats D and E as wrong alongside B, even though D and E accurately characterise what counts as strong and how both supporting and opposing arguments are evaluated in NET exams.

Option D:
Option D is correct since it identifies B and C together as the problematic statements, while leaving A, D and E recognised as accurate descriptions of how statement–argument items work.
