The oxidation number of manganese (Mn) in potassium permanganate (KMnO₄) is:
सही उत्तर: ख) +3
In KMnO₄, Potassium (K) has a +1 charge. Oxygen usually has a -2 charge. Let 'x' be the oxidation number of Mn. The equation is: +1 + x + 4(-2) = 0, which simplifies to x = +7. This is the standard approach to determining oxidation numbers in compounds. The other options are incorrect based on the established rules for assigning oxidation states.

The solubility of a gas in water is directly proportional to which factor?
सही उत्तर: क) Pressure
According to Henry's Law, the partial pressure of a gas above a liquid is directly proportional to the concentration of that gas dissolved in the liquid. Therefore, increasing the pressure will increase the solubility (concentration). The other options are irrelevant to Henry’s Law.

A chemical reaction proceeds with a rate constant k = 2.3 x 10⁻³ s⁻¹. What is the half-life of this reaction?
सही उत्तर: क) 106.9 seconds
This is a first-order reaction, and the half-life (t₁/₂) for a first-order reaction is related to the rate constant by the equation t₁/₂ = 0.693/k. Calculating 0.693 / 2.3 x 10⁻³ s⁻¹ gives approximately 30 seconds, closest to 34.6 seconds. The other options are far from the correct value.

Identify the sentence that demonstrates correct usage of subject-verb agreement:
सही उत्तर: क) The sheep is grazing peacefully in the meadow.
Subject-verb agreement dictates that singular subjects take singular verbs and plural subjects take plural verbs. ‘Sheep’ is a collective noun referring to multiple animals, so it requires the plural verb ‘are’. Options B and C are incorrect because they use 'are' and 'were' incorrectly for a singular subject. Option D incorrectly uses the present tense as a continuous action.

Choose the correct synonym for the word 'prolific' in the context of agriculture:
सही उत्तर: ख) Productive
’Prolific’ means producing abundantly, which aligns perfectly with ‘productive’. ‘Scarce’ denotes a lack of something, while ‘infertile’ describes something incapable of producing and 'limited' indicates restriction. This choice correctly captures the meaning within an agricultural setting.

Select the sentence with the most appropriate use of vocabulary: ‘The farmer utilized advanced irrigation techniques to enhance crop yield.’
सही उत्तर: ग) The farmer utilized innovative water management strategies for better food output.
Using ‘utilized’ and ‘enhance crop yield’ demonstrates a more sophisticated understanding of agricultural terminology than the other options, which employ simpler or less precise language regarding irrigation and production. Options A and D are simplistic, while option B has some inaccuracies.

The following sentence is grammatically incorrect: ‘He has been reading books since last week.’ Which of the following revisions makes the sentence correct?
सही उत्तर: क) He had been reading books since last week.
The original sentence uses ‘since’ incorrectly to denote an action that began in the past and continues to the present. The correct usage is ‘had been reading,’ which accurately reflects this continuous past action. Option B is incorrect because it uses ‘is reading’, indicating a current ongoing activity, which doesn’t align with the passage of time implied by ‘since.’
