High levels of nitrate in drinking water can cause ‘blue baby syndrome’, which is: (a) Excessive iron absorption (b) Methemoglobinemia (c) Cyanide poisoning (d) Lead toxicity
सही उत्तर: ख) (b) Methemoglobinemia
Methemoglobinemia (option b) is the correct answer. Nitrate in drinking water converts to nitrite which then reacts with hemoglobin to form methemoglobin, reducing the oxygen-carrying capacity of blood. The tempting option ‘excessive iron absorption’ is incorrect as it relates to hemosiderosis and does not explain the blue discoloration.

What specific factor contributes most significantly to the vulnerability of rice crops cultivated on Nepal’s southern slopes to disease outbreaks?

In terms of agricultural planning in Nepal, what does ‘mixed cropping’ primarily aim to achieve?

Considering Nepal’s forestry practices, what is the main rationale behind ‘slash and burn’ (Chipko) agriculture?
सही उत्तर: ग) Utilizing nutrient-poor soils for temporary crop production
Slash and burn agriculture, commonly known as Chipko, involves clearing a patch of land by cutting down trees and burning the vegetation. This releases nutrients into the soil, which are then temporarily utilized for cultivating crops before the land is left fallow – a sustainable practice given Nepal’s often poor soils. The other options represent unsustainable forestry practices.

The ‘Jhapri’ soil type, prevalent in parts of Nepal's Terai region, is characterized by what key feature?
सही उत्तर: ग) Reddish color due to iron oxides and high lime content
Jhapri soils are renowned for their distinctive dark-colored, clay-rich composition, which results from the accumulation of decayed vegetation. This creates a poorly aerated soil with slow drainage - making it less suitable for many crops. The other options describe different soil types.

Ketones do not exhibit this reaction. This question tests knowledge of specific chemical tests and functional group properties.
