Q3177. Identify the correct pair distinguishing between a breach of privilege and contempt of the House.

A breach of privilege specifically refers to the violation of the established rights and immunities of individual members or the House. In contrast, contempt of the House is a broader concept.

Understanding this distinction is vital for interpreting how Parliament protects its institutional integrity.
Q3178. What is considered the most critical, direct benefit of implementing the Soil Health Card scheme on a nationwide scale?
Explanation
The most critical and direct benefit of the Soil Health Card scheme is its role in promoting the balanced and scientific use of chemical fertilizers. By identifying exact nutrient deficiencies in the soil, the card discourages the traditional practice of indiscriminate fertilizer application. This leads to healthier soil, improved crop yields, and reduced environmental pollution from excessive chemical runoff.
