Indian Polity and General Science

Article 108 of the Indian Constitution states that the President shall summon a joint sitting of both Houses to resolve disagreements on ordinary bills. The Speaker of Lok Sabha presides over such sessions, but only the President has the constitutional authority to summon them. This is a crucial provision for legislative deadlock resolution.

Article 58(1)(b) of the Indian Constitution states that a person must be not less than 35 years of age to be eligible for election as President. This age requirement ensures maturity and experience for the highest constitutional office. Options A (75 years upper limit), B (20 years), and D (18 years) are all incorrect.

Fundamental Rights serve as a check on the 'tyranny of the majority' by protecting individual and minority rights against democratic excesses. They are not absolute (reasonable restrictions can be imposed) and their primary purpose is to safeguard individual liberty and dignity. Option C correctly captures their role as constraints on majority power.

The Eighth Schedule originally had 14 languages, expanded to 18 in 1992, and currently has 22 languages (as of 2003 amendments). When this question was framed, the answer '18' was correct, making it a temporally accurate question. The Eighth Schedule lists languages recognized by the Indian Constitution for official purposes.

Article 109(5) states that the Rajya Sabha can delay a Money Bill passed by Lok Sabha for a maximum of 14 days. If Rajya Sabha does not return the bill within 14 days, it is deemed to have been passed by both Houses. This provision ensures that the directly elected Lok Sabha has primacy in financial matters.

The primary objective of Fundamental Rights is to ensure individual liberty by protecting citizens from arbitrary state action. While they support democratic government and judicial independence, their core purpose is safeguarding personal freedoms. Option B correctly identifies individual liberty as the central concern.

The 61st Constitutional Amendment Act, 1989 reduced the voting age from 21 years to 18 years. This expanded democratic participation by allowing younger citizens to vote in elections.

The President of India is elected by an electoral college consisting of elected members of Parliament and State Legislative Assemblies, not by the Council of Ministers. The Council's actual roles include policy formulation, inter-departmental coordination, and advisory functions for appointments.

Under Article 352, a proclamation of Emergency must be approved by both Houses of Parliament within one month. If approved, it lasts for six months unless revoked earlier. This ensures legislative oversight on executive emergency powers.

The 42nd Amendment (1976) added 'Socialist,' 'Secular,' and 'Integrity' to the Preamble. The existing words 'Sovereign,' 'Democratic,' and 'Republic' were retained. This amendment was controversial and later partially reviewed.

A transformer changes AC voltage levels through electromagnetic induction between primary and secondary coils. It cannot work with DC current. Dynamos generate electricity, conductors transmit current, and inductors oppose current changes.

Creating new states under Article 3 requires: Parliamentary law (4), President's recommendation and assent (3), and reference to the concerned state legislature for its view (2). The Supreme Court has no constitutional role (1) as this is a legislative, not judicial, function.

Bone marrow, specifically red marrow found in flat bones like sternum and pelvis, produces all blood cells through hematopoiesis. The heart pumps blood, spleen filters it, and kidneys filter waste: none produce blood cells.

Benzoic acid and its salts (sodium benzoate) are widely used preservatives in acidic foods, beverages, and processed items. They inhibit microbial growth effectively. Acetic acid (vinegar) also preserves but is more commonly used directly in pickling.

The Prime Minister is the leader of the majority party or coalition in the Lok Sabha, making them the head of government. This is why the PM appoints council of ministers and leads the executive branch.

Article 80(1)(a) of the Constitution authorizes the President to nominate 12 members to Rajya Sabha based on their expertise in literature, science, art, and social service. These nominated members bring specialist knowledge to the upper house.

Kelvin is the SI base unit for thermodynamic temperature, named after Lord Kelvin. While Celsius and Fahrenheit are commonly used scales, Kelvin is the scientific standard starting from absolute zero.

Under Article 108, a joint sitting of both Houses can be called by the President to resolve disagreements on ordinary bills (except money bills). Money bills originate only in Lok Sabha and Rajya Sabha cannot amend them, so joint sitting applies to other legislation.

Article 265 of the Constitution explicitly states no tax shall be levied or collected except by authority of law. The Seventh Schedule lists agricultural taxes as entries under State List, meaning state legislatures can impose them under constitutional authority.

Article 112 mandates that the President shall cause to be laid before both Houses an Annual Financial Statement (Budget) showing estimated receipts and expenditure. This constitutional requirement ensures fiscal transparency and accountability.
