The combined power is 4 D + (-2 D) = 2 D (positive, so converging). Focal length = 1/Power = 1/2 = 0.5 m = 50 cm. A positive power means converging lens. The diopter (D) unit is the reciprocal of focal length in meters.

The Supreme Court of India originally had a sanctioned strength of 26 judges including the Chief Justice.

Golda Meir became Israel's PM in 1969, Indira Gandhi became India's PM in 1966, and Mary Eugenia Charles served as Dominica's PM from 1980-1995. None of these predated Sirimavo Bandaranaike's historic achievement.

This decisive battle established Babur's supremacy over northern India after his earlier victory at Panipat. Rana Sanga was defeated despite assembling a large Rajput confederacy.

Diamond is a crystalline form of pure carbon, making it an element. It consists entirely of carbon atoms arranged in a tetrahedral lattice structure. Diamond is not a compound (which requires two or more different elements chemically bonded), not a metal, and not a mixture of any kind.

Hungary is a landlocked country in Central Europe, meaning it has no direct access to the sea or ocean. Bulgaria and Romania have coastlines on the Black Sea, while Ukraine has coastline on both the Black Sea and the Sea of Azov.

NABARD (National Bank for Agriculture and Rural Development) provides refinance to Scheduled Commercial Banks, Regional Rural Banks, and State Land Development Banks to support agriculture and rural development. However, Export-Import Bank (Exim Bank) is a specialized financial institution for foreign trade promotion and does not fall under NABARD's refinance ambit, which is focused on domestic rural and agricultural sectors.

Linoleic acid (an omega-6 fatty acid) is an essential fatty acid that the human body cannot synthesize and must obtain from dietary sources. It is crucial for various physiological functions including cell membrane structure and production of signaling molecules. Butyric acid, oleic acid, and stearic acid can all be synthesized by the human body and are not essential in the diet.

Atmospheric pressure decreases with increasing altitude. Mumbai (option 3) is at sea level, Delhi (option 4) is around 216 meters, Shimla (option 1) is about 2,276 meters, and Gangtok (option 2) is approximately 1,650 meters. Therefore, the correct decreasing order of atmospheric pressure is Mumbai > Delhi > Shimla > Gangtok, which matches option 3-4-1-2.

Aldol condensation requires compounds with alpha-hydrogens. Aldehydes (option A) and ketones (option B) have alpha-hydrogens and can undergo aldol condensation. An aldehyde and ketone combination (option C) can also undergo aldol condensation. However, esters (option D) generally do not have acidic alpha-hydrogens in the same way and cannot participate in classic aldol condensation reactions under normal conditions.

The Central Institute of Fisheries Technology (CIFT) is located in Kochi, Kerala (option C). Kochi and Ernakulam are twin cities, but CIFT is specifically situated in the Kochi area. It is a premier research institution under the Indian Council of Agricultural Research (ICAR) focusing on fishing technology and processing.

The number of molecules in a given mass is inversely proportional to the molar mass. Hydrogen (H2) has the lowest molar mass (2 g/mol), so 1 gram of hydrogen contains the most molecules (0.5 moles). Carbon dioxide (44 g/mol), oxygen (32 g/mol), and ammonia (17 g/mol) all have higher molar masses, meaning the same mass contains fewer molecules. For example, 10g CO2 is only 0.23 moles.

The Earth's axial tilt (approximately 23.5 degrees) is the primary reason for seasons. Without this tilt, the amount and intensity of sunlight received at different latitudes would remain constant throughout the year, resulting in no seasonal changes. Option A is incorrect because seasons would not exist at all, let alone have the same duration. Options C and D are incorrect because there would be no distinct summer or winter periods.

Amil was the administrative head of a Paragana in the Delhi Sultanate. The Paragana was the basic fiscal and administrative unit, and the Amil was responsible for revenue collection and maintaining law and order in that jurisdiction.

Trent and Westside are both retail chains promoted by the Tata group. Trent runs the Westside retail stores, which sell clothing, footwear, and accessories. The Tata group is one of India's largest business conglomerates with diverse interests including retail through these chains.

In an ideal resistor, voltage and current are always in phase because resistors follow Ohm's Law (V = IR) without any phase shift. In an ideal capacitor, current leads voltage by 90 degrees. In an ideal coil (inductor), voltage leads current by 90 degrees. An ideal transformer has phase relationships between its primary and secondary windings.

All three statements about Parkinson's disease are correct. Statement I gives accurate epidemiological statistics for Britain. Statement II correctly states that Parkinson's is caused by loss of dopamine-producing nerve cells in the substantia nigra region of the brain. Statement III correctly describes the role of dopamine in transmitting messages to coordinate movement.

All three statements about the Morley-Minto Reform Act (1909) are correct. Statement 1 is accurate - it increased the number of additional members in the Central Legislature. Statement 2 is correct - it introduced communal representation through separate electorates for Muslims. Statement 3 is also correct - it granted limited powers to legislators to discuss the budget and move resolutions, though executive authority remained with the British.

The Subsidiary Alliance System, introduced by Lord Wellesley, had specific features: a subsidiary British army was maintained in the Indian state (Option A - correct feature), the Indian state paid for this army (Option B - correct feature), and a British Resident was kept at the capital (Option C - correct feature). However, Indian soldiers could NOT be used by Company commanders (Option D - this was NOT a feature; in fact, the system aimed to reduce military power of Indian states).

The Chief Election Commissioner of India can be removed from office through the same impeachment process as a Supreme Court judge - by a two-thirds majority of Parliament membership on grounds of 'proved misbehavior or incapacity.' This ensures the CEC has security of tenure and independence similar to constitutional court judges. The CAG has similar removal provisions, while the Attorney-General and High Court judges have different removal procedures.

Statement D is not correct because the survey being referenced (Britain's league table of world universities) does not cover 50 countries - it covers many more countries worldwide. The other statements accurately reflect the state of higher education rankings where no Indian university featured in the top 200, while China had six universities in the list, and other Asian nations like Japan, Singapore, Hong Kong, Taiwan, and South Korea had world-class institutions.
