Correct Answer: b) Opium

Explanation: The triangular trade between India, China, and England during the 18th and 19th centuries was primarily based on opium. Here’s how it worked:

1. India to China: The British East India Company cultivated opium in India (mainly in Bengal and Bihar) and exported it to China. Opium was in high demand in China, despite the Chinese government’s attempts to ban its trade due to its harmful effects on society.

2. China to England: The British used the profits from the opium trade to purchase Chinese goods like tea, silk, and porcelain, which were highly sought after in England.

3. England to India: The British exported manufactured goods from England to India, completing the triangular trade.

This system was highly exploitative and led to significant social and economic consequences, including the infamous Opium Wars between Britain and China. While commodities like silk and black pepper were also traded, opium was the chief economic foundation of this triangular commerce.

The correct answer is: c) Jamui

Explanation:

Shreyasi Singh, a Member of the Legislative Assembly (MLA) from Bihar, was elected from the Jamui constituency. She won her seat in the 2020 Bihar Assembly elections as a candidate from the Bharatiya Janata Party (BJP), defeating the incumbent MLA by a significant margin.

Correct Answer: b) Fodder

Explanation:

Zaid crops are those crops that are grown in the short season between the Rabi and Kharif seasons, typically from March to June. These crops require warm, dry weather for growth and a longer day length for flowering.

– Fodder is considered a zaid crop as it is grown during this short season to provide feed for livestock.

– Gram is a Rabi crop, grown in the winter season.

– Mustard is also a Rabi crop, cultivated during the winter months.

– Cotton is a Kharif crop, grown during the monsoon season.

Thus, the correct answer is Fodder, as it fits the characteristics of a zaid crop.

The correct answer is: d) Sub-Inspector of Police

Explanation:

Manvi Madhu Kashyap recently became Bihar’s first transgender Sub-Inspector of Police. This historic achievement marks a significant milestone not only for her but also for the transgender community in India, as she is one of the few to achieve this rank in the state police force.

The correct answer is: a) Financial Year 2020-21

Explanation:

Bihar State introduced its Green Budget for the first time in the Financial Year 2020-21. This initiative was officially tabled in the legislative assembly on March 15, 2020, making Bihar the first state in India to present a separate Green Budget aimed at integrating environmental considerations into government spending and promoting ecological sustainability.

Correct Answer: c) Neelam Sanjeeva Reddy

Explanation:

Neelam Sanjeeva Reddy was the only person among the given options who served as the Speaker of the Lok Sabha before being elected as the President of India. He was the 6th President of India, serving from 1977 to 1982. Prior to his presidency, he held various significant positions, including being the Speaker of the Lok Sabha from 1967 to 1969.

The other options do not fit:

– Giani Zail Singh: He was the 7th President of India (1982–1987) but never served as the Speaker of the Lok Sabha.

– V. V. Giri: He was the 4th President of India (1969–1974) and also did not serve as the Speaker of the Lok Sabha.

– A. P. J. Abdul Kalam: He was the 11th President of India (2002–2007) and was a renowned scientist, not involved in parliamentary roles like Speaker.

Thus, the correct answer is Neelam Sanjeeva Reddy.

Correct Answer: c) Nanda Vansh

Explanation:

The Shishunaga dynasty was succeeded by the Nanda dynasty in Magadha. The Nanda dynasty was established by Mahapadma Nanda, who is often considered the first ruler of this dynasty. The Nandas were known for their vast wealth and powerful army, which played a significant role in the history of ancient India.

The Maurya dynasty (option a) came after the Nanda dynasty, with Chandragupta Maurya overthrowing the last Nanda ruler, Dhana Nanda, to establish the Mauryan Empire. The Sunga dynasty (option b) came much later, after the fall of the Mauryan Empire.

Thus, the correct answer is c) Nanda Vansh.

Correct Answer: d) Newton per ampere meter

Explanation:

The tesla (T) is the SI unit of magnetic flux density (or magnetic field strength). It is defined as the magnetic flux density that produces a force of one newton (N) on a one-meter-long conductor carrying a current of one ampere (A) perpendicular to the magnetic field.

From the Lorentz force law, the force F on a current-carrying conductor in a magnetic field is given by:

F = B · I · L · sinθ

Where:

– F is the force in newtons (N),

– B is the magnetic flux density in teslas (T),

– I is the current in amperes (A),

– L is the length of the conductor in meters (m),

– θ is the angle between the conductor and the magnetic field.

Rearranging for B, when sinθ = 1 (perpendicular field):

B = F / (I · L)

The unit of B (tesla) can thus be expressed as:

1 T = N / (A · m)

This matches option d) Newton per ampere meter.

Correct Answer: a) Raiyati Sarkar – Kheda (Gujarat)

Explanation:

2. Prati Sarkar – Satara (Maharashtra): This is correct. The “Prati Sarkar” (Parallel Government) was established in Satara, Maharashtra, under the leadership of Nana Patil and others. It was one of the most prominent examples of a parallel government during the Quit India Movement.

3. Praja Mandal – Talcher (Orissa): This is correct. The Praja Mandal movement in Talcher (Odisha) was part of the Quit India Movement, where local leaders organized resistance against British rule and princely states.

4. Jatiya Sarkar – Tamluk (Bengal): This is correct. The “Jatiya Sarkar” (National Government) was established in Tamluk, Bengal, during the Quit India Movement. It was a well-organized parallel government that undertook various administrative functions.

Conclusion: The incorrect match is a) Raiyati Sarkar – Kheda (Gujarat).

Correct Answer: b) Quit India

Explanation:

The political strategy of “Struggle-Truce-Struggle” (S-T-S) was a concept used by Mahatma Gandhi during the Indian freedom struggle. It referred to a cyclical approach where periods of active resistance (struggle) were followed by temporary truces or negotiations, and then resumed with renewed vigor if the goals were not achieved.

This strategy came into prominence during the Quit India Movement of 1942. The Quit India Movement was a mass civil disobedience campaign launched by the Indian National Congress under Gandhi’s leadership, demanding an end to British rule in India. The S-T-S approach was evident as Gandhi believed in alternating between phases of intense struggle and temporary pauses to reassess and strategize.

The other options are incorrect because:

– a) Swadeshi Movement: This was primarily focused on promoting indigenous goods and boycotting British products, not directly linked to the S-T-S strategy.

– c) Boycott of Simon Commission: This was a specific protest against the Simon Commission in 1928, not associated with the S-T-S framework.

– d) Khilafat issue: This was a movement to support the Ottoman Caliphate and had no direct connection to the S-T-S strategy.

Thus, the correct answer is b) Quit India.
