**Background Information:**
Aurangzeb was the sixth Mughal emperor of India, ruling from 1658 to 1707. He was known for his strict and orthodox interpretation of Islam, which led to several policies that aimed to limit the influence of non-Muslims in the empire.

**Explanation:**
The correct answer is option 'A' - Aurangzeb banned the playing of pungi in the royal palace because he did not like its unpleasant tone. Here is an explanation of this answer:

**1. The Nature of the Pungi Instrument:**
The pungi is a wind instrument commonly associated with snake charmers in India. It consists of a wooden reed attached to a gourd, which is blown into to produce sound. The tone of the pungi is often described as unpleasant and shrill.

**2. Aurangzeb's Personal Preference:**
Aurangzeb, known for his austere and strict personality, had a dislike for music and other forms of entertainment. He considered them distractions from religious devotion and believed that they led to moral decadence. Therefore, it is likely that the unpleasant tone of the pungi was in direct conflict with Aurangzeb's personal taste and preference for simplicity.

**3. Ban on Music in the Royal Palace:**
Aurangzeb implemented strict regulations against music and other forms of entertainment during his reign. He believed that indulging in such activities went against the principles of Islam and undermined the moral fabric of the empire. As a result, he prohibited the playing of musical instruments, including the pungi, in the royal palace.

**4. Suppression of Hindu Culture:**
While it is true that Aurangzeb had a strained relationship with the Hindu population of the empire and implemented policies that favored Islam, the ban on pungi cannot be solely attributed to religious discrimination. Aurangzeb's disapproval of music was not limited to a specific religion but rather stemmed from his personal beliefs and strict interpretation of Islam.

**Conclusion:**
In conclusion, Aurangzeb banned the playing of pungi in the royal palace because he did not like its unpleasant tone. This ban was part of his broader restrictions on music and entertainment, which he believed went against Islamic principles and moral values. While Aurangzeb's policies did have a significant impact on the Hindu population, the ban on pungi cannot be solely attributed to religious discrimination but rather to his personal preferences and beliefs.

- To determine the answer, we need to analyze the given options and select the one that is most appropriate.
- Let's analyze each option one by one:

a) professional barbers:
- It is possible for a barber to belong to a family of professional barbers.
- However, the question specifies that the barber belongs to a particular family, not a profession.
- Therefore, this option does not provide a satisfactory answer.

- It is possible for someone to have a family background in music, and being a barber could be their personal profession.
- Therefore, this option is a suitable answer.

c) professional soldiers:
- This option suggests that the barber belongs to a family of professional soldiers.
- While it is possible for someone to have a family background in the military, being a barber is not directly related to the profession of a soldier.
- Therefore, this option is less likely to be the correct answer.

- This option suggests that the barber belongs to a family of professional beggars.
- Being a barber is a profession that requires skills and training, and it is unlikely for a barber to come from a family of professional beggars.

Reasons for the Russian Revolution of 1905:

Introduction:
The Russian Revolution of 1905 was a major uprising that took place in Russia during the reign of Tsar Nicholas II. It was a significant event in Russian history and a precursor to the larger revolution that would occur in 1917. The revolution was sparked by a range of factors, but the primary reason can be attributed to the Czar's refusal to allow Russia to industrialize.

1. Political Repression and Economic Inequality:
- The Russian Empire was characterized by a rigid social hierarchy and political repression. The majority of the population, particularly the peasants and workers, faced extreme poverty and inequality.
- The government was autocratic, with Tsar Nicholas II holding absolute power. The lack of political representation and civil liberties led to growing discontent among the people.

2. Economic Conditions and Workers' Strikes:
- Industrialization was slow in Russia, leading to poor working conditions and low wages for factory workers. The working class faced exploitation and long hours without any social or economic protections.
- Workers began organizing strikes and demanding better conditions, higher wages, and the right to form trade unions. These strikes spread across the country, causing disruptions to the economy and further fueling the revolutionary sentiment.

3. Bloody Sunday and the Massacre:
- On January 9, 1905, a peaceful protest led by Father Georgy Gapon was organized in St. Petersburg, with thousands of workers and their families participating. They marched to the Winter Palace to present a petition to the Tsar, calling for improved working conditions and political reforms.
- However, the Tsar's forces opened fire on the protesters, resulting in hundreds of deaths and injuries. This event, known as Bloody Sunday, served as a catalyst for the revolution and further intensified the anger and resentment towards the autocratic regime.

4. Rise of Political Opposition:
- The revolution saw the emergence of various political groups and organizations advocating for change. These included liberal parties, socialists, and revolutionary movements such as the Bolsheviks and Mensheviks.
- These groups sought to overthrow the autocracy and establish a more democratic and egalitarian society. They gained support from various sections of society, including workers, peasants, and intellectuals.

Conclusion:
While there were other contributing factors to the Russian Revolution of 1905, such as Russia's defeat in the Russo-Japanese War and the influence of revolutionary ideas from abroad, the primary reason was the Czar's refusal to allow Russia to industrialize. This led to immense discontent among the population, resulting in widespread protests, strikes, and ultimately, the revolution. The events of 1905 set the stage for the larger revolution that would occur in 1917, ultimately leading to the overthrow of the Tsarist regime and the establishment of a communist government under Lenin.

Carbon disulfide evaporates at room temperature, and the vapour is more than twice as heavy as air. It easily explodes in the air and also catches fire very easily.

The answer to the given question is option 'c) Third'.

Explanation:

The Third Estate was the least prosperous estate in France during the 18th century. Here is a detailed explanation of why the Third Estate faced economic hardships compared to the other two estates:

1. Introduction:
- The French society was divided into three estates: the First Estate (clergy), the Second Estate (nobility), and the Third Estate (commoners).

2. Economic Imbalance:
- The First and Second Estates enjoyed numerous privileges, including exemption from taxes.
- The burden of taxation fell mainly on the Third Estate, leading to economic inequality.

3. Taxation:
- The Third Estate had to pay a variety of taxes, including the taille (land tax), the gabelle (salt tax), and the tithe (church tax).
- These taxes were often oppressive and imposed a heavy financial burden on the common people.

4. Economic Activities:
- The Third Estate primarily consisted of peasants, laborers, and urban workers.
- Peasants were heavily taxed and had to provide labor services to the nobles.
- Urban workers faced low wages, long working hours, and poor working conditions.

5. Lack of Representation:
- The Third Estate had limited representation in the Estates-General, the legislative body of France.
- Despite comprising the majority of the population, their voices and demands were often ignored by the privileged estates.

6. Financial Crisis:
- The extravagant lifestyle of the nobility and the monarchy, coupled with costly wars, led to a severe financial crisis in France.
- To address the crisis, the monarchy attempted to impose further taxes on the Third Estate, exacerbating their economic hardships.

7. Causes of the French Revolution:
- The economic grievances faced by the Third Estate played a significant role in triggering the French Revolution of 1789.
- The commoners demanded political and social reforms, equal rights, and a fairer distribution of wealth.

In conclusion, the Third Estate was the least prosperous estate in France due to heavy taxation, economic hardships faced by peasants and urban workers, and lack of representation. These factors contributed to the growing discontent that eventually led to the French Revolution.
