Q.2i) Trade unions were formed by labourers to get their rights. ii) Germany's political setup was the most significant challenge for the Industrial Revolution. iii) To protect capitalists Karl Marx advocated socialism. iv) There were no natural resources in Germany. Choose the correct option:v
  1. a. (i) is correct
  2. b. (ii) and (iii) are correct
  3. c. (i) and (iv) are correct
  4. d. (iii) is correct
Solution

Statement (i) is correct — trade unions were formed by workers to demand rights.

6V. Answer the following questions briefly6 questions
Q.1What was the condition of labourers' houses during Industrial Revolution?v
Solution

Labourers' housing was typically cramped and overcrowded (often one-room or back-to-back houses), poorly constructed, lacked basic sanitation and drainage, was damp and poorly ventilated, and contributed to frequent disease and high mortality.

Answer:

Overcrowded, poorly built, unsanitary and damp dwellings with little ventilation or sewage facilities.

Q.2Account for urbanisation in England.v
Solution

Points: 1) Factories and employment opportunities in towns attracted rural migrants. 2) Enclosure movement reduced small farmers' livelihoods, forcing migration. 3) Population increase increased urban labour supply. 4) Improved transport and infrastructure made cities accessible and supported industry and trade.

Answer:

Industrialisation created factory jobs that drew people from rural areas; enclosing of common lands displaced agricultural workers; population growth and improved transport (canals, railways) facilitated migration to towns; concentration of capital and services in urban centres accelerated city growth.

Q.2i) Trade unions were formed by labourers to get their rights. ii) Germany's political setup was the most significant challenge for the Industrial Revolution. iii) To protect capitalists Karl Marx advocated socialism. iv) There were no natural resources in Germany. Find out the correct option.v
  1. a. (i) is correct
  2. b. (ii) and (iii) are correct
  3. c. (i) and (iv) are correct
  4. d. iii) is correct
Solution

Same reasoning as earlier: (i) true. (ii) is imprecise; (iii) false — Marx opposed capitalism and advocated socialism to protect workers; (iv) false — Germany had coal and iron. Thus option (a) is the only unambiguously correct choice.

Answer:

a

Q.3Attempt a note on Haymarket Massacre.v
Solution

Brief points: 1) Took place in Haymarket Square, Chicago, during 1886 labour demonstrations. 2) Bomb explosion and police firing led to deaths and arrests. 3) Resulted in trials and executions of labour activists, and galvanized workers' rights movements worldwide.

Answer:

Haymarket Massacre (Chicago, 4 May 1886): During a labour rally for an eight-hour workday a bomb was thrown at police who were dispersing the crowd; several police and civilians died. Leaders (many anarchists) were arrested; the event became a symbol of the labour movement and influenced international labour activism (May Day).

7VI. Answer in Detail6 questions
Q.1Enumerate the causes for the Second Industrialization in the USA.v
Solution

Key causes:
- Abundant natural resources (coal, iron ore, oil) and vast land.
- Rapid expansion of railroads connecting markets and raw materials.
- Technological inventions and processes (Bessemer steel, electricity, telegraph, telephone, internal combustion engine).
- Growth of large domestic market and urbanisation increasing demand.
- Availability of capital and investment in industry.
- Large immigrant labour supply and skilled workforce.
- Supportive government policies (tariffs, land grants) and business organisation (corporations, trusts).
These factors together accelerated the USA's 'Second Industrial Revolution'.

Answer:

Causes included abundant natural resources, rapid expansion of railways, technological innovations (Bessemer steel, electricity, internal combustion), large domestic market, capital investment, immigration and labour supply, and pro‑industry government policies.

Q.2What were the effects of Industrial Revolution of England on India?v
Solution

Key impacts: 1) Economic dislocation: machine-made British goods undermined Indian artisans. 2) Colonial economic restructuring: India exported raw materials and imported finished goods. 3) Infrastructure: railways/roads built for British trade but modernised transport. 4) Social consequences: rural distress, famines, urban migration. 5) Political/long-term: growth of nationalist sentiment and modern institutions.

Answer:

Major effects included deindustrialisation of Indian handicrafts (especially textiles) due to cheap machine-made imports from England; India became a supplier of raw materials (cotton) and a market for British manufactured goods; decline in traditional industries and artisans’ livelihoods; introduction of railways, telegraph and modern infrastructure serving colonial interests; commercialization of agriculture, cash-crop cultivation and famines; economic drain of wealth to Britain; but also the rise of modern education, administrative reforms and new Indian entrepreneurs and nationalist responses.

Q.3Assertion (A): Workers had rights to get holidays. Reason (R): There were laws to protect the workers. Choose the correct option:v
  1. a. A is correct R is wrong
  2. b. Both A & R are wrong
  3. c. Both A and R are correct
  4. d. A is correct R is not correct explanation of A
Solution

A is incorrect for the early Industrial Revolution period — workers generally did not have rights to holidays. R is correct in that some labour-protective laws (e.g. early Factory Acts) were enacted, but these were limited and did not guarantee holiday rights initially. Hence both statements as given are not correct together.

Answer:

b

Q.3Assertion (A): Workers had rights to get holidays. Reason (R): There were laws to protect the workers.v
  1. a. A is correct R is wrong
  2. b. Both A & R are wrong
  3. c. Both A and R are correct
  4. d. A is correct R is not correct explanation of A
Solution

Same as previous: early workers generally lacked enforced rights to holidays (A false). Some protective laws existed but were limited (R cannot make A true). Therefore 'Both A & R are wrong' fits the assertion structure.

Answer:

b
