The Luddite movement in the Industrial Revolution was an example of which reaction?

Correct answer: Workers' protest against job threats from machines

The direct answer is B: workers' protest against the threat machines posed to jobs. The Luddite movement appeared in early nineteenth-century Britain during industrialisation. Skilled workers feared that some factories would use machines and less-skilled labour to reduce wages, weaken traditional skills, or remove their employment. The reasoning is: new machines changed production; some workers felt their jobs and earnings were threatened; groups called Luddites attacked or destroyed certain machines as a form of protest; the movement expressed labour unrest and insecurity. Option B is correct because it directly describes that reaction. Option A is wrong because Luddites did not seek the complete abolition of Parliament. Option C is wrong because the movement was not a campaign to expand slavery. Option D is wrong because Japanese Shogunate power belonged to a different country and historical context. The Luddites were not simply opposed to every form of technology; their protests focused on the harmful way machines were being used against workers' livelihoods and bargaining power. Memory cue: Luddite means machine-related worker protest, especially over jobs and skills.
