AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The Spinning Jenny, invented by James Hargreaves, could do the work of many spinners at once, greatly speeding up the spinning process. Women who depended on hand spinning for their livelihood feared that the machine would take away their jobs and reduce their earnings. This threat to their employment caused them to attack and destroy the machines.
The examiner expects you to link the cause (fear of unemployment/loss of livelihood) directly to the effect (women attacking the machines). Two marks = two clear points: (1) the Jenny replaced many hand spinners, (2) women feared losing their income and so attacked it. Keep it concise — no need to describe how the Jenny worked in detail.
