After the Corn Laws were abolished, cheap food imports made British agriculture uncompetitive. Vast areas of land were left uncultivated and thousands of agricultural workers lost their jobs. They migrated to cities or overseas. To meet Britain's rising food demand, lands were cleared in America and Australia and food production expanded. Railways, ports, and settlements were needed, requiring capital and labour. Since labour was scarce in America and Australia, large-scale migration from Europe was encouraged. Nearly 50 million people emigrated from Europe to America and Australia in the nineteenth century.

The examiner expects a clear chain/sequence of causes and effects: Corn Laws abolished → cheap imports → British agriculture collapses → unemployment → migration from Britain + demand for food overseas → land clearance in America/Australia → need for labour → large-scale European migration. Use connecting words like "therefore," "as a result," "this led to" to show the chain. The figure "50 million emigrants" is a good fact to include.
