Social Science (087) — AI-generated practice question

Before refrigerated ships, live animals were shipped from America to Europe and slaughtered on arrival. Many died or fell ill during the voyage, making meat expensive and a luxury beyond the reach of the poor.

Refrigerated ships allowed animals to be slaughtered at the source (America, Australia, New Zealand) and transported as frozen meat. This reduced shipping costs and lowered meat prices in Europe. As a result, ordinary Europeans could now afford a more varied diet, adding meat, butter, and eggs to their earlier monotonous diet of bread and potatoes. Better living conditions also promoted social peace.

• The answer addresses both parts: the change in practice AND the economic consequences.
• Key cause-effect chain: refrigeration → animals slaughtered at source → lower shipping costs → cheaper meat → better diet for the European poor.
• The phrase "social peace within the country" from the passage is worth including as it shows broader consequences.
• Avoid writing more than this — 3 marks = ~70–80 words is ideal.
