The Age of Social Change

The Cold War was a prolonged political, ideological, military and economic rivalry between the United States and the Soviet Union after the Second World War. The two superpowers generally avoided direct full-scale war with each other but competed through alliances, arms development, propaganda and proxy conflicts. Other countries had regional tensions, but they were not the principal Cold War rivals. Hence A is correct.

Capitalism is an economic system in which private ownership of property and productive resources, market exchange, competition and the possibility of profit play central roles. Governments may regulate capitalist economies, so it does not mean the complete absence of state action. Complete state control is more closely associated with centrally planned systems, while feudal loyalty and slave labour describe different historical arrangements. Thus A is best.

Socialism is a broad family of ideas that emphasises reducing economic inequality, protecting workers and organising important resources or production in the public or collective interest. Different socialist theories vary in how much ownership should be public and how markets should operate. It is therefore not the same as monarchy, slave trade or a system focused only on private profit. Option A expresses the central idea.

The factory system concentrated machines, raw materials and workers in a single workplace. It increased the scale and speed of production and shifted much manufacturing away from dispersed household handwork toward machine-based production. This change also encouraged wage labour, industrial discipline and urban growth. The other options describe no major feature of the Industrial Revolution, so the movement from hand production to machine production is correct.

Industrialization created factories that were concentrated mainly in towns and cities. Many people left villages or moved between regions to seek wage employment, causing urban populations to grow rapidly. Cities also developed new housing, transport and class relations, often under difficult conditions. This process is called urbanization. It did not produce a general return to forest or nomadic life, so option A is correct.

Karl Marx analyzed capitalism, class relations and the exploitation of wage labour. With Friedrich Engels, he argued that historical change was strongly shaped by class struggle and proposed a society in which production would not be controlled by a private ruling class. His ideas became highly influential in socialist and communist movements, though later groups interpreted them differently. Thus socialism and communism are the correct association.

The Communist Manifesto was written by Karl Marx and Friedrich Engels and published in 1848. It presents a brief argument about history, class conflict and the political aims of communists, including the importance of workers organizing against exploitation. It is not a scientific work by Galileo and Newton or a travel account by Columbus and Vasco da Gama. Therefore Marx and Engels are the correct authors.

Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated at Sarajevo on 28 June 1914. Austria-Hungary then declared war on Serbia, and alliance commitments widened the conflict into the First World War. Nationalism, militarism, imperial rivalry and competing alliances had already created deep tensions, so the assassination was the immediate trigger rather than the sole underlying cause. Hence A is correct.

The First World War lasted from 1914 to 1918. Germany and the Central Powers were defeated, and the armistice on 11 November 1918 ended the main fighting on the Western Front. Formal peace settlements, including the Treaty of Versailles in 1919, followed afterward. Therefore 1918 is the correct end year; 1939 marks the beginning of the Second World War and 1945 its end.

The League of Nations was established after the First World War to promote international cooperation, settle disputes peacefully and prevent another major war. It was an early attempt at collective security, although it lacked strong enforcement powers and ultimately failed to stop aggression in the 1930s. Its purpose was not industrial management, revolution-making or colonial creation. Therefore maintaining world peace is the correct answer.

Leonardo da Vinci represented the Renaissance ideal of a many-sided individual. He was a painter of works such as the Mona Lisa and The Last Supper, while also studying anatomy, engineering, mathematics, and natural phenomena. His wide interests explain why both art and science are correct. The options limited to war, trade, or law do not describe his principal achievements.

Michelangelo was a leading Renaissance artist known especially for sculpture, painting, and architecture. His marble statue David and the ceiling frescoes of the Sistine Chapel are among his best-known works. He was not a military, tax, or railway specialist. Although he also worked in architecture and poetry, the combination of sculpture and painting best matches the choices.

Nicolaus Copernicus proposed a heliocentric model in which Earth and the other planets move around the Sun. This challenged the widely accepted Earth-centered model and became an important foundation of the Scientific Revolution. Democracy, class struggle, and divine right are political or social ideas associated with other thinkers and historical contexts, not Copernicus’s central contribution.

Galileo used an improved telescope to observe the sky and reported important evidence, including mountains on the Moon, the phases of Venus, and moons orbiting Jupiter. These observations challenged some traditional ideas about the heavens. A microscope magnifies very small objects, a compass helps with direction, and a clock measures time, so the telescope is correct.

Isaac Newton formulated the law of universal gravitation and the three laws of motion, transforming the study of mechanics. His work explained how bodies attract one another and helped establish classical physics. The law of heredity is associated with Mendel, natural selection with Darwin, and the law of demand with economics, so gravitation is the correct choice here.

The Spinning Jenny was a hand-powered spinning machine developed by James Hargreaves in the eighteenth century. It allowed one worker to spin several threads at once and greatly increased yarn production in the textile industry. It did not smelt iron, build ships, or manufacture paper. Its importance lies in speeding up cotton spinning and contributing to industrial textile production.

James Watt made important improvements to the steam engine, especially by developing a separate condenser that reduced wasted energy. These improvements made steam power more efficient and useful in factories, mines, and transport. Thomas Newcomen had developed an earlier practical engine, so Watt did not invent the steam engine from nothing. Darwin, Smith, and Galileo worked in other fields.

Adam Smith wrote An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. The book examined division of labour, exchange, markets, and the role of economic incentives, and it became highly influential in classical economics. Karl Marx wrote later works such as Capital, while Rousseau and Voltaire were mainly associated with Enlightenment political and philosophical writings.

The Communist Manifesto was written by Karl Marx and Friedrich Engels and published in 1848. It argues that history is shaped by class struggle and calls on workers to challenge the capitalist social order. Adam Smith and Newton belonged to different intellectual fields, Rousseau and Voltaire were Enlightenment thinkers, and Lincoln and Washington were American political leaders, so option A is unambiguous.

The French Revolution showed the possibility of change. In exams link it with the rise of new political ideas.
