Explanation
Pair (a) is correctly matched: William Kennedy Dickson, a Scottish inventor working under the guidance of Thomas Edison, played a crucial role in the development of early motion picture technology. Pair (b) is correctly matched: Charles Babbage, an English mathematician, philosopher, and mechanical engineer, is widely regarded as the "father of the computer." He conceived the idea of a programmable mechanical computer, known as the Analytical Engine, in the 19th century. Babbage’s visionary work paved the way for the development of modern computing. Pair (c) is incorrectly matched: Nicholas Stern, Baron Stern of Brentford, is a British economist renowned for his work on the economics of climate change. His influential report, the Stern Review, published in 2006, highlighted the economic costs of inaction on climate change and emphasized the need for urgent global action. Stern’s work has been instrumental in raising awareness of the economic dimensions of climate change and has influenced policy decisions around the world. He is not associated with construction technology. Pair (d) is correctly matched: Brian Greene is a theoretical physicist and a prominent popularizer of string theory, a theoretical framework in physics that seeks to unify all the fundamental forces of nature. Greene is known for his ability to explain complex scientific concepts in an accessible way to a wider audience through his books, television appearances, and public lectures.
