Question

the discovery of the antikythera mechanism in 1900 revolutionized our understanding of ancient greek technology. found in a shipwreck off the greek island of antikythera, this complex device, consisting of at least 30 bronze gears, dates back to the 2nd century bce. research suggests it was used to calculate astronomical positions and predict eclipses. the antikythera mechanisms sophistication challenges long - held assumptions about the limitations of ancient science and engineering, demonstrating that the ancient greeks possessed advanced mechanical knowledge and skill. which choice best describes the function of the underlined sentence in the text as a whole? choose 1 answer: a it provides evidence to support the claim that the antikythera mechanism was used for astronomical calculations. b it highlights the significance of the discovery of the antikythera mechanism. c it introduces a counterargument to the prevailing theory about the purpose of the antikythera mechanism. d it suggests that the complexity of the antikythera mechanism was unique among ancient greek mechanical devices.

Explanation:

The text begins by stating that the discovery of the Antikythera mechanism revolutionized understanding of ancient Greek technology. The underlined sentence then elaborates on how its sophistication challenges assumptions about ancient science and engineering, which ties back to highlighting the significance of its discovery (as the first sentence introduced its revolutionary aspect). Option A is incorrect as the underlined sentence is more about the overall significance rather than just evidence for astronomical use. Option C is wrong as there's no counter - argument about its purpose. Option D is incorrect as there's no comparison to show it's unique among ancient Greek devices.

Answer:

B. It highlights the significance of the discovery of the Antikythera mechanism.
