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 mechanism’s 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:

• Option A: The underlined sentence is not about providing evidence for astronomical calculations (that was the prior sentence), so A is incorrect.
• Option B: The underlined sentence talks about how the mechanism's sophistication challenges old assumptions and shows advanced Greek knowledge, which emphasizes the importance of its discovery. This matches.
• Option C: There's no counterargument here; it's highlighting significance, not opposing a theory, so C is wrong.
• Option D: The sentence doesn't compare its complexity to other Greek devices, so D is incorrect.

Answer:

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