Recent archaeological findings suggest that many ancient civilizations, previously thought to be technologically unsophisticated, possessed knowledge of advanced astronomical phenomena. Intricate carvings aligning with specific celestial events, and structures precisely oriented towards solstices and equinoxes, indicate a sophisticated understanding of the cosmos. This implies that these societies were not merely primitive farmers or hunters but likely had specialized astronomers or priests dedicated to celestial observation, possibly for agricultural planning or ritualistic purposes.
Correct: E
The argument observes sophisticated astronomical knowledge (carvings, oriented structures) and concludes that this implies specialized astronomers or priests. The question asks for an inference.
Option (E) is the most direct and strongest inference. The premise describes 'intricate carvings' and 'structures precisely oriented' towards celestial events. Performing such precise alignments and understanding the necessary celestial calculations implies a high level of specialized knowledge and dedication that would naturally fall to a 'dedicated group or class skilled in these specific disciplines' – i.e., specialized astronomers or priests. This directly supports the conclusion given in the question text as an implication.
(A) While true that intricate carvings and structures imply artistic and architectural capabilities, this is not the specific inference about *specialized astronomers/priests* that the passage is driving towards. It's a general observation, not the precise implication.
(B) This provides a *reason* why astronomical knowledge might have been important (agricultural planning), but it doesn't directly infer the *existence of specialized roles* based on the observed evidence of knowledge. The passage states this as a *possible purpose*, not a direct inference from the observation.
(C) While possibly true, this is outside the scope of the evidence presented (carvings, structures) and doesn't support the inference about specialized astronomers/priests.
(D) This is a general statement about division of labor and technological development, not a direct inference about *this specific case* from the evidence presented. It's a broader sociological observation, not a deduction from the archaeological findings.
