The archaeologist's interpretation of the ancient symbols remained speculative, as no contemporaneous written records existed to confirm whether her reading of the iconography was accurate.
As used in the text, what does the word "speculative" most nearly mean?
proven
official
conjectural
popular
Correct Answer: C
Choice C is the best answer. The passage notes no records existed to confirm the interpretation. "Conjectural" means based on incomplete information, fitting this unverifiable interpretation.
Choice A is incorrect because "proven" contradicts lack of confirmation. Choice B is incorrect because "official" doesn't relate to evidence. Choice D is incorrect because "popular" doesn't address certainty.
