Question

to determine the approximate age of wooden tools excavated from an archaeological site in spain, archaeologist joseba rios - garazar and colleagues collected samples of sediments surrounding the tools; these samples were then analyzed using a method known as optically stimulated luminescence (osl) dating. osl dating indicated that the tools were between 50,000 and 137,000 years old. which choice completes the text with the most logical transition? a) similarly. b) ultimately. c) in addition, d) by comparison

Explanation:

The sentence before the blank is introducing the OSL - dating method and sample - analyzing process, and the sentence after the blank gives a time - range result of the dating. "Ultimately" is the most logical transition as it indicates reaching a final conclusion or result. "Similarly" is for showing similarity, "In addition" is for adding more information, and "By comparison" is for making a comparison.

Answer:

B. Ultimately
