Question

climate conditions from thousands of years ago cannot be directly measured, so paleoclimatologists use ice core analyses to ______ ancient atmospheric conditions. these approximations allow researchers to better understand historical climate patterns and their implications for the future. which choice completes the text with the most logical and precise word or phrase? choose 1 answer: a conceal b exaggerate c disregard d estimate

Explanation:

The text states that climate conditions from long ago can't be directly measured. So, paleoclimatologists use ice - core analyses. The key is that they are making an approximation (as mentioned in the text).

• Conceal: means to hide. But ice - core analyses are used to find out about ancient atmospheric conditions, not to hide them. So this is incorrect.
• Exaggerate: means to overstate. There is no indication in the text that they are overstating the conditions. So this is wrong.
• Disregard: means to ignore. But the whole point is that they are trying to understand (not ignore) the ancient atmospheric conditions. So this is incorrect.
• Estimate: means to approximate. Since they can't measure directly and are using an approximation (ice - core analyses), “estimate” fits the context.

Answer:

D. estimate
