Many archaeologists will tell you that categorizing excavated fragments of pottery by style, period, and what objects they belong to relies not only on standard criteria, but also on instinct developed over years of practice. In a recent study, however, researchers trained a deep-learning computer model on thousands of images of pottery fragments and found that it could categorize them as accurately as a team of expert archaeologists. Some archaeologists have expressed concern that they might be replaced by such computer models, but the researchers claim that outcome is highly unlikely.
Which finding, if true, would most directly support the researchers’ claim?
A) In the researchers’ study, the model was able to categorize the pottery fragments much more quickly than the archaeologists could.
B) In the researchers’ study, neither the model nor the archaeologists were able to accurately categorize all the pottery fragments that were presented.
C) A survey of archaeologists showed that categorizing pottery fragments limits the amount of time they can dedicate to other important tasks that only human experts can do.
D) A survey of archaeologists showed that few of them received dedicated training in how to properly categorize pottery fragments.
C) A survey of archaeologists showed that categorizing pottery fragments limits the amount of time they can dedicate to other important tasks that only human experts can do.
