Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. a textbook states: found in a remote alaskan cave, the bone scrapers and stone hammers are some of the oldest artifacts known in north america. what does the word \artifact\ mean in this context? use these dictionary entries to answer the question:
art- (prefix) skill
fac (root) make, do
options: fossils, skeletons, rocks, man - made items

Explanation:

Using the prefix "art - " (skill) and root "fac" (make, do), "artifact" implies something made with skill. The context has bone scrapers and stone hammers, which are man - made. Fossils, skeletons, and rocks are not made by people, so "man - made items" fits.

Answer:

D. man - made items
