Question

winding through the ice atop norway’s jotunheim mountains is the lendbreen pass, an ancient route that was used by hunters, farmers, traders, and travelers in the middle ages before eventually falling into disuse. recently, archeologists have ______ knives, horseshoes, wool tunics, and thousands of other artifacts from the icy pass. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a unearthed— b unearthed: c unearthed, d unearthed

Explanation:

The sentence structure here is a simple past - present perfect construction where the main verb "have unearthed" is used to show an action that has been completed. After the verb "have unearthed", we just need the verb form without any punctuation because the list of artifacts (knives, horseshoes, etc.) is the direct object of the verb. Option A has a dash which is unnecessary, Option B has a colon which is used for introducing a list or explanation but here the artifacts are the object of the verb, Option C has a comma which is incorrect as there is no need for a comma after the verb in this context. Option D provides the correct verb form without any incorrect punctuation.

Answer:

D. unearthed
