Question

winding through the ice atop norways 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 present perfect tense construction: "archaeologists have unearthed..." where the main verb "unearthed" follows the auxiliary "have" (forming present perfect: have + past participle). There is no need for a colon, dash, or comma after "unearthed" here because the direct object ("knives, horseshoes, wool tunics, and thousands of other artifacts") directly follows the verb. So the correct choice is the one with just "unearthed" (no punctuation after it).

Answer:

D. unearthed
