Highlight the paragraph and right-click. Select 'Cut.' It will delete the text and keep it copied. Go to page 27, find the appropriate place, right-click again, and hit paste. Good luck, sorry I'm late.
Answer:
The answer to your question would be that the revision that combines the sentence using a subordinating clause and subordinating conjunction is the following one: East Antarctica is covered by massive layers of ice which is thousands of meters thick.
Explanation:
The revised version of the sentence includes an essential relative clause. Essential relative clauses limit an ambiguous noun, that is, they complete the meaning of the sentence. The essential clause helps identify the noun it modifies. Consequently, if they are dropped, the meaning of the sentence is altered (see 1).
1) East Antarctica is covered by massive layers of ice
That's easy. the possessive pronoun is ''person'' because possessive pronouns describe what the noun is in more detail
I know this is late but I hope this still helped.
