Solution:
- A. The blank requires a noun in the plural form to agree with 'magnificent animals'. Thus, 'bodies' is the correct choice.
- B. The sentence describes the places on Earth where polar bears live, implying a superlative degree. 'Coldest' is the correct superlative adjective.
- C. The blank connects the preceding clause about skilled hunters to the following clause about having a good sense of smell. 'Who' is the correct relative pronoun to refer to skilled hunters.
- D. The sentence discusses the current state of the ice in relation to climate change. 'Melts' is the correct present tense verb for the singular noun 'ice'.
- E. The blank refers to 'white giants' (polar bears) and their challenges due to climate change. 'These' is the correct demonstrative pronoun to refer to 'white giants'.
