Question

antarctica is surrounded by freezing cold water. some valleys in antarctica are the driest places on earth. however therefore ← joining words rewrite the sentences, and use one of the joining words in the correct place. your final response should be two sentences.

Explanation:

The task involves using a joining word (conjunction) to connect two related sentences, focusing on logical coherence. "However" is suitable as it shows a contrast: Antarctica is surrounded by cold water, but some valleys are the driest (unexpected contrast to being surrounded by water). So we rewrite: "Antarctica is surrounded by freezing cold water. However, some valleys in Antarctica are the driest places on Earth."

Answer:

Antarctica is surrounded by freezing cold water. However, some valleys in Antarctica are the driest places on Earth.
