Final answer:
Sentence (7) - 'The next nation Hitler set his sights on refused capitulation.' is not logically connected to the rest of the paragraph.
Step-by-step explanation:
In the given paragraph, all sentences are logically connected except for sentence (7) - 'The next nation Hitler set his sights on refused capitulation.' This sentence is not logically connected because it introduces a different topic - the refusal of Poland to surrender to Hitler's invasion. The rest of the paragraph discusses the reactions of other nations to Poland's resistance.
