Which word is most similar in meaning to the word 'endeavours' as used in the passage? (Para 1)

The word 'endeavours' in the context 'This has been the pattern of man's endeavours for freedom throughout history' refers to man's earnest efforts or attempts to achieve freedom. 'Attempts' is the closest synonym because both words convey a serious, purposeful try to achieve something. 'Movements' implies organised social action, 'actions' is too general, and 'challenges' refers to difficulties faced rather than efforts made. Therefore, 'attempts' is the most appropriate synonym.
