Show Hint
When using "refused to", always follow it with the base form of the verb (infinitive without "to"). This structure is common in sentences involving refusal or negation.
The phrase "refused to" is followed by the base form of the verb, so the correct choice here is "give in". The phrase means that despite being tired, the person did not yield or surrender. Thus, the correct answer is option (1).
