Preview: Explanations
1."to hear"(b)
After adjectives describing feelings (happy, glad, pleased, sad, surprised), use a to-infinitive. 'She was happy to hear' is correct.
2."to lift"(a)
The pattern 'too + adjective + to-infinitive' means 'so much that it is not possible'. 'Too heavy to lift' = so heavy that no one can lift it.
3."to live"(c)
The pattern 'adjective + enough + to-infinitive' means 'sufficiently'. 'Old enough to live on his own' = sufficiently old to live independently.
4."to do"(d)
After question words (what, how, where, when, which), use a to-infinitive. 'I don't know what to do' is correct.
5."to take"(a)
After the adjective 'ready', use a to-infinitive. 'We are ready to take the exam' is correct.
