Hi Selly, Well done for having a go! The first one is a 'verb pattern' problem - we use the verb 'commit' in a specific way (a good dictionary should explain this) - so, we 'commit [to] something' where 'something' is a noun. In your first example, you have the choice between a gerund phrase 'doing this work' (have you learnt about these yet?) which functions as a noun, or 'to do' which is an infinitive. Therefore, because of the required verb pattern for 'commit', you need to choose (a). The second one is more tricky because the 'to' really stands for 'in order to', which means 'with the aim of achieving' and the pattern for this is to be followed by a 'bare infinitive', in this case 'make'. There is quite a lot of grammar here, and the best way to learn verb patterns is to make a note of the patterns as you find them - and just remember that many of them have more than one pattern. In addition, lots of reading, speaking and listening to English will help. Hope this helps. Rachel

Hi Selly, why don't you have a go at the question yourself first, it's the best way to learn :)

1. a. I am commited to DOING this work for charity. - this is fine. b. I am commited to DO this work for charity. - this is fine. 2. a. I would like to hear what he told people to MAKING them believe. - this is not a correct use of "making." b. I would like to hear what he told people to MAKE them believe. - this is fine.

I'll help you with the first one: Examples: I am committed to this job. I am committed to my family. Therefore, "I am committed to..."? :)
