1. Since it's too late to change my mind, I am _____ to carrying out the plan.
A. Committed. B. Obliged. C.Engaged. D. Resolved.
Which is right, and why.
Answer: the only word which you definitely cannot use is 'engaged'. Obliged would need to become 'obligated'. The only word you can use without changing the sentence at all is 'committed'. Other options would be ... I am obligated to carry out the plan. OR I have resolved to carry out the plan. (resolved can be used although it is really too formal for this informal type of sentence talking about changing your mind. Why are these words correct? Well, essentially they mean the same thing, whereas 'engaged' is really used more for when you are busy with something else, not the commitment you are referring to.
2. What does appeal to mean in this sentence:
I reject any religious doctrine that does not appeal to reason, and is in conflict with morality.
Answer: I consider this like 'be attractive to reason', in other words, if the religious doctrine doesn't make sense logically it will be rejected.
