Cast aside

To reject

The answer is to reject.

The idiom "cast aside" means to get rid of someone or something, usually because they are no longer wanted or needed. It can also mean to dismiss or ignore someone or something.

In this case, the most appropriate meaning is to reject. The idiom "cast aside" is often used to describe someone who is rejected by their loved ones, or someone who rejects their own dreams or goals.

The other possible meanings of the idiom "cast aside" are not as appropriate in this context. "To blow up" means to explode, which is not what is happening in the sentence. "To bear with" means to tolerate something, which is not the same as rejecting it. "To display" means to show something, which is not the opposite of rejecting it.
