IMMINENT means about to happen very soon - something that is impending or threatening to occur immediately. The other options are incorrect: high in status means eminent (not imminent), remaining within is the opposite of imminent, and powerful refers to strength.

IMPERMEABLE means not allowing passage (of fluids, gases, or other substances) - something that cannot pass through. Common examples include impermeable rock layers or waterproof materials. The other options (temporary, opinionated, disturbed) do not relate to the meaning.

IMPEACH means to accuse (especially a public official) of misconduct - to bring formal charges against someone.

[or significance, as of a word/ phrase/document]

IMPASSIVE means without emotion - showing no reaction, remaining calm and stoical. Someone who is impassive does not show their feelings or get excited. The other options are incorrect: exciting attention is opposite, dignified is related but different, and disturbed means agitated.
