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.

[urgent in demanding]

IMPEACH means to accuse (especially a public official) of misconduct - to bring formal charges against someone. While impeachment can lead to removal from office, the word itself means to accuse/charge, not to remove. Slander means to make false statements, and putting in jail is a consequence, not the meaning.

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