Synonyms

Ukase is an authoritative decree or order, especially one issued by a Russian tsar. It refers to a proclamation or command that must be obeyed. 'An authoritative decree' is the exact definition. 'Contract', 'Bond', and 'Agreement' imply mutual consent, which is not what ukase means.

Wallow means to roll about or indulge in something, especially something pleasurable or self-indulgent. It can refer to physically rolling (like pigs in mud) or metaphorically indulging in emotions or situations. 'Welter' means to roll, toss, or wallow, making it a close synonym. 'Ignore', 'Destroy', and 'Avoid' are the opposite of wallowing.

Tumult means a loud, confused noise, or a state of commotion, uproar, or disorder. It refers to chaotic, noisy disturbance. 'Clamour' means a loud and confused noise, which is the closest synonym. 'Harmony', 'Peace', and 'Silence' are all antonyms of tumult.

Whelp specifically means the young offspring of a dog, wolf, or other carnivorous mammal. It is the term for a young puppy or cub. 'Pup' directly means a young dog, making it the correct answer. 'Chick', 'Cub', and 'Kitten' refer to young animals of different species.

Trope refers to a figurative or metaphorical use of a word or expression, or a recurring theme or device in literature and art. In literary studies, a trope is a figure of speech or artistic device. 'Figure of speech' is the correct literary term. 'Dialect' refers to regional language patterns, 'Stanza' to poetry structure, and 'Story' to narrative - none of which define trope.

Unruly means difficult to control or discipline, which is closest in meaning to lawless. Lawless suggests absence of law or control, matching the core meaning of unruly behavior. Modest, hatred, and docile are unrelated - docile is actually an antonym meaning obedient.
