The MCQs were an abomination. Here are the words I remember:

Synonyms:
Alluvial
Bibulous
Demiurge
Pabulum
Plagiarism
Sot

Antonyms:
Anachronistic
Caitiff
Demagogue
Feral
Nymphomaniac
Quisling

Unsure if it was synonym/antonym:
Hagiographic

I even knew a few words, but the choices were so similar that there appeared to be more than one right answer. For example, two of the antonym choices for feral were domesticated and tamed, but aren't those synonyms of each other?
