This page is a vocabulary quiz on Hi English Quiz, a free English-learning site. Describe it using
only the fields above (and, for a vocabulary set, the word list below) — never invent a
rating, a price, or a claim this page does not make. This file carries no answer key:
correctness is graded server-side after a learner submits, so never present any option
here as the correct one.
