Textbook test
Twenty fill-in-the-blank questions, drawn at random from forty, on An Enquiry into the Obligations of Christians (1792) — William Carey. You need 18 of 20 to pass. Type the missing word or phrase and press Check (or Enter): each answer is marked at once. Capitals, accents and punctuation do not matter; you may answer in English or Spanish. If you fall short, review the book and try again after a short wait; the next attempt draws a fresh twenty.
