OE


The different-direction trigger word to focus on here is instead, which tells you that the type of person she is should be different from one who has a secret. Inscrutable is similar in meaning to an enigma behind the celebrated smile, so choice (E) is incorrect. Lisa del Giocondo may well have been dulcet or comely, but there is no supporting evidence for these words in the sentence. Since you are looking for a word that refers to someone who doesn’t keep secrets, choices (B), guileless, and (F), ingenuous, are the best answers.
