3. Circle the odd word out: a) flake, birthday, pavement, vital; b) suddenly, escape, dangerously, quickly; c) during, after, through, nobody

a) birthday — the other words contain the letter sequence “a...e” or are connected with the sound /eɪ/ differently? The intended odd word is vital, because it has two syllables with the stress on the first, unlike the remaining words. b) escape — it is a verb; the other words are adverbs. c) nobody — it is a pronoun; the other words are prepositions.
