Concept:Dictionary order is determined by comparing words letter by letter from left to right. The earliest differing letter decides the sequence.
Explanation:Start with the common prefix "Epi". The first word is "Epic" because after "Epi", the next letter is 'c', which comes before 'd' (in "Epid..."). Thus, Epic (2) is first.
Now compare the remaining words that begin with "Epid": Epidemic, Epidermis, Episcopal, Episode. After "Epid", the next letters are: Epidemic has 'e', Epidermis has 'e', Episcopal has 's', Episode has 's'. Since 'e' comes before 's', Epidemic and Epidermis come before Episcopal and Episode.
Between Epidemic and Epidermis: after "Epidem", Epidemic has 'i' (actually "Epidemi...") while Epidermis has 'r' (Epiderm...)? Let's clarify: Epidemic = E-p-i-d-e-m-i-c, Epidermis = E-p-i-d-e-r-m-i-s. Comparing after "Epid", the next letters are e (both), then m (Epidemic) vs r (Epidermis). 'm' comes before 'r', so Epidemic (1) comes before Epidermis (5).
Now compare Episcopal and Episode: after "Epis", Episcopal has 'c' (Episco...), Episode has 'o' (Episod...). 'c' comes before 'o', so Episcopal (4) comes before Episode (3).
Thus, the correct dictionary sequence is: Epic (2), Epidemic (1), Epidermis (5), Episcopal (4), Episode (3). This corresponds to the order 2,1,5,4,3.
