Select the option that indicates the correct arrangement of the given words in the order in which they appear in an English dictionary.
Expert

Exotic

Explicit

Expense

Expanse

Let's arrange the words according to alphabetical order (dictionary style): All words start with the prefix "Ex". Let's look at the 3rd letter of each word:
Expert

Exotic

Explicit

Expense

Expanse

The letter 'o' comes before 'p', so Exotic (2) is the first word.

Now let's sort the remaining words, which all start with "Exp":

Expert

Explicit

Expense

Expanse

Comparing the 4th letters ('e', 'l', 'e', 'a'), 'a' comes first. Thus, Expanse (5) comes next.

Now compare Expert (1) and Expense (4). Both have 'e' as the 4th letter. Look at the 5th letters:

Expert vs Expense ⟹ 'n' comes before 'r'. Thus, Expense (4) comes before Expert (1).

Finally, Explicit (3) comes last because 'l' comes after 'e'.

The complete alphabetical sequence is: 2, 5, 4, 1, 3.
