Arrange the given words in the sequence in which they occur in the dictionary.
i. Temerity
ii. Temporary
iii. Tempered
iv. Temperature

Let's compare the words letter by letter to arrange them alphabetically:
All words start with "Tem". Let's look at the 4th letter:

i. Temerity (4th letter is 'e')

ii. Temporary (4th letter is 'p')

iii. Tempered (4th letter is 'p')

iv. Temperature (4th letter is 'p')

Since 'e' comes before 'p', i. Temerity is the 1st word.

Now compare the remaining words starting from the 5th letter:

ii. Temporary (5th letter is 'o')

iii. Tempered (5th letter is 'e')

iv. Temperature (5th letter is 'e')

Since 'e' comes before 'o', ii. Temporary will be the last word.

Now compare iii and iv:

iii. Tempered (6th letter is 'r', 7th is 'e', 8th is 'd')

iv. Temperature (6th letter is 'r', 7th is 'a')

Comparing the 7th letters of iii and iv ('e' vs 'a'): 'a' comes before 'e'.
So, iv. Temperature comes before iii. Tempered.

The correct alphabetical sequence is:
i → iv → iii → ii
