Explanation:

To determine the word that comes last in alphabetical order, we need to compare the words based on their first letter. If the first letter is the same, then we move on to the second letter, and so on, until a difference is found or one word ends.

Comparison of given words:

- Transport
- Transist
- Transmit
- Translate

Step 1: Comparing the first letter of each word

- Transport
- Transist
- Transmit
- Translate

The first letters are 'T' for all the words, so we move on to the second letter.

Step 2: Comparing the second letter of each word

- ransport
- ransist
- ransmit
- ranslate

The second letters are 'r' for all the words, so we move on to the third letter.

Step 3: Comparing the third letter of each word

- ansport
- ansist
- ansmitt
- anslate

The third letters are 's' for 'sport' and 'sist', 'm' for 'mitt', and 'l' for 'late'.

Step 4: Comparing the fourth letter of each word

- nsport
- nist

- late

The fourth letters are 'p' for 'sport', 'i' for 'ist' and 'mitt', and 'e' for 'late'.

Step 5: Comparing the fifth letter of each word

- sport
- ist
- mitt
- late

The fifth letters are 'o' for 'sport', 's' for 'ist' and 'mitt', and no letter for 'late' as it ends.

Step 6: Comparing the sixth letter of each word

- port
- st
- itt

The sixth letter is 'r' for 'port', 't' for 'st', and 't' for 'itt'.

Step 7: Comparing the seventh letter of each word

- ort
- t
- t

The seventh letter is 't' for all the words.

Step 8: Comparing the eighth letter of each word

The eighth letter is 't' for 'rt' and no letter for the other words as they end.
