Select the most appropriate word or phrase to complete the following sentence:-

Once you _____ into the routine, you will find the work is quite easy.

are settled

The correct answer is Option (1) → are settled

The sentence follows the pattern: Once you + present tense, future result

Meaning: after you become settled, the work will seem easy. So: Once you are settled, you will find the work is quite easy.

The other options are incorrect:

• had settled → past perfect; does not fit with “you will find”

• settled → simple past; incorrect structure

• will settle → future tense cannot be used after “once”
