Select the most appropriate option that can substitute the underlined segment in the given sentence.
My cousin works day and night to achieve success in life.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. around the clock.
-
"Day and night" emphasizes effort over an extended period, often implying dedication and hard work. It suggests working throughout the day and into the night, but not necessarily every single moment.
- Example: She studied day and night for the exam. (She worked hard for long hours, possibly with breaks.)
-
"Around the clock" is a phrase that means continuously, without stopping, as if covering all 24 hours of the day. It implies nonstop activity.
-
Example: Doctors worked around the clock to save the patients. (They worked without breaks or in shifts to provide continuous care.)
-
Both phrases mean working continuously or with great dedication, but "around the clock" emphasizes constant, nonstop effort more explicitly.
