Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. grass is always greener on the other side.
Error concept: Wrong idiomatic expression.
What is wrong: The phrase 'The grass is always redder on one side' is incorrect because the well-known idiom uses 'greener', not 'redder'.
Grammatical concept: Idioms are fixed expressions whose words cannot be altered without changing or losing the meaning. The idiom 'the grass is always greener on the other side' means that people often think others are in a better situation than they are.
Incorrectness of the concept in context: Using 'redder' instead of 'greener' changes the idiom and makes the sentence meaningless.
How to correct: Replace the incorrect phrase with the proper idiom: 'grass is always greener on the other side'.
Correction: grass is always greener on the other side.
Final sentence: Don’t assume that everyone but you is happy. The grass is always greener on the other side.
Hence, the chosen option is correct.
