Identify the part of the sentence that contains an error.
A lot of delay in travel is caused / by poor planning and a lack of good management / on behalf of the railway staff.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → on behalf of the railway staff
On behalf of means in place of someone or as their representative. The sentence wants to say whose fault the poor planning is. For that we use on the part of, which means "done by" someone.
Option 1: A lot of delay in travel is caused — No error.
Option 2: by poor planning and a lack of good management — No error.
Option 3: on behalf of the railway staff — Error. “on behalf of” should be “on the part of”.
Corrected: A lot of delay in travel is caused by poor planning and a lack of good management on the part of the railway staff.
