The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
Dr. Paramahamsa has been working / as a Assistant Professor / of Mathematics / in IIT Madras for five years.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. as a Assistant Professor.
The error lies in the use of the article 'a' before the word 'Assistant'.
'Assistant' begins with a vowel sound (/ə/), so the correct article should be “an”, not “a”.
The correct phrase is: “as an Assistant Professor”
Let’s quickly check the other segments:
'Dr. Paramahamsa has been working' – grammatically correct (present perfect continuous tense).
'of Mathematics' – correctly describes the subject of specialization.
'in IIT Madras for five years' – correct use of location and time duration.
