Identify the errors in the given sentence and choose the sentence that rectifies these errors.
Doctor she spoke to at a exhibition was very knowledgeable. The medicines prescribed by him have proved excellent for my father.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. The doctor she spoke to at the exhibition was very knowledgeable. The medicines prescribed by him have proved excellent for my father.
Errors in the original sentence:
1. Missing article 'The' before 'doctor' (a specific doctor is being referred to).
2. Incorrect article 'a' before 'exhibition' — it should be 'the' because it refers to a specific event.
Option 1 correctly uses 'The doctor' and 'the exhibition', and keeps the rest of the sentence grammatically correct.
Why others are incorrect:
2. Uses 'A medicines' – wrong because 'medicines' is plural and cannot take 'A'.
3. Missing 'the' before 'exhibition'.
4. Missing 'The' before 'doctor'.
