Question : The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
You should / see a oculist; / your eyes look / worse today.
Option 1: your eyes look
Option 2: You should
Option 3: worse today
Option 4: see a oculist;
Correct Answer: see a oculist;
Solution : The correct choice is the fourth option.
Explanation: The use of a or an before a noun depends on the sound that follows it, not the actual letter. When a word begins with a vowel sound, you should use an instead of a to make the sentence grammatically correct. In this case, oculist starts with a vowel sound "o", so it should be an oculist.
Therefore, the correct sentence should be: "You should see an oculist; your eyes look worse today."
