Choose the grammatically correct sentence from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Aisha watched only the first three episodes of the series before her exams began.
Order of number words:
- When “first” or “last” is used with a number such as “three”, it comes before the number.
- So we say the first three episodes, not “the three first episodes”.
Why the Other Options are Incorrect?
Option 1: If had I known about the sale, I would have bought two pairs. — Incorrect. The option uses both “If” and “had I known”. When “had” comes before the subject, “if” is dropped.
Corrected: Had I known about the sale, I would have bought two pairs.
Option 2: Cycling to college is cheaper than to buy a monthly bus pass. — Incorrect. The two things compared must be in the same form. “Cycling” is an -ing form, so the second one must be “buying”.
Corrected: Cycling to college is cheaper than buying a monthly bus pass.
Option 4: The organisers have not decided whether the book fair will be held indoors nor outdoors. — Incorrect. “Whether” is followed by “or”, not “nor”.
Corrected: The organisers have not decided whether the book fair will be held indoors or outdoors.
