Fill in the blank with the correct article:
The shuttle bus from the railway station to the fort runs on ________ hourly basis.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → an
Complete sentence: The shuttle bus from the railway station to the fort runs on an hourly basis. The h in “hourly” is silent, so the word begins with the vowel sound “ow”.
| Option | When to use | Example |
|---|---|---|
| (1) a | before a consonant sound | The shop gave us a handwritten bill. |
| (2) the | a particular thing already known; in “on ... basis” the basis is not a known one and only tells how often | The bus we took this morning was full. |
| (3) No article | plural or uncountable nouns used in a general sense; “basis” is a singular noun that can be counted, so it needs an article | Buses leave the station every hour. |
| (4) an (answer) | one thing, before a vowel sound; the first sound decides, not the first letter | Rahul waited for an hour at the bus stop. |
