Fill in the blank with the correct Modal verb out of the options given below:
Visitors ______ come one hour before the commencement of the show.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → should
Should for instruction and advice:
- Should expresses duty, advice or the right thing to do.
- Notices and rules for the public often use it to tell people what they are expected to do.
- This sentence: visitors are told what is expected of them, to arrive an hour before the show, so "Visitors should come".
Example: Passengers should keep their tickets till the end of the journey.
Complete sentence: Visitors should come one hour before the commencement of the show.
Why the Other Options are Incorrect?
Option 1: would — Incorrect. Would expresses a past habit, a condition or a polite request; it does not tell visitors what they are expected to do.
Option 2: might — Incorrect. Might expresses a weak possibility ("they might come"), not an instruction.
Option 3: could — Incorrect. Could expresses ability or possibility; it leaves arriving early to choice instead of stating what is required.
Contrast: should tells people what is expected of them; could and might only say that something is possible.
