Which of the following sentences uses a modal wrongly?

The correct answer is Option (3) → If I would have more time, I would learn the tabla.

Would comes in the result part, not the if-part:

• The given sentence says “If I would have more time”.
• For something imagined about now, the if-part takes the simple past, like “had”.
• Would + base verb (the simple form of the verb, like go, eat) comes only in the other part, the imagined result.
• Corrected: If I had more time, I would learn the tabla.

Why the Other Options are Incorrect?

Option 1: Dare she complain to the warden about the mess food? This sentence is correct. In a question, “dare” can work as a modal. It comes before the subject and takes the base verb “complain”.

Option 2: The old well in our village has to be cleaned before the monsoon. This sentence is correct. “Has to be” + past participle (V3) is the passive of “has to”. It shows that the cleaning is necessary.

Option 4: Should you miss the last bus, call Papa from the bus stand. This sentence is correct. “Should” at the start of a sentence can mean “if”. “Should you miss” means “if you miss”.
