Unless you work hard, you not be able to pass the exams?

Appeared in: PGIMS Rohtak NO - 2017

Explanation

The sentence is a first conditional, expressing a likely and definite future result.
The structure 'Unless + present tense, ... will + verb' is used to show a strong cause-and-effect relationship.
'Will' is used to indicate certainty or a definite future outcome based on the condition.
In this context, not working hard will certainly lead to the inability to pass the exams.

Option A: This option expresses ability. The phrase 'can not be able to' is grammatically redundant as 'can' and 'be able to' convey the same meaning.
Option C: This option expresses possibility, which is too weak for the context. The word 'Unless' implies a much stronger and more certain consequence.
Option D: Similar to 'may', this option expresses possibility, but it is even weaker. It does not fit the strong cause-and-effect link implied by 'Unless'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Use of Modal Verbs in Conditional Sentences as background academic context rather than a clinical decision trigger.
This question tests general English grammar, not a clinical nursing concept.
Proficiency in grammar is crucial for nurses to ensure clear, accurate, and professional communication in patient charting, reports, and interactions with patients and colleagues.
What if the sentence was about permission? If the sentence was 'You ___ not enter without a pass,' the correct word might be 'may' (formal permission) or 'cannot' (prohibition).

How to Approach the Question

First, identify the type of sentence. This is a conditional sentence starting with 'Unless'.
Understand that 'Unless' means 'if not'. So, the sentence can be rephrased as: 'If you do not work hard...'
Analyze the relationship between the two parts of the sentence. The first part sets a condition, and the second part describes the consequence.
Determine the level of certainty implied. 'Unless' typically introduces a strong, definite consequence.
Evaluate the given modal verbs: 'Will' for certainty, 'Can' for ability, and 'May'/'Might' for possibility.
Select the modal verb that best fits the context of a certain future outcome, which is 'will'.
