In the following question, a sentence has been given in Active Voice. Out of the four alternatives suggested, select the one which best expresses the same idea in Passive Voice: "The authorities will reward you for your hard work."

Introduction / Context:
This question tests simple future tense conversion from active to passive voice. The active sentence is "The authorities will reward you for your hard work." You need to find the passive version that keeps the same future time reference and clearly expresses that you are the receiver of the reward.

Given Data / Assumptions:

• Active sentence: "The authorities will reward you for your hard work."
• Subject: "The authorities".
• Object: "you".
• Verb phrase: "will reward" (simple future).
• Extra phrase: "for your hard work".

Concept / Approach:
To convert a simple future sentence to passive voice, we use the structure "will be + past participle". The object "you" becomes the subject. So "will reward you" changes to "you will be rewarded". Then we add the agent "by the authorities" and keep the reason phrase "for your hard work". Therefore, the correct passive sentence is "You will be rewarded by the authorities for your hard work."

Step-by-Step Solution:
Step 1: Identify the object that will become the passive subject: "you".Step 2: Convert "will reward" to passive using "will be rewarded".Step 3: Place "you" at the beginning: "You will be rewarded".Step 4: Add the agent phrase "by the authorities".Step 5: Append the phrase "for your hard work" to preserve the cause of the reward.

Verification / Alternative check:
Check meaning: Original sentence promises a future reward given by the authorities to you because of your hard work. The passive sentence "You will be rewarded by the authorities for your hard work" expresses exactly the same promise, with the same future reference and the same cause. The change is only in focus: from the authorities to you as subject. This confirms that the transformation is correct.

Why Other Options Are Wrong:

• Option B: Uses "would be rewarded", which expresses a conditional or less certain future, not the definite future indicated by "will".
• Option C: "The authorities will be rewarded by your hard work" reverses the roles, suggesting that authorities receive the reward, which changes the meaning.
• Option D: Has both wrong subject and "would" instead of "will".
• Option E: Uses present perfect passive "have been rewarded", which implies the action is already complete, not future.

Common Pitfalls:
One common error is to change "will" to "would" when moving to passive, which alters the degree of certainty. Another error is misplacing the agent and making the authorities the receivers instead of the givers. Remember the pattern: Simple future active "will + verb + object" becomes Simple future passive "object + will be + past participle + by + subject". Apply this mechanically when you are unsure.

Final Answer:
The correct passive voice transformation is "You will be rewarded by the authorities for your hard work."
