The correct answer is B: A perfect dam has been built by them across the river.
Explanation:
To determine the correct sentence, we need to understand the grammar and structure of each option.
Option A: Across the river a perfect dam was built.
- This sentence has a passive voice and reverses the word order.
- While it is grammatically correct, it doesn't convey the same meaning as the original sentence.
Option B: A perfect dam has been built by them across the river.
- This sentence correctly uses the passive voice and maintains the original meaning.
- It states that a perfect dam has been built by a group referred to as "them" across the river.
Option C: A perfect dam should have been built by them.
- This sentence changes the tense and implies a sense of obligation or expectation.
- It does not accurately reflect the meaning of the original sentence.
Option D: Across the river was a perfect dam.
- This sentence alters the word order and does not convey the same meaning as the original sentence.
- It suggests that a perfect dam is located across the river without mentioning who built it.
In conclusion, option B is the correct answer as it maintains the passive voice and accurately conveys the meaning of the original sentence.
