Answer 1

The correct answer is Option 1.

Key Points

Option 1 is the only grammatically correct sentence that clearly conveys the intended meaning.
Option 2 is incorrect because the word order is wrong.
Option 3 is incorrect because the structure "thought once been flat" is not grammatically sound.
Option 4 is incorrect because "once think to be flat" does not make grammatical sense.

Therefore, the correct answer is 1.

Correct Sentence: "The earth was once thought to be flat."

Additional Information

Option 2: "once flat to be" – The word order is incorrect, making the sentence meaningless.
Option 3: "thought once been flat" – This structure is incorrect and does not convey a clear meaning.
Option 4: "once think to be flat" – This phrase is grammatically incorrect and unclear.
No error – This would be correct if all options were valid, but only Option 1 is grammatically and logically correct.
