Question

Correct the sentence at the underlined point.
But in all these cases conversion from one scale to another is easy because scales have well-formulated.

• A. Can be well-formulated
• B. were well-formulated
• C. Well-formulated
• D. No improvement

Answer 1

The correct option is A Can be well-formulated

'Have' here indicates possession without 'be' verb and there is nothing to possess in the sentence. Only option A fits into the context of the sentence without adding any new errors. A is the answer.
