Q:

In the following question, a sentence is given with some bold words which may contain errors. Below the sentence, a table is given with two columns in which column 'A' contains the list of bold words, and in column 'B' the suggested corrections are listed. You have to choose the best alternative among the four given options. If no correction is required against the given bold words, mark (E), i.e., "None of the above" as your answer.

The Bill states that companies with more than 10 employees would periodically debate specific terms with their workers, publish their own charter, and create an Employee Welfare Committee consisting of representatives of the company’s workforce.

A) Both (1)-(5) and (4)-(8) B) (4)-(8)
C) (1)-(5) D) (3)-(7)
 
Answer & Explanation Answer: C) (1)-(5)

Explanation:

'Debate' results in only one of the parties involved in the argument to win. But, when employees and employers discuss the terms of working, the end results must satisfy both and not just one of them. This is called 'negotiation', not a debate. Also, employees are the same as that of workers. So, no change is required here. A committee is formed by 'representatives' from various factions. 'Capital' doesn’t require representation.
