Question

'Ravi works for a company' is an adjective clause

Answer 1

No, it is not an adjective clause... We have to complete it with an adjective clause that is., Ravi works for a company which is one of the leading companies

Answer 2

no it isn't an aj clause. to make it an aj clause, write it as 'Ravi works really hard for a company' where 'really hard' is an aj clause
