• While learning about the passive voice form, students also learn about the use of verb form.
• Passive voice is used to emphasize the action (the verb) and the object of a sentence rather than the subject.
• This means that the subject is either less important than the action itself or that we don’t know who or what the subject is.
• Hence, option D is correct.

For interchange of superlative to positive degree, the rule that is followed: ‘Very few + modifier + verb + as + positive degree + as + subject. The given sentence is in superlative form. All other options are inappropriate. So, the correct answer will be: ‘Very few tragedies of Shakespeare is as popular as King Lear.’

For interchange of positive to comparative degree, the rule that is followed: ‘Subject + verb + comparative degree + than most other + modifier.’ The given sentence is in positive form. All other options are inappropriate. So, the correct answer will be: ‘John is more industrious than most other boys.’

The given statement is in indirect speech. Its direct speech will be: Mona said “She does not like computers.” While changing from direct to indirect speech, simple present tense sentence changes into simple past tense.

The given statement is in direct speech. Its indirect speech will be: She said that she had been working in a factory. While changing from direct to indirect speech, present perfect continuous tense changes into past perfect continuous tense.

For the given sentence, ‘integrated’ is a suitable option as it means to end the separation of people by race, sex, national origin, etc., in an organization or in society.

So, the correct answer will be: The more your actions and thoughts are allied and integrated the happier you grow.
