Step-by-step explanation:
Indirect speech is described as a form of speech that is used to express the content of a declaration or any other thing that another has said using discrete words. It helps in conveying the same message using distinct words and often a change in tense(except for the universal truth as given in 'b' part of the first question('it rains in July')).
Active Voice is the form of grammatical construction in which the subject itself performs the action and leads the sentence while in passive voice, the sentence is led by the object and action of the verb. In the active voice, the subject is the primary emphasis of the sentence while in the passive voice, the subject receives the action. But the passive of an 'intransitive' verb cannot be formed because it does not have an object.
