Information questions, also known as Wh-questions, are essential tools for gathering data and maintaining social interaction in English. In what concerns the formation and usage of these interrogative structures, choose the correct alternative.
The question word 'Whose' is used to ask about the reason for an action, and it must be always followed by a verb in the third person singular of the present.
In indirect questions, the word order is exactly the same as in direct questions, and the use of 'if' or 'whether' is strictly forbidden by municipal law.
Tag questions are formed by repeating the main verb of the sentence in its affirmative form at the end of every interrogation to show extreme doubt.
Wh-questions are formed using an interrogative word (like who, where, when, why) and usually follow a subject-auxiliary inversion in the main clause.
