Explanation:

To form the present indefinite passive, we use the verb "to be" in the present tense followed by the past participle of the main verb. In the case of the first sentence, "ask" becomes "asked" in the past participle form. Therefore, the correct passive construction is "is asked".

For the future indefinite passive, we use the modal verb "will" followed by "be" and the past participle of the main verb. In the second sentence, "publish" becomes "published" in the past participle form. Therefore, the correct passive construction is "will be published".

The third sentence is in the past indefinite passive. The verb "found" becomes "founded" in the past participle form. Therefore, the correct passive construction is "was founded".

In the fourth sentence, the verb "build" becomes "built" in the past participle form. Therefore, the correct passive construction is "was built".

Finally, in the fifth sentence, the verb "clean" becomes "cleaned" in the past participle form. Therefore, the correct passive construction is "is cleaned".

In all these sentences, the subject of the sentence is receiving the action rather than performing it, which is why the passive voice is used.
