Here in his editing of 𝓟 for the 1837 edition, Joseph Smith changed the subject pronoun it to they (although he actually crossed out the following be rather than the it). Apparently, Joseph’s intent was to reinterpret the original it as a plural so that it would specifically refer to Zeezrom’s request in the previous verse:
In other words, Joseph’s they refers to the plural the questions. This suggestion was, however, ignored in the 1837 edition, probably because the subject it is not actually a regular pronoun that expects an antecedent but instead is an expletive it that fills the subject position.
Summary: Maintain the original singular pronoun it in Alma 11:22; Joseph Smith considered replacing it with they so that the subject pronoun would refer to the preceding the questions.
