    TBH, any textbook you teach out of at a university level that makes this kind of wrong statements where it matters sounds like a very bad textbook indeed. Can you change the textbook, or is it set? (About "where it matters": I am fine with an "Introduction to propositional logic" that uses either one as examples of propositions or statements, in which case we would not by worrying about exceptions, would we? And of course if we are looking at primary or [some] secondary education textbooks, shortcuts like the second statement could be left standing.) Commented Nov 18 at 8:33

    I cleaned up some discussion about the examples. My understanding is that the remaining example is correctly transcribed from an actual textbook. Commented 2 days ago

    @cag51 Though searching that phrase suggests it comes from an Indian grade school textbook, not a university-level textbook. Commented 2 days ago

    Simply "Almost all" living things instead of "All" and the statement is fixed! :-) Commented yesterday
