Birds are the only vertebrates that can fly;
-the elephant is the only mammal with just one pair of mammary glands;
-a skunk’s anal glands are used to spray a foul odor at attackers.
The three statements above answer this question: which of the following is (are) unique to animals? The answer is that birds are the only vertebrates that can fly, and a skunk’s anal glands are used to spray a foul odor at attackers. A second correct answer would be that elephants, as mammals, have two pairs of mammary glands.
Those who chose the first correct answer would also be correct in guessing that the third correct answer is that a skunk’s anal glands are used to spray a foul odor at attackers. The first answer was incorrect because vertebrates include many creatures with wings: bats, flying squirrels, and pterosaurs. The second incorrect answer was incorrect because mammals contain many creatures with one pair of mammary glands: bears and humans. The third incorrect answer was incorrect because only insects have anal glands (fungus-dwelling arthropods) and both mammals and birds have two pairs of mammary glands.
There are many misconceptions about animals, just as there are about people’s personal characteristics or medical conditions. In an attempt to change the question into an attempt to explain animals, the question was changed to “Which of these is unique to animals?”, which sounds more like a biological question rather than a questionnaire. This may have been intended as a subtle way of getting rid of the “birds fly” and “elephant has only one pair of mammary glands” answers.
There were also attempts to make this thing about animals, but it wasn’t all that successful because it was a website devoted to reporting news; journalists, who are tasked with trying to make their work sound more interesting than it is, sometimes forget that journalism is supposed to be fun as well as informative.
Even though the writers of the quiz weren’t intending to be cute, they were nevertheless trying to be accurate. Of the actual correct answers, two of them are biologically incorrect: “birds fly” is only a special case of “vertebrates”, and only mammals have two pairs of mammary glands.
The first sentence of this article is not about animals (because it doesn’t follow any “animal” theme). The second sentence isn’t about animals either. The third sentence is about animals, though it does talk about some humans. But it’s a small part of the article. The fourth sentence is about animals too. So is the sixth sentence. So is the seventh sentence, which talks about “anthropomorphising”. The eighth sentence talks about ordinary, non-animal things.
It’s not a very good article, but it’s not about animals either; it’s just a listing of things that happen to be true about animals.
The nine sentences are all by themselves and they’re all talking to each other; they’re all different kinds of claims reporting on facts and events that are not as they seem after you know those nine facts. The next sentence reports on a fact about animals that does not seem to be true after you know those nine facts.
The next four sentences are about other people, and they’re all really different kinds of claims (e.g., before, during, and after the First World War) reporting on facts and events that are not as they seem after you know those four facts.
The next three sentences are about things that do not happen in the real world: “fountain pens”, “Vernor Vinge”, and “Hollywood”. The next two sentences are about animals: the tortoise and the painted turtle. But the rest of the article is not about animals; it’s about people.
Further, animals don’t write articles that talk about themselves; they aren’t authors. And a tortoise isn’t a person either, even if it is named “Tortoise”.
The title was an attempt to summarize what the article was about (in this case, it wasn’t very successful), but was not actually true as explained above. The actual title of this article is “Pope Francis” by Ljubivoje Dejanović of Belgrade, Serbia, which can be verified here: http://en.wikipedia.
