I don't know why UFOs are never sighted over large cities by hordes of people. But it is consistent with the idea that there are no space vehicles from elsewhere in our skies. I suppose it is also consistent with the ideas that space vehicles from elsewhere avoid large cities. However, the primary argument against recent extraterrestrial visitation is the absence of evidence.
Take leprechauns. Suppose there are frequent reports of leprechauns. Because I myself am emotionally predisposed in favor of leprechauns, I would want to check the evidence especially carefully. Suppose I find that 500 picnickers independently saw a green blur in the forest. Terrific. But so what？ This is evidence only for a green blur. Maybe it was a fast hummingbird. Such cases are reliable but not particularly interesting.
Now suppose that someone reports: "I was walking through the forest and came upon a convention of 7000 leprechauns. We talked for a while and I was taken down into their hole in the ground and shown pots of gold and feathered green hats. "I will reply: "Fabulous! Who else went along？" And he will say, "Nobody", or "My fishing partner". This is a case that is interesting but unreliable. In a case of such importance, the uncorroborated testimony of one or two people is almost worthless. What I want is for the 500 picnickers to come upon the 7000 leprechauns.., or vice versa.
The situation is the same with UFOs. The reliable cases are uninteresting and the interesting cases are unreliable. Unfortunately, there are no cases that are both reliable and interesting.
What's the author's attitude towards the UFOs？
A．The author is not sure whether they are true or not.
B．The author doubts if they are true.
C．The author doesn't think they are interesting.
D．The author simply does not believe them.

As many of the stories in this book are about man-eating tigers, it is perhaps (1)_____ to explain why those animals (2)_____ man-eating tendencies. A man-eating tiger is a tiger that has been compelled, through stress of circumstances beyond its (3)_____ to adopt a diet alien to it. The stress of circumstances is, in nine cases out of ten, wounds, and in the tenth case old age. The wound that has caused (4)_____ tiger to take up man-eating might be the result of a carelessly fired (5)_____ and failure to follow up and (6)_____ the wounded animal, or be the result Of the tiger having lost its temper when killing a porcupine. Human beings are not the natural prey of tigers, and it is only when tigers have been (7)_____ through wounds or old age that, in order to live, they are compelled to a diet of human flesh. They can no longer make a (8)_____ of animal in (9)_____ A tiger uses its teeth and claws when killing. When, therefore, a tiger is suffering (10)_____ one or more painful wounds, or when its teeth are, missing or defective and its claws (11)_____ down, and it is unable to catch the animals it has been accustomed to eating, it is (12)_____ by necessity to killing human beings. The (13)_____ from animal to human flesh is, I believe, in most cases accidental. As (14)_____ of what I mean by "accidental" I quote the case of the Muktesar man-eating tigers. This tigress, a comparatively young animal, in (15)_____ with a porcupine lost an eye and got some fifty quills, (16)_____ in length from one to nine inches, embedded under the (17)_____ of her right foreleg. Suppurating (18)_____ formed where she endeavoured to extract the quills with her teeth, and while she was lying up in a thick (19)_____ of grass, starving and licking her wounds, a woman selected this particular place to cut the grass as fodder for her cattle. At first the tigress took no notice, but when the woman had cut the grass right up to where she was lying the tigress struck once, the blow (20)_____ in the woman's skull.
A．wishful
B．desirable
C．required
D．needed
