Q. Read the passage and answer the question that follows.
An elm in our backyard caught the blight this summer and dropped stone dead, leafless, almost overnight. One weekend it was a normal-looking elm, maybe a little bare in spots but nothing alarming, and the next weekend it was gone, passed over, departed, taken....
The dying of a field mouse, at the jaws of an amiable household cat, is a spectacle I have beheld many times. It used to make me wince.... Nature, I thought, was an abomination.
Recently I’ve done some thinking about that mouse, and I wonder if his dying is necessarily all that different from the passing of our elm. The main difference, if there is one, would be in the matter of pain. I do not believe that an elm tree has pain receptors, and even so, the blight seems to me a relatively painless way to go. But the mouse dangling tail down from the teeth of a grey cat is something else again, with pain beyond bearing, you’d think, all over his small body. There are now some plausible reasons for thinking it is not like that at all.... At the instant of being trapped and penetrated by teeth, peptide hormones are released by cells in the hypothalamus and the pituitary gland; instantly these substances, called endorphins, are attached to the surfaces of other cells responsible for pain perception; the hormones have the pharmacologic properties of opium; there is no pain. Thus it is that the mouse seems always to dangle so languidly from the jaws, lies there so quietly when dropped, dies of his injuries without a struggle. If a mouse could shrug, he’d shrug....
Pain is useful for avoidance, for getting away when there’s time to get away, but when it is end game, and no way back, pain is likely to be turned off, and the mechanisms for this are wonderfully precise and quick. If I had to design an ecosystem in which creatures had to live off each other and in which dying was an indispensable part of living, I could not think of a better way to manage.
Which of the following would best characterize the author’s attitude toward the relationship between pain and death?
