Passage
Read the following passage and answer the given subquestions.
With the opening of that sack began a phase of my life that has not yet ended, and may, for all I know, not end before I do. It is, in effect, a thraldom to otters, an otter fixation, that I have since found to be shared by most other people, who have ever owned one. The creature that emerged from this sack on to the spacious tiled floor of the Consulate bedroom resembled most of all a very small, medievally-conceived, dragon. From the head to the tip of the tail he was coated with symmetrical pointed scales of mud armour, between whose tips was visible a soft velvet fur like that of a chocolate-brown mole. He shook himself, and I half expected a cloud of dust, but in fact it was not for another month that I managed to remove the last of the mud and see the otter, as it were, in his true colours. Mijbil, as I called the otter, was, in fact, of a race previously unknown to science, and was at length christened by zoologists Lutrogale perspicillata maxwelli, or Maxwell’s otter.
For the first twenty-four hours Mijbil was neither hostile nor friendly; he was simply aloof and indifferent, choosing to sleep on the floor as far from my bed as possible. The second night Mijbil came on to my bed in the small hours and remained asleep in the crook of my knees until the servant brought tea in the morning, and during the day he began to lose his apathy and take a keen, much too keen, interest in his surroundings. I made a body-belt for him and took him on a lead to the bathroom, where for half an hour he went wild with joy in the water, plunging and rolling in it, shooting up and down the length of the bathtub underwater, and making enough slosh and splash for a hippo. This, I was to learn, is a characteristic of otters; every drop of water must be, so to speak, extended and spread about the place; a bowl must at once be overturned, or, if it will not be overturned, be sat in and splashed in until it overflows. Water must be kept on the move and made to do things; when static it is wasted and provoking.
Two days later, Mijbil escaped from my bedroom as I entered it, and I turned to see his tail disappearing round the bend of the corridor that led to the bathroom. By the time I got there he was up on the end of the bathtub and fumbling at the chromium taps with his paws. I watched, amazed; in less than a minute he had turned the tap far enough to produce a trickle of water, and after a moment or two achieved the full flow. (He had been lucky to turn the tap the right way; on later occasions he would sometimes screw it up still tighter, chittering with irritation and disappointment at the tap’s failure to cooperate.) Very soon Mij would follow me without a lead and come to me when I called his name. He spent most of his time in play. He spent hours shuffling a rubber ball round the room like a four-footed soccer player using all four feet to dribble the ball, and he could also throw it, with a powerful flick of the neck, to a surprising height and distance. But the real play of an otter is when he lies on his back and juggles with small objects between his paws. Marbles were Mij’s favourite toys for this pastime: he would lie on his back rolling two or more of them up and down his wide, flat belly without ever dropping one to the floor.
