Instruction: Read the following passage carefully and answer the questions,Q (1 to 4):
Active primarily at night, and at dusk and dawn, muskrats nonetheless may be seen at any time of day in all seasons, especially spring. Excellent swimmers, these aquatic rodents spend much of their rudder like tail for guidance, they can swim backward or forward with ease. They dislike strong currents and avoid rocky areas. Their mouths close behind protruding incisors, thus allowing them to chew underwater. They can remain submerged for long period, traveling great distance underwater. One muskrat was filmed underwater for 17 minutes, coming to the surface for air for 3 seconds, then submerging for another 10 minutes.
Their large house commonly contain one nesting chamber with one or more underwater entrance. Houses constructed along banks may have several chambers, each with one or, more tunnels leading underwater. The houses and feeding platforms are added to as long as they are used; they usually house only one individual, though several muskrats may live together harmoniously. Food is commonly towed out to the feeding platforms, which can be distinguished from the house by plant cuttings and other scattered debris form eating. Houses are kept immaculately clean, with litter deposited on logs and rocks outside. Droughts and flooding are common hazards faced by these rodents, causing periodic population fluctuations. Overcrowding, especially when it occurs during fall or winter, causes fighting among individuals, forcing many to travel several miles overland to seek a new place to live.
(Q-3): How can one tell the difference between muskrat houses and feeding platforms?
