Prepare a summary of the extract given in Q. 2 (A). Give it a suitable title. You may use the following points :

Luxurious houses in nature – fear of wild animals – leopards enjoy human habitation – provide food

Read the extract and complete the activities given below :

    Luxurious houses on the edge of a big city which one promoter sold with the tagline ‘‘Where Nature peeps through every window.’’ All the advantages of a modern lifestyle but with the added bonus of fresh air. But nature isn’t greenery alone; it also includes wild animals.
   While the view from the picture windows was easy on the eye, occasionally, it made them gulp with nervousness. At dusk, wild cats leaped out of the adjoining forest on to the top of the peripheral walls and strolled nonchalantly. Sometimes, they lounged on ledges with their long tails swinging freely, oblivious of the many worried human eyes pinned on them. Their cold yellow aggressive eyes turned black as their pupils dilated with failing light.
   Some Mumbaikars paid a lot of money to see leopards on safari in Africa. But to watch them from one’s own home was disconcerting. These predators were out of line, stepping off nature into the city. Why did the leopards not stay within the 100-square kilometre Sanjay Gandhi National Park? Perhaps, the leopards thought that if people could venture into nature to jog, walk and picnic, why couldn’t they hang around apartment blocks? If people could enjoy nature, couldn’t nature savour humanity’s offerings?
   Capturing leopards is extraordinarily simple. These curious cats seem incapable of resisting a free meal, walking into baited traps without hesitation. The reason the felines are attracted to their residential community is prey : stray dogs that live on rubbish heaps. Taking care of the food source is the best course of action, the volunteers said.
