Read the following passage carefully.

We sat in silence in the dark of the night as the large head appeared from the large foliage. The female, was young, healthy and alert. Seconds later, she walked confidently to the edge of a waterhole followed by not one, not two, but three beautiful young cubs. Like works of art on display, all four tigers bent low at the waterhole that had been created for them and for the myriad creatures that shared their troubled kingdom. The Goshri tigers had come visiting and we watched them with rapt attention on our closed-circuit TV screens, in the conservation retreat of Harsh and Poonam Dhanwatey, a husband and wife team whose life had been dedicated to the protection of tigers in and around Maharashtra’s Tadoba-Andhari Tiger Reserve. Their son Nikhil carefully positioned the cameras and cabled them 40 metres from their conservation retreat, near the waterhole that had turned into a magnet for every conceivable animal found in the Tiger Reserve itself. We were making preparations to set up one of the first Community Conservation Reserves in Central India. Originally into business, the Dhanwatevs changed tracks midstream by shutting down a thriving interior design business in response to just one meeting they had with Dr. Ullas Karanth and Valmik Thapar, two of India’s finest tiger people, in Nagpur. In their own words: “From admirers of wildlife we became passionate defenders and we launched our non-governmental organization called Tiger Research and Conservation Trust (TRACT).” The Dhanwatevs lived for years in a small hut that was their field camp near the famous Tadoba Lake and they discovered the secrets of the forest in the best way possible, by walking its trails, and generally learning all they could about the magical mix of life that comprised this tropical, dry deciduous forest.

Read the following passage carefully.

“Mum!” I shouted. “Are you okay?” I saw her little tent shuddering in the gale and listened closely for her response. Her voice was almost casual: “Oh, yes, I’m fine.” That’s my mother. It was the first night of our cycling trip through the interior of Iceland—a region so remote and inhospitable that for centuries, according to legend, it was abandoned. The weather was decidedly hurricane-like, but Mum wasn’t concerned. Months ago, I told her about my plan to pedal across Iceland. “It will be really difficult,” I said. “The roads are unpaved and often washed out, and the wind is blowing constantly — sometimes so hard that it pushes you off the road.” There was silence for a moment. Then she asked, “Can I come?” “Sure,” I replied. “But like the rest of us, you have to train to do two 160 kilometres a day back-to-back,” “Wow,” she said, “I could never do that.” I had more faith in my mother’s physical abilities than she did. I’d seen her raise six children and put in long hours doing physical labour on our small farm. “Sure you can,” I told her, “Start tomorrow.” What really concerned me was what 1 perceived to be her frustrating humility: I thought her too self-depreciating about her intellect just because she had not completed college. 1 felt she underestimated her attractiveness just because she was not the type to wear makeup or fancy clothes. As I had grown into adulthood, the life I’d chosen seemed light-years away from Mum’s quiet existence, still caring for her children and her children’s children. Sometimes, on a visit home, I’d describe some recent trip I’d taken, and her blue eyes would shine with interest. So I couldn’t help thinking this trek might revitalize Mum, who had started to slow down in her 50s. It might spice up what I saw as her humdrum life. And it might be a boost to her tentative and retiring persona. Mum trained furiously, months in advance. As the trip roster was pared down to Mum, my good friend Allen and me, she stood as the most dedicated. Soon she was riding 80-100 kilometres per day, and was as strong a rider as Allen or I.

On the basis of your reading of the passage, answer the following questions briefly:
