Question : If $a+\frac{1}{a}=3$, then the value of $a^4+\frac{1}{a^4}$ is:
Option 1: 48
Option 2: 81
Option 3: 27
Option 4: 47
Correct Answer: 47
Solution : Given, $(a + \frac{1}{a})$ = 3 Squaring both sides, we get, $(a + \frac{1}{a})^2 = (3)^2$ ⇒ $a^2 + \frac{1}{a^2} + 2 = 9$ ⇒ $a^2 + \frac{1}{a^2} = 7$ Squaring both sides, ⇒ $a^4 + \frac{1}{a^4} + 2 = 49$ $\therefore a^4 + \frac{1}{a^4}$

Question : Comprehension:
Read the following passage and answer the questions.
This year, I celebrated twenty-five years with a Seeing Eye dog. When I came to "The Seeing Eye' in 1983, I had no idea how much my canine partner would do for me. I can well remember walking down a country road independently, with a light step and joy in my heart, knowing that Novel- my first Seeing Eye dog- would keep me safe.
Since that glorious beginning, my dogs have seen me through two university degrees while living in four different cities in Canada and the United States. These competent and loving guides have shown me amazing skills - keeping me safe from traffic, fallen trees, new places and a host of unseen dangers. I have acquired self-confidence and a faith that anything is possible with my dog at my side. Over the years, my dogs have always been a source of pride and pleasure for me, and I brag about them to my family and friends.
Today, the way young Rambo manoeuvres me through the rush-hour traffic is wonderful. But it is all those little things like finding a table at a restaurant, finding empty cubicles at the physical therapy clinic where I work, that can mean so much more. Rambo is my sixth guide who arrived in June 2008 after Ruskin left me. He has already established himself in my heart. He is guiding me through another chapter in my life. I wish to thank all my friends at 'The Seeing Eye' for the support they have offered me over the years. I also thank them for being like family, most importantly, being there to train these furry soul-mates so well!
