English PARA QUE UNIT [4M]

When the walking tour was done, I rushed to a phone booth and, almost tearing the cord so it could reach me outside, phoned Stephen Hawking's house. There was his assistant on the line and I told him I had come in a wheelchair from India (perhaps he thought I had propelled myself all the way) to write about my travels in Britain. I had to see Professor Hawking-even ten minutes would do. "Half an hour," he said. "From three-thirty to four."
And suddenly I felt weak all over. Growing up disabled, you get fed up with people asking you to be brave, as if you have a courage account on which you are too lazy to draw a cheque. The only thing that makes you stronger is seeing somebody like you, achieving something huge. Then you know how much is possible and you reach out further than you ever thought you could.
Questions:
(1) I rushed to a phone booth and, almost tearing the cord so it could reach me outside, phoned Stephen Hawking's house. What kind of the writer's feeling do these underlined words show?
(2) Why had the writer come all the way from India?
(3) Why did the writer feel weak all over?
(4) What makes a disabled stronger, according to the writer?

"What do you think is the best thing about being disabled?" I had asked him earlier. "I don't think there is anything good about being disabled."
"I think." I said, "you do discover how much kindness there is in the world."
"Yes," he said: it was a disadvantage of his voice synthesiser that it could convey no inflection, no shades or tone. And I could not tell how enthusiastically he agreed with me.
Every time I shifted in my chair or turned my wrist to watch the time - I wanted to make every one of our thirty minutes count-I felt a huge relief and exhilaration in the possibilities of my body. How little it mattered then that I would never walk, or even stand.
Questions:
(1) What was the reply from Stephen Hawking for the best thing about being disabled'?
(2) Why could the writer not tell the intensity of Stephen Hawking's enthusiasm in replying his question ?
(3) Why did the writer look at his watch every now and then?
(4) What was the writer's feeling in the end ?

"Is there any advice you can give disabled people, something that might help make life better?"
"They should concentrate on what they are good at; I think things like the disabled Olympics are a waste of time."
"I know what you mean." I remembered the years I'd spent trying to play a Spanish guitar considerably larger than I was; and how gleefully I had unstringed it one night. The half-hour was up. "I think I've annoyed you enough," I said, grinning. "Thank you for ..." "Stay." I wai "Have some tea. I can show you the garden."
The garden was as big as a park, but Stephen Hawking covered every inch, rumbling along in his motorised wheelchair while I dodged to keep out of the way. We couldn't talk very much; the sun made him silent, the letters on his screen disappearing in the glare.
