Passage for Reading & Comprehension: "Father, there is no college in our village or any other village around ours. The only college where I can go is 50 miles away, in the city. It seems impossible that I can continue my studies although I had dreamed that I would become a doctor and open a hospital here for the villagers, as they cannot afford to go to the city hospital. Remember, how Uncle Sarmad died last year only because he could not be taken to the hospital on time?" Jameel said.

His mother quoted a Sindhi couplet which meant 'Where there is a will there is a way. Distances are to be covered.' She then said, "We can ask Allah Bachayo, to take you to the city in his horse cart."

Aunt Sadori, who had been listening to the whole conversation said, "I have a suggestion. You people have done so much for me, I think now it's my turn to return the favour. Jameel and Sara can easily come and live with me in the city and study in the college."

"Really! Can I really go and study in the city?" Sara exclaimed.

"Jameel can go but Sara should stay here and help her mother," said father.

Sara quickly wiped the tear that had rolled down her cheek. She didn't want her father to know her feelings. However, Khalid noticed her emotions and said, "Father, don't worry about the expenses. Let both of them go."
