It’s going to cost fifteen dollars and I have to take the money tomorrow, otherwise it’ll be given to someone else.” The last words came out in an eager rush. Grandpa straightened up tiredly and leaned his chin on the handle. He looked over the field that was filled with the tiny green bean plants. I waited, desperately hoping he’d say I could have the money. He turned to me and asked quietly, “What does a scholarship jacket mean?”

A) It is hard work for Grandpa to keep up with the bean fields.

B) Grandpa cannot afford to give Martha the money for the jacket.

C) It is very hard for Martha to communicate with Grandpa because he only knows Spanish.

D) Martha finding the courage to ask her grandfather to pay for the scholarship jacket.
