What excited Mrs. Sommers the most about her plans?

Read the given passage and answer the four questions that follow:-

Little Mrs. Sommers one day found herself the unexpected possessor of fifteen dollars. It seemed to her a very large amount of money, and the way in which it stuffed and bulged her worn old porte-monnaie (purse) gave her a feeling of importance such as she had not enjoyed for years.

The question of investment was one that occupied her greatly. For a day or two she walked about apparently in a dreamy state, but really absorbed in speculation and calculation. She did not wish to act hastily, to do anything she might afterward regret.

But it was during the still hours of the night that she seemed to see her way clearly toward a proper and judicious use of the money. A dollar or two should be added to the price usually paid for Janie's shoes, which would ensure their lasting an appreciable time longer than they usually did.

She would buy so and so many yards of percale for new shirt waists for the boys and Janie and Mag. Mag should have another gown. She had seen some beautiful patterns, veritable bargains in the shop windows. And still there would be left enough for new stockings-two pairs apiece-and what darning that would save for a while! She would get caps for the boys and sailor- hats for the girls. The vision of her little brood looking fresh and dainty and new for once in their lives excited her and made her restless and wakeful with anticipation.
