Hope you are doing fine and enjoying the season. I am so happy that you asked me to babysit Anna for you. She is such an adorable child and I love spending time with her. I would be happy to babysit her for you but due to my exam at the university the next Monday, I am afraid I cannot spare time on Saturday. However, I will be free the next week and would be happy to look after her if you want.

I will be horribly busy studying this whole week and during the weekends as I have an important exam next Monday. My term final result will depend on this exam and I have to dedicate my time to prepare for it. I hope you understand that I cannot spare time before my exam even after I wish I could. However, I will be free the next weekend and would like to babysit for you in case you go out then.

As I remember, I charged you 20 dollars an hour last time and the charge would be the same this time as well. In case you need my service for more than 8 hours a day, you should inform me beforehand.

With lots of love.

Yours truly,

Emma

Read the passage carefully and then answer the questions below 

           Becky schroeder, glo-sheet

Becky was only 10 years old when she was attempting to do homework in her mom car. As it got darker outside, she had the idea that there should be a way to make her paper easier to see in the dark. Becky took matters into her own hands and began playing around with phosphorescent materials, which emitted light but without heat. She then used phosphorescent paint to cover an acrylic board and the Glow-Sheet was created. In 1974, at the age of 12, Becky became the youngest women to be granted U. S. patent for her Glo-Sheet invention.
