You're signed up for Rec Ball. You don't like it and you're not very good at playing. But your dad asks you to stick with it, saying you'll get better and will like it more if you keep trying. What do you do? 3 to 5 sentences

I would continue the sport for a while longer to see if I find it enjoyable, after a while, if I don't seem to enjoy it after trying, I would explain to my father that I do not wish to continue the sport and do not find it very enjoyable.  I would also suggest that I could start another hobby of my interest.  Another Idea is to try and persuade the father to let you try another sport that you find more to your liking.  

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
