1. which sentence uses the word stance properly?

a. what is josie's stance on the required school uniforms?
b. if you stance over there i can see you better.
c. jerome was stance in his beliefs about his religion.
d. hang your coat on the stance.

2. read the sentence:
dan is a great coach he motivates the girls in a positive way.

which correctly states the punctuation needed in the blank?

a. comma
b. semicolon
c. period
d. no punctuation needed.

Your answers would be: 
1. A. What is Josie's stance on required school uniforms?

2. B. Semicolon
Because: 
semicolons seperate two things
commas are usually used with and or for a list in sentence form, not list form... for example: Josie is a smart, funny, and friendly girl. (only thing I could think of) instead of: 
Josie's qualities are: 
1. Smart
2. Funny
3. Friendly
period is after a sentence, and if you put a period there, it will be: Dan is a great coach. He motivates the girls in a positive way, and will make both those sentences incomplete or fragments... 
no punctuation needed wouldn't be correct because it will say: Dan is a great coach he motivates the girls in a positive way (that makes no sense)
