In 1-2 sentences, explain how to use an apostrophe to show possession for singular and plural nouns and to form contractions. (2 points)
To show possession for singular nouns, add an apostrophe followed by "s" (e.g., The dog's bone). For plural nouns, add an apostrophe after the "s" (e.g., The dogs' bones). To form contractions, use an apostrophe to replace letters in a word combination (e.g., can't for can not).
Write three sentences, each using a comma in a different way. Explain why the comma is needed in each sentence.
1. "I went to the store, and bought some bread." The comma is needed here in order to separate two independent clauses joined by the coordinating conjunction "and."
2. "She loves to read books, watch movies, and listen to music." The comma is necessary to separate items in a list (also known as a series).
3. "After finishing her homework, Sarah went outside to play." In this case, the comma is needed to set off an introductory phrase ("After finishing her homework") from the main clause.
