Answer:
1. Correctly punctuated sentence:
John announced, "The library is closing in five minutes."
2. Correctly capitalized sentence:
I walked home with Kate.
3. Correctly written sentence:
My favorite stores are Bloomingdale's and Macy's.
My sister only shops at Nordstrom.
Explanation:
By putting the actual announcement made by John in quotation marks, John's direct speech is accurately reported verbatim.
For the second sentence, the words to capitalize are the "I" and the name "Kate." "I" and "Kate" are always capitalized because 'I" cannot be written otherwise and "Kate" is the name of a person or a proper noun, which grammatically must be capitalized.
The apostrophe before s in Bloomingdale's and Macy's shows possession. This means that the two stores are owned by the families of Bloomingdale and Macy. Nordstrom does not have an "s."
