1. Liz"s textbook - The correct option is "Liz"s textbook." The possessive case is used to show ownership or belonging. In this case, it is indicating that the textbook belongs to Liz.

2. the house"s roof - The correct option is "the house"s roof." Here, we are indicating that the roof belongs to the house. By adding an apostrophe followed by an "s" ("s) to the noun "house," we form the possessive case.

3. the rabbits" cage - The correct option is "the rabbits" cage." In this case, we are indicating that the cage belongs to multiple rabbits. As the noun "rabbits" is already plural, we only add an apostrophe (") after the final "s" to show possession.

4. The Smiths" car - The correct option is "The Smiths" car." Here, we are indicating that the car belongs to the Smith family. Since the noun "Smiths" is already plural, we add an apostrophe (") after the final "s" to show possession.

5. Charles" book - The correct option is "Charles" book." In this case, we are showing that the book belongs to Charles. As the name "Charles" already ends with an "s," we only add an apostrophe (") after the final "s" to indicate possession.

6. a bird"s nest - The correct option is "a bird"s nest." Here, we are indicating that the nest belongs to a bird. By adding an apostrophe followed by an "s" ("s) to the noun "bird," we form the possessive case.

7. those men"s umbrellas - The correct option is "those men"s umbrellas." In this case, we are indicating that the umbrellas belong to the group of men. Since the noun "men" is already plural, we add an apostrophe (") after the final "s" to show possession.

Remember, in English, the possessive case is used to indicate ownership, and we form it by adding an apostrophe followed by an "s" ("s) to the noun. However, if the noun is already plural and ends with an "s," we only add an apostrophe (") after the final "s."
