Then re-think and let us know what you decide.

To identify which sentence features a possessive noun, we need to understand what a possessive noun is. A possessive noun shows ownership or possession of something. It is formed by adding an apostrophe ('s) followed by an 's' to singular nouns, or just an apostrophe (') for plural nouns ending in 's'.

Let's analyze each sentence:

1. "Everything I know about gardening I learned from my good friend Sandy."
In this sentence, there is no possessive noun.

5. "When she showed me her big, healthy vegetable garden and offered me some gardening tips, I decided to listen hard."
This sentence contains the possessive noun "her," which expresses ownership of the vegetable garden.

7. "Then she taught me how to cultivate rich and healthy soil and helped me identify which types of plants are best for the environment in my yard."
This sentence does not have a possessive noun.

11. "My dream is that one day my garden will be just as beautiful and productive as Sandy’s!"
This sentence features the possessive noun "Sandy's," indicating ownership of the beautiful and productive garden.

Based on this analysis, the correct answer is sentence 11: "My dream is that one day my garden will be just as beautiful and productive as Sandy’s!"
