A. Your grandparents’ house/ theirs
The sentence which uses possessive personal pronouns correctly is sentence (d).<span>Did you eat the whole potato and its skin?
the rest of the sentences should've been written like this:
</span><span>Alicia thought that the blue jacket was hers.
</span><span>The dolphin bobbed its head up and down.
</span><span>Yours was the one with the blue tag, on the table.</span>
<span>The sentence that best illustrates President Roosevelt's speech is A. Roosevelt is saying he will provide us with resources so on the other hand we will be prepared to win. He will provide the essentials and more so to complete and defend the United States.</span>
There is only one sentence which needs a semicolon added to be correct, and that is <span>5) Water is not everywhere it's miles away.
As you can see, the way this sentence is written, something seems wrong - words are just mixed around incoherently. This is why we need a semicolon to make things more accurate: Water is not everywhere; it's miles away. </span>
