Answer:
<em>"The old man stumbled like a broken record, his grin a grainy tune"</em>
Explanation:
A Simile, by dictionary definition, is a figure of speech involving the comparison of one thing with another thing, whereas a Metaphor is a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable. For example:
"<em>Her heart is </em><em>like</em><em> gold"</em>
<em>"Her heart </em><em>is </em><em>gold"</em>
Here, the former is a simile, and the latter is a metaphor. In the first one, we are <em>comparing</em> the girl's heart to gold, and in the second, we state that her heart <em>is</em> gold.
Taking the original sentence: <em>"The old man stumbled".</em>
And then my answer sentence: "<em>The old man stumbled like a broken record, his gravely grin a grainy tune".</em>
Here, the words "...stumbled like a broken record" is the token simile. We can see this with the key words "like and as"
The metaphor in the sentence is the way I described his smile. Comparing it to an object or thing that can't literally make sense—the grainy tunes of an old record player.
