Answer:
Your answer would be that the literary device used in the passage is an analogy.
Explanation:
In the passage above, the author has used the literary device called analogy. An analogy is a comparison in which a thing or an idea is compared to another thing which is a little different from it. Its purpose is to explain the original idea by comparing it to something that is familiar. In this case, a relationship is compared to the way the stock market works. The author explains that both of them have ups and downs and that, in both cases, you only get what you put into them.
It is used in several contexts, one of them is "stark naked", when it is used like "naked as a jaybird", or in this case, when someone needs to take a shower, or change their clothes because she or he is scruffy, dirty or smelly, You may hear "go change your clothes, you are ragged as a jaybird", the color of the bird gives an appearance of dirt that is related to the popular saying.
I'm guessing "would you prefer tuna fish or roast beef on your sandwich" because subjective is based on or influenced by personal feelings, taste, or opinion
