Hello. You did not present the passage to which this question refers, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.
I believe that with "similar" you meant "simile" in the question above. Well, unfortunately, it is only possible to identify the line that presents the simile with the reading of the passage. However, it is very easy to recognize a simile, because this is a figure of speech that establishes a comparison between two elements that are not directly related to each other, but that can be related subjectively. In addition, sentences that have simile have the words "like" and "as" to make the comparison.
An example of simile can be seen in the phrase "they are eyes are blue like the sky in the summer." The words "sky" and "eyes" have no direct relationship, but through simile they can be related by a characteristic that is the color blue.
