Answer:
Rhyme & Imagination
Step-by-step explanation:
Rhetorical features are generally used to persuade or impress the audience.
The impact of a short and thoughtful phrase can do the trick, even more so when there is rhyme involved.
¨Empathy can´t be taught, but it can be caught¨ is such a phrase because there is rhyme, but moreover there is the powerful visualisation (and imagination) of Empathy as something concrete that you can catch, if you open your eyes and just...watch.
