Answer:
Simile and personification, explanations below!
Step-by-step explanation:
"Like the straw in her pink lemonade" = simile
A simile compares two things using like or as. In this case, the story compares the bending of the microphone to bending the straw in lemonade.
"Her voice an impostor" = personification
Personification describes a object with human-like qualities or characteristics. In this case, a voice can't actually be an impostor as it is not a living person.
