the answer to 2 is C, because there is a metaphor because Mikayla's computer aren't really dinosaurs. A metaphor is more like an exaggeration to make a point. But there is also a simile in here, when it says that the printer is as slow as a sloth. A simile is something that is made the same with the use of a word "like" or "as". Making a parallelism.
The answer to 2 is D, because there are no figures of speech. There is nothing that uses "like" or "as" to be described, and there is no "Untrue" thing that exaggerates :)
Does this make sense?
If not, don't hesitate to message me or ask me more questions, ok?
