Answer and Explanation:
Ovid managed to generate suspense in "Pyramus and Thisbe" from the beginning of the narrative, when only young people communicate through a small space between their homes, and they can be discovered at any time by someone who would prevent them from being together. However, the high point of the suspense is portrayed at the end of the poem, when Ovid causes Pyramus to find his beloved's bloody vein and is extremely sad, making the reader unable to know what he will actually do, until he decides he needs to die. Furthermore, the suspense gets even greater when Thisbe finds her beloved dead and decides to have the same end.
An unreliable narrator is a narrator that cannot be trusted because his/her version of the story isn´t completely correct for various reasons, such as his/her mental state or the fact that s/he may not be objective.
The best example of an unreliable narrator is one who narrates the story from a first person perspective. Sometimes the readers know it from the very start of the story that the narrator is unreliable while other times this is revealed gradually throughout the story or even at the end of the story.
