Answer:
(p.5) the imagry of what it is saying is that how many people are afraid of firemen but it seems as if they realized that the man is just a man after all. As if that person was afraid of the man but they now know that, that man is like any other type man. the effect of it was that the reader comprended that it's just a regular type of man, nothing else. As firemen are more prepared and organized, the man that was described as "But you're just a man, after all." is nothing compared to the firemen.
(p.15) the imagery is the toaster because it said "the toaster spidered out" as if saying the buttered bread is ready for him. it created an image for the reader on how it was done with the buttered bread.
