Which of the following is a metaphor?
a) my heart is stone
b) my heart is as heavy as a stone
c) my heart is like a stone fallen to the bottom of a pond

The answer is A. A metaphor is comparing something with something else. Unlike a simile, it doesn't have the word "like" or "as". I hope this helped! :-)

i cannot see a paragraph to answer the question

the narrator is a first person, participant one, who describes in the simple past tense important and difficult events in his earlier life. he also provides temporal markers as the month (january) and the time (12: 30 pm). finally the account of his experience is very detailed, to the extent that a participant narrator would talk the same way about his experiences. a good example of such detail is the mention of the “bovril ration” which historically was a native american food adopted by european explorers in arctic and antarctic regions due to its high level of calories.
