1. The word that personifies the image of the stars is c) shiver. Personification is an attribution of human qualities to non-human beings or things. In this case, the stars shiver, as if they were human beings. "Starry" is an adjective that doesn't add any human quality, and it pertains to the night, not the stars. "Blue" is also a regular adjective that describes the color of the stars. "Sings" is a verb that personifies the night wind, not the stars.
2. The poet personifies each of the following except the a) sky. He personifies the heart ("My heart looks for her"), the soul ("My soul is not satisfied that it has lost her"), and the voice ("My voice tried to find the wind").

3. If the options are: <span>A) Tonight I can write the saddest lines; B) Through nights like this I held her in my arms; C) She loved me, sometimes I loved her too; D) Love is so short, forgetting is so long, the answer is D) Love is so short, forgetting is so long. This is a unique thought that can be regarded as the main source of his anguish. He remembers all the nights like that one when they were together. Those nights constitute the long (possibly endless) process of forgetting, while their love was so short. That is why he is so much in pain - because he can't forget her. It creates the new meaning of love. It is not the very process of exercising love. It is the impossibility of forgetting one's beloved.</span>
