Passage 1

Imagine a world in which there was suddenly no emotion--a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive; knowing neither joy nor pleasure, neither anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionless world would lack rewards and punishments. Society would soon disappear: people would be as likely to harm one another as to provide help and support. Human relationships would not exist: in a world without friends or enemies, there could be no marriage, affection among companions, or bonds among members of groups. Society’s economic underpinnings would be destroyed: since earning $10 million would be no more pleasant than earning $10, there would be no incentive to work.
A. they would not be able to tell the texture of objects
B. they would not know what was beneficial and what was harmful to them
C. they would not be happy with a life without love
D. they would not know how to protect themselves and not to hurt each other
