The practice of capital punishment is as old as government itself. For most of history, it has not been considered controversial. Since ancient times most governments have punished a wide variety of crimes by death and have conducted executions as a routine part of the administration of criminal law. However, in the mid-18th century, social critics in Europe began to emphasize the worth of the individual and to criticize government practices they considered unjust, including capital punishment. The controversy and debate over whether governments should utilize the death penalty continue today.
The first significant movement to abolish the death penalty began during the era known as the Age of Enlightenment. In 1764 Italian jurist and philosopher Cesare Becearia published an essay on Crimes and Punishments. Many consider this influential work the leading document in the early campaign against capital punishment. Other individuals who campaigned against executions during this period include French authors Voltaire and Denis Diderot, British philosophers David Hume and Adam Smith, and political theorist Thomas Paine in the United States.
Critics of capital punishment argue that it is cruel and inhumane, while supporters consider it a necessary form. of revenge for terrible crimes. Those who advocate the death penalty declare that it is a uniquely effective punishment that prevents crime. However, advocates and opponents of the death penalty dispute the proper interpretation of statistical analyses of its preventing effect. Opponents of capital punishment see the death penalty as a human rights issue involving the proper limits of governmental power. In contrast, those who want governments to continue to execute tend to regard capital punishment as an issue of criminal justice policy. Because of these alternative viewpoints, there is a profound difference of opinion not only about what is the fight answer on capital punishment, but also about what type of question is being asked when the death penalty becomes a public issue.
We can learn from the first paragraph that in ancient times ______.
A．death penalty had been carried out before government came into being
B．people thought it was right for the government to conduct executions
C．death penalty was practiced scarcely in European countries
D．many people considered capital punishment unjust and cruel

Night of the Living Ants
When an ant dies，other ants move the dead insect out of the nest．This behavior. is interesting to scientists，who wonder how ants know for sure-and so soon-that another ant is dead．
Dong-Hwan Choe，a scientist at the University of California，found that Argentine ants have a chemical on the outside of their bodies that signals to other ants，“I’m dead-take me away．”
But there's a twist to Choe's discovery．Choe says that the living ants-not just the dead ones -have this death chemical．In other words，while an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's dead．
What keeps ants from hauling away the living dead？Choe found that Argentine ants have two additional chemicals on their bodies，and these tell nearby ants something like，“Wait-I'm not dead yet．” So Choe's research turned up two sets of chemical signals in ants：one says，“I'm dead，”the other set says，“I'm not dead yet．”
Other scientists have tried to figure out how ants know when another ant is dead．If an ant is knocked unconscious，other ants leave it alone until it wakes up．That means ants know that unmoving ants can still be alive．
Choe suspects that when an Argentine ant dies．the chemical that says“Wait-I'm not dead yet” quickly goes away．Once that chemical is gone，only the one that says“I'm dead”is left．“It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new，unique chemicals after death，”said Choe．When other ants detect the“dead”chemical without the“not dead yet”chemical，they haul away the body．This was Choe's hypothesis(假设)．
To test his hypothesis，Choe and his team put different chemicals on Argentine ant pupae(蛹)． When the scientists used the“I'm dead”chemical，other ants quickly hauled the treated pupae away． When the scientists used the“Wait-I'm not dead yet”chemical，other ants left the treated pupae alone． Choe believes this behavior. shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants．And that when an ant dies，the“not dead yet”chemical fades away． Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest．
The phrase“this death chemical”in paragraph 3 refers to
A．the chemical that contains poison．
B．the chemical that announces death．
C．the chemical that prevents death．
D．the chemical that causes death．
