III. Identifying parts of an argument. For each of the following arguments, identify the
main conclusion and the reasons. Say whether there are any intermediate conclusions.
Say whether the reasons support the conclusion jointly or independently.
1. The odds that a dangerous leak from a nuclear power plant could occur are so small as to
be almost impossible to calculate. I have as much chance of being seriously injured backing
out of my drive as I would be living next to a nuclear power plant for a year. So someone
living next door to a nuclear power plant should feel 100 per cent safe. independently
2. The one third of people who smoke in public places are subjecting the rest of us to
discomfort. What is more, they are putting our health at risk, because ‘passive’ smoking
causes cancer. That is why it is time to ban smoking in public places. independently
3. Radioactive elements disintegrate and eventually turn into lead. So if matter has always
existed there should be no radioactive elements left. The presence of uranium and other
radioactive elements is scientific proof that matter has not always existed. jointly
4. A foetus’s heart is beating by 25 days after fertilization. Abortions are typically done
seven to ten weeks after fertilization. Even if there were any doubt about the fact that the life
of each individual begins at fertilization, abortion clearly destroys a living human being with
a beating heart and a functioning brain. If the first right of a human being is the right to his or
her life, the direct killing of an unborn child is a manifest violation of that right. jointly
5. It has always been the case in the past that new discoveries of mineral reserves have kept
pace with demand. For example, bauxite reserves have tripled in the last ten years, while
demand has doubled over the same period. At no time have the known reserves of minerals
been as great as the total mineral resources of the world. Therefore, even though at any given
time we know of only a limited supply of any mineral, there is no reason for us to be
concerned about running out of mineral resources. independently
6. In rape cases, sentences should be lighter for those who plead guilty than for those who
plead not guilty. For a victim of rape, appearing in court is a very distressing experience. If
the defendant pleads guilty, the victim does not have to appear in court. If sentences are as
heavy for those who plead guilty as for those who plead not guilty, all defendants will plead
not guilty, because there is nothing to lose. jointly
7. If imprisonment worked as a deterrent to potential criminals, the more people we had in
prison to serve as examples, the more would their lesson be conveyed to those outside
prison. But today we have record numbers of people in prison, and a crime rate which is
growing, not decreasing. Thus, imprisonment is not an effective deterrent. jointly
8. Those who oppose any and all restrictions on freedom of the press are wrong. Consider
the effects of freedom to report on cases of kidnap. Experience shows that kidnap victims are
less likely to be killed by their captors if the kidnapping is not reported. To report a kidnap
can thus endanger a victim’s life. If we do not pass legislation against publishing in these
circumstances, some newspapers will continue to be irresponsible and will publish details of
the kidnapping before the victim is released or rescued. jointly
