In conclusion, the argument is unconvincing as it stands. To strengthen the assertion that
lavender-scented pillows provide a short-term cure for insomnia, the author must provide
evidence that the test subjects' insomnia was worse just prior to the experiment than at the
conclusion of the experiment, and that the number of subjects is statistically sufficient to
warrant the conclusion. To better assess the argument, we would need a clear definition of
insomnia, as well as more information about whether the researchers conducted the
experiment in a controlled environment.
Argument 56
Typically, as people age, their bone mass decreases, making them more vulnerable to bone
fractures. A recent study concludes that the most effective way to reduce the risk of fractures in
later life is to take twice the recommended dose of vitamin D and calcium daily. The three-year
study followed a group of French women in their eighties who were nursing-home residents.

The women were given daily supplements of twice the recommended dose of vitamin D and
calcium. In addition, the women participated in a light weightlifting program. After three years,
these women showed a much lower rate of hip fractures than is average for their age.
This argument concludes that elderly people should take twice the recommended dosage of
vitamin D and calcium in order to minimize loss of bone mass, and therefore the risk of bone
fractures. To support this conclusion the argument's proponent cites a 3-year study involving a
group of French female nursing-home residents in their eighties. After three years of weight
training, along with taking the indicated dosages of vitamin D and calcium, these women as a
group were observed to suffer far fewer hip fractures than is average for their age. This
argument suffers from several critical flaws and is therefore unconvincing.
First and foremost, the argument assumes unfairly that the additional vitamin D and calcium,
rather than the weight training, were responsible for the lower-than-average incidence of hip
fractures among this group of women. It is entirely possible that the weight training, not the
supplements, was responsible for preserving bone mass. Also, weight training is known to
improve muscular strength, coordination, and flexibility, which in turn might reduce the
likelihood of accidental falls and other injuries. Thus the weight training could also have been
responsible in this respect.
