7-2 What type of reasoning is used in the following argument?
There is every reason to believe that the concussion crisis in NFL football will get worse.
The speed and size of professional athletes have made American football more
dangerous. Offensive linemen now average nearly 315 pounds—65 more pounds than
they did 30 years ago. They launch that weight from a three-point stance, headfirst, at
opposing linemen of nearly the same size. The impact of two such massive players
produces a concussion in the cranium when the brain bangs against the skull. Professor of
Neurology at Boston University, Dr. Ann McKee, notes, “when helmets clash, the head
decelerates instantly, yet the brain continues to lurch forward, like a driver who jams the
brakes on. Even though the skull is protected by a helmet, the brain itself is still in motion
and a concussion is often the result.”
(a) Argument from dilemma.
(b) Argument from authority.
(c) Argument from cause.
(d) Argument from generalization.
7-3 In testing the validity of the argument in question 2, you would be well advised to
ask (a) is the asserted relationship between the grounds and the effect consistent, or are
there instances in which the effect has not followed from these grounds?
(b) are sufficient case or instances cited as grounds to ensure the reliability of the
generalization?
(c) how similar are the cases cited and are the similarities cited key factors?
(d) is this truly an either-or situation?
7-4 Which of the following is NOT a test of argument from cause?
(a) Is the cause capable of producing the effect?
(b) Is the effect produced by the cause or did it occur coincidentally with the cause?
(c) Can the symptom in question be taken as reliable?
(d) Has such an effect always followed such a cause?
7-5 Reasoning from __________ relies on observable symptoms, conditions, or marks
that tell us what is the case.
(a) parallel case
(b) analogy
(c) generalization
