report insist the conclusion be changed to, “Most forests in Canada do not show visible symptoms of damage by
acid rain, such as abnormal loss of leaves, slower rates of growth, or higher mortality.”
Which of the following, if true, provides the best logical justification for the critics’ insistence that the report’s
conclusion be changed?
(A) Some forests in Canada are being damaged by acid rain.
(B) Acid rain could be causing damage for which symptoms have not yet become visible.
(C) The report does not compare acid rain damage to Canadian forests with acid rain damage to
forests in other countries.
(D) All forests in Canada have received acid rain during the past fifteen years.
(E) The severity of damage by acid rain differs from forest to forest.
Ans: B
Because the authors of the report evidently resist the change being demanded, any claim on which they and
their critics are likely to be in agreement cannot provide justification for the change. Choices A, C, D, and E are
all claims both parties can agree on, so none of them is correct.
