23.As government agencies, faced with budget difficul-
ties, reduce their funding for scientific research, a
greater amount of such research is being funded by
private foundations. This shift means that research
projects likely to produce controversial results will
almost certainly comprise a smaller proportion of all
funded research projects, since private foundations,
concerned about their public image, tend to avoid
controversy.
Which of the following is an assumption on which
the argument depends?
(A) Only research that is conducted without concern
for the possibility of generating controversy is
likely to produce scientifically valid results.
(B) Private foundations that fund scientific research
projects usually recognize that controversial
results from those projects cannot always be
avoided.
(C) Scientists who conduct research projects funded
by private foundations are unlikely to allow the
concerns of the funding organizations to influ-
ence the manner in which they conduct the
research.
(D) Many government agencies are more concerned
about their public image than are most private
foundations.
(E) Government agencies are more willing than are
private foundations to fund research projects
that are likely to produce controversial results.
24.Juries in criminal trials do not base verdicts on uncor-
roborated testimony given by any one witness. Rightly
so, because it is usually prudent to be highly skeptical
of unsubstantiated claims made by any one person.
But then, to be consistent, juries should end an all-
too-common practice: convicting defendants on the
basis of an uncorroborated full confession.
Which of the following, if true, most strengthens the
argument above?
(A) Juries often acquit in cases in which a defendant
retracts a full confession made before trial.
(B) The process of jury selection is designed to screen
out people who have a firm opinion about the
defendant's guilt in advance of the trial.
(C) Defendants sometimes make full confessions when
they did in fact do what they are accused of
doing and have come to believe that the prose-
cutor has compelling proof of this.
(D) Highly suggestible people who are accused of
wrongdoing sometimes become so unsure of
their own recollection of the past that they can
come to accept the accusations made againstthem.
(E) Many people believe that juries should not convict defendants who have not made a full confession.
25.Although spinach is rich in calcium, it also contains large amounts of oxalic acid, a substance that greatly impedes calcium absorption by the body. Therefore, other calcium-containing foods must be eaten either instead of or in addition to spinach if a person is to be sure of getting enough calcium.
Which of the following, if true, most seriously weakens the argu-ment above?
(A)Rice, which does not contain calcium, counteracts the effects of oxalic acid on calcium absorption.
(B) Dairy products, which contain even more calcium than spinach does, are often eaten by people who eat spinach on a regularbasis.
(C) Neither the calcium nor the oxalic acid in spinach is destroyed when spinach is cooked.
(D) Many leafy green vegetables other than spinach that are rich in calcium also contain high concentrations of oxalic acid.
(E) Oxalic acid has little effect on the body's ability to absorb nutrients other than calcium.
