It is likely, therefore, that predisposition to TSZ is an inherited trait. Which of the following, if true, would most strengthen the conclusion above?

A.Children whose parents have TSZ are more likely to develop TSZ if they are under unusual stress at school or at home than if they are not under such stress.

B.Children whose biological parents do not have TSZ are more likely to develop TSZ if they are raised by adoptive parents with TSZ than if they are raised by their biological parents.

C.Children whose biological parents have TSZ are as likely to develop TSZ if they are raised by adoptive parents who do not have TSZ as if they are raised by their biological parents.

D.Children whose biological parents have TSZ and who develop TSZ usually avoid developing a severe form. of the syndrome if they seek treatment for TSZ shortly after developing the first signs of it.

E.Children with TSZ whose biological parents do not have TSZ are less likely to have the syndrome diagnosed when symptoms first appear than are children with TSZ whose biological parents have TSZ.

Juries in criminal trials do not base verdicts on uncorroborated 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 prosecutor 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 against them.

E.Many people believe that juries should not convict defendants who have not made a full confession.

In Bassaria a group of that countrys most senior judges has criticized the uniform. mandatory sentences recently introduced for certain specific crimes.

Which of the following, if true, provides the strongest evidence for the claim that in Bassaria the newly introduced mandatory sentences are not necessarily a change for the worse with respect to achieving true justice as defined in the argument?

A.Before mandatory sentencing, judges in eastern Bassaria imposed strikingly different sentences from those in western Bassaria for equally grave instances of the same kind of offense.

B.In Bassaria the frequency of crimes that have been made subject to mandatory sentences is lower now than it was just prior to the introduction of mandatory sentencing.

C.The law introducing mandatory sentences was passed in the legislature of Bassaria by a large majority and is unlikely to be repealed in the foreseeable future.

D.There used to be a wide difference between the minimum and the maximum sentences allowed by law in cases of crimes now subject to mandatory sentences.

E.In Bassaria judges are appointed for life and are thus not easily influenced by political pressure groups.
