Children whose biological parents both have Tic Syndrome Z(TSZ), which is characterized by the involuntary contraction of certain muscles, are about four times more likely to develop such contractions than are children whose biological parents do not have TSZ. 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.

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.
