Given below is a passage followed by a statement about that passage. You must select one of the following answers:
Mediators recognize that the law is generally in place to uphold mediator - client confidentiality, however, there are situations that may occur where the mediator is under obligation to break that confidence. This obligation can vary depending upon where the mediator is practicing and it may occur as a result of their employment contract or of the law. Where such an issue does occur, the mediator is expected to firstly try and discuss the presenting issue with their client; however, in situations where the factors under consideration are particularly urgent, it is accepted that this cannot always be the case.
Legitimate breaches of confidentiality relate to circumstances where the information the client has shared relates to anti-national activities; information of this nature must be reported. There are other circumstances where breaching confidentiality may be considered legitimate, for example, in the case of serious crime or suspected child abuse. Mediation service providers and mediators practicing independently have their own boundaries but must agree with this contractually with their client at the outset of the client - counsel relationship.
Being obliged to break confidentiality in a mediator - client relationship is always a direct result of the law.

Read the following short passage and choose the best answer to the question below that passage.
Modern science is built on the process of posing hypotheses and testing them against observations -in essence, attempting to show that the hypotheses are incorrect. Nothing brings more recognition than overthrowing conventional wisdom. It is accordingly not surprising that some scientists are skeptical of the widely accepted predictions of global warming. What is instead remarkable is that with hundreds of researchers striving to make breakthroughs in climatology, very few find evidence that global warming is unlikely.
The information above provides the most support for which one of the following statements? 

Read the following short passage and choose the best answer to the question below that passage.
Television programs and movies that depict violence among teenagers are extremely popular. Given how influential these media are, we have good reason to believe that these depictions cause young people to engage in violent behaviour. Hence, depictions of violence among teenagers should be prohibited from movies and television programs.
Amrita: But you are recommending nothing short of censorship! Besides which, your claim that television and movie depictions of violence causes violence is mistaken: violence among young people predates movies and television by centuries.
Amrita's attempted refutation of Anita's argument is vulnerable to criticism on which one of the following grounds?

Experts musicologists believe that Beethoven wrote his last piano sonata in 1824, three years before his death. However, the manuscript of a piano sonata was recently discovered that bears Beethoven's name and dates from 1825. Clearly, the experts are mistaken because not every piece that Beethoven wrote was cataloged in his lifetime, and it is known that Beethoven continued to compose until just weeks before his death.

The reasoning in the argument is most vulnerable to which of the following criticisms?

Information that is published is part of the public record. But the information that a reporter collects, and sources that he contacts, must be protected in order for our free press to function free of fear.

The above argument is most severely weakened by which one of the following statements?

A growing number of ecologists have begun to recommend lifting the ban on the hunting of leopards, which are not an endangered species, and on the international trade of leopard's skin. Why, then, do I continue to support the protection of leopards?
For the same reason, I oppose the hunting of people. Admittedly, there are far too many human beings on this planet to qualify us for inclusion on the list of endangered species. Still, I doubt the same ecologists endorsing the resumption of leopard hunting would use that fact to recommend the hunting of human beings.

Which one of the following, if true, would most weaken the author's argument?
