单选题 Some people assert that prosecutors should be allowed to introduce illegally obtained evidence in criminal trials if the judge and jury can be persuaded that the arresting officer was not aware of violating or did not intend to violate the law while seizing the evidence. This proposed “good-faith exception” would weaken everyone’s constitutional protection, lead to less careful police practices, and promote lying by law enforcement officers in court. The argument above for maintaining the prohibition against illegally obtained evidence assumes that
defendants in criminal cases should enjoy greater protection from the law than other citizens do.
law enforcement authorities need to be encouraged to pursue criminals assiduously.
the legal system will usually find ways to ensure that real crimes do not go unprosecuted.
the prohibition now deters some unlawful searches and seizures.
courts should consider the motives of law enforcement officers in deciding whether evidence brought forward by the officers is admissible in a trial.

单选题 A pharmaceutical company tested a new painkiller on 1,000 lab rats that were fed large doses of the painkiller for a two-month period. By the end of the experiment, 39 of the rats had died. The company concluded that the painkiller was sufficiently safe to test on humans. Which of the following, if true, provides the most support for the pharmaceutical company’s conclusion?
The amount of painkiller fed to the rats was substantially greater, in relation to body mass, than the dosage any human would take under normal circumstances.
Because of the different body chemistry of humans and rats, some compounds can be dangerous for rats but safe for humans, and vice versa.
Tests of this same painkiller on dogs showed that 3 out of 50 dogs developed lesions on their livers during the course of the experiment.
The researchers found that during the experiment, the rats showed a significantly lower sensitivity to pain than rats do under normal circumstances.
In an experiment of this length with this number of rats, it is not unusual for up to 50 rats to die during the experiment for reasons unrelated to the experiment itself.
