Hi guys, sorry about the title..I did the question several days ago..so I forget it comes from which PT..As soon as I find out i will change the discussion title.
Studies of the reliability of eyewitness identifications show little correlation between the accuracy of a witness's account and the confidence the witness has in the account. Certain factors can increase or undermine a witness's confidence without altering the accuracy of the identification. Therefore, police officers are advised to disallow suspect lineups in which witnesses can hear one another identifying suspects.
Which one of the following is a principle underlying the advice given to police officers?
(A) The confidence people have in what they remember having seen is affected by their awareness of what other people claim to have seen.
(B) Unless an eyewitness is confronted with more than one suspect at a time, the accuracy of his or her statements cannot be trusted.
(C) If several eyewitnesses all identify the same suspect in a lineup, it is more likely that the suspect committed the crime than if only one eyewitness identifies the suspect.
(D) Police officers are more interested in the confidene witnesses have when testifying than in the accuracy of that testimony.
(E) The accuracy of an eyewitness account is doubtful if the eyewitness contradicts what other eyewitnesses claim to have seen.
I think here in the conclusion 'Dealership rather than National Rental is more worthwhile for Local than for Tourists', the extent of WORTHWHILE is measure by the difference of money spent on dealership and national rental. For example, if it cost the tourists 50 to use dealership and 70 to use national rental, while it costs locals 30 to use dealership and 80 to use national rental, we say it is more worthwhile for locals than tourists because for the tourists the difference is only 20 but for the locals the difference is 50.
Therefore, for answer choice B, if the tourists spend extra money on taxi rides, that is new information hinting the difference should be somewhat narrowed. Therefore strengthen the conclusion.
It didn't come up to me the assumption that the national rental is near the airport..so I reread the conclusion and figure it out in the way above.
