In response to an alarming increase in the frequency of thefts by pickpockets at Karlarinda’s main airport over the preceding year, Karlarinda’s airport commission posted several large brightly-colored notices in the airport’s most prominent public areas, informing travelers of the recent spate of thefts and warning them to beware of pickpockets.
In the months after these notices were posted, the frequency of pickpocketing thefts at Karlarinda’s main airport grew at an even faster rate than before the notices were posted.
Which of the following, if true, best explains the observed statistical effect of the notices posted by Karlarinda’s airport commission?
(A) Approximately 40 percent of passengers who fly into or out of Karlarinda’s main airport are unable to read any of the languages in which the notices are written.
Even if 40% of passengers are unable to read notices then also this is not the reason why pickpocketing should increase at the airport.
Incorrect
(B) In the seven years since it abolished all sales taxes on purchases made by non-residents, Karlarinda has become one of the world’s premier luxury shopping destinations.
While this may explain why passengers may carry expensive and valuable items at the airport but this has no relation with introduction of notices and fails to explain why pickpocketing cases should increases after putting notices.
Incorrect
(C) The local police department began regular patrols of the public areas of Karlarinda’s main airport on the day when the warning notices were posted.
If local police department began regular patrols of the public areas of the airport, this should have ideally decreased the number of pickpocketing cases at the airport by alarming and preventing thieves from committing any crime.
Incorrect
(D) The tendency of people to physically look or grope for the presence of valuable belongings when they perceive a threat of robbery is widespread across all cultures and demographic groups.
If this is true, and the passengers frequently look and check for valuable belongings after reading notices for staying alert, this may signal pickpockets of the location of valuables and may increase pickpocketing cases instead of reducing them. This explains the paradox in the argument.
Correct
(E) Upon seeing the notices, many travelers purchased belt packs from the airport’s kiosks that are large enough to hold most valuables and that are worn under the traveler’s clothing.
If this is true, many travellers purchased belt packs large enough to hold valuables and that are worn under the traveller's clothing, this should have made pickpocketing more difficult and reduced the number of pickpocketing cases instead of increasing them.
