PrepTest 53, Section 3, Question 4
A recent test of an electric insect control device discovered that, of the more than 300 insects killed during one 24-hour period, only 12 were mosquitoes. Thus this type of device may kill many insects, but will not significantly aid in controlling the potentially dangerous mosquito population.

Which one of the following, if true, most seriously weakens the argument?
A careful search discovered no live mosquitoes in the vicinity of the device after the test.
A very large proportion of the insects that were attracted to the device were not mosquitoes.
The device is more likely to kill beneficial insects than it is to kill harmful insects.
Many of the insects that were killed by the device are mosquito-eating insects.
The device does not succeed in killing all of the insects that it attracts.
