The Colorado beetle originally fed on a particular type of plant. Howe

The larvae come from beetle reproduction. They are the 'baby beetles.'

We don't really need to understand *why* rapid reproduction helps the beetles develop a quick resistance to toxins. C could be "Because [any reason at all], it quickly develops a resistance to toxins." The fact that there's *anything* that causes the beetle to quickly become resistance to toxins makes the use of pesticide (a toxin) a less than ideal strategy, as the beetle could very well become resistant to it quickly.



Think of this situation:

"John bakes delicious cookies. When he brings them to the office, everyone is happy. He usually brings them the first Tuesday of every month, which next Tuesday. But if he brings freshly baked cookies next Tuesday, they probably will not make the office happy, because __________"

C). Since John's break-up with his partner, he has been unfocused and his baking has suffered.


So the argument is about the cookies (the larva) that usually make the office happy (that devastate the potato crops), but the cookies come from John (the larvae are born from the beetles.) There's a plan to bring cookies (to use pesticide to control the beetle population). We're trying to say why the plan will fail at its objective.

If John is not baking as well as he usually does (and who really cares why...) it's less likely his cookies will be as good, and therefore might fail to make the office happy.

If the beetles develop resistance to toxins (and who really cares why...) it's less likely the pesticide will be able to control the beetle population.
