QUESTION TEXT: A commercial insect trap consists of a…
QUESTION TYPE: Weaken
CONCLUSION: Scientists think that insects have become resistant to the pesticide.
REASONING: The pesticide traps lure insects with glucose. They don’t work as well as they used to.
ANALYSIS: There are only two factors mentioned: glucose and pesticide. To weaken the idea that pesticides are less effective, we can instead say that glucose is less effective.
___________
- CORRECT. This shows that the traps have cut down the number of bugs that like glucose. Pesticide might still kill the bugs, but they’re no longer very attracted to the traps.
- This strengthens the idea that the insects resist the pesticide. The bugs that survived were likely to breed pesticide resistant insects.
- This is consistent with the theory. The theory would predict that insects in houses that haven’t used the trap haven’t become pesticide resistant.
- This supports the idea that the insects are becoming immune to the pesticide. If it doesn’t hurt insects, then more pesticide won’t help.
- Who cares what kind of glucose is used? As long as the same type has been used the whole time, it shouldn’t matter whether the glucose is natural.
