Critical Reasoning (CR) | Re: For every 40 cats that contract a particular ear infection

Although I fell for D, I later realized that E makes sense.

If the no. of cats that contract the infection is significantly less than the total, chances are that more cats might be killed due to vaccination.
If the no. of cars that contract the infection is significantly closer to total, then vaccination is a good idea.

I too second the thought that option is poorly phrased. It should have included the total as well.
