### HideShow timer Statistics

A certain experimental fungicide causes no harm to garden plants, though only if it is diluted at least to ten parts water to one part fungicide. Moreover, this fungicide is known to be so effective against powdery mildew that it has the capacity to eliminate it completely from rose plants. Thus this fungicide, as long as it is sufficiently diluted, provides a means of eliminating powdery mildew from rose plants that involves no risk of harming the plants.
Which one of the following is an assumption on which the argument depends?
(A) There is not an alternative method, besides application of this fungicide, for eliminating powdery mildew from rose plants without harming the plants.
(B) When the fungicide is sufficiently diluted, it does not present any risk of harm to people, animals, or beneficial insects.
(C) Powdery mildew is the only fungal infection that affects rose plants.
(D) If a fungicide is to be effective against powdery mildew on rose plants, it must eliminate the powdery mildew completely.
(E) The effectiveness of the fungicide does not depend on its being more concentrated than one part in ten parts of water.

Conclusion of the argument:
Thus this fungicide, as long as it is sufficiently diluted, provides a means of eliminating powdery mildew from rose plants that involves no risk of harming the plants

B - Harm to people, animals, or beneficial insects has nothing to do with the conclusion. If you tried to link beneficial insects to harming planits you were thinking to hard and made an unjustified assumption.

I arrived at E by POE.

Negate E

The effectiveness of the fungicide depends on its being more concentrated than one part in ten parts of water

Conc is

Thus this fungicide, as long as it is sufficiently diluted, provides a means of eliminating powdery mildew from rose plants that involves no risk of harming the plants

So Negated E is saying effectiveness depends on more concentration of the F. if it is correct as long as sufficiently diluted does not hold good and the F might not provide the means. So Conc falls apart.

Hence E

Hi mates,

icandy, To be honest I don't see why E is correct I mean, if this fungicide is diluted in a wrong proportion, it can damage the plant (first part of the question)

E says that the effectiveness of that fungicide does not depend on the proportion water VS fungicide, but in fact, as the question says, it does...

For me, it would be D

what do you think guys?

BTW, what's the source?

Cheers
