Only POE works!!

A certain variety of spear thistle, a weed that quickly spreads across grasslands, was inadvertently introduced into Canada from the United Kingdom in the late 1960's. This weed takes nutrients and moisture from the soil that would otherwise go to timothy grass, the most common Canadian grass varietal. To help track the spread of spear thistle, the Canadian government has released a fact sheet to farmers to help them identify the weed-the fact sheets contain pictures of the weed and explain its effect on soil; the sheets also ask farmers to report any outgrowths of the weed found on their land.

Which of the following, if true, would provide the most support for the prediction that the agencies' action will have its intended effect?

(A) The spear thistle is one of several foreign weed species that draws nutrients from the soil of Canadian farmers.
(B) The animals that graze on timothy grass on Canadian farms are uninterested in eating spear thistle because of its thorns.
(C) The spear thistle leaves spiny thorns on the ground which can poke holes in timothy grass.
(D) Spear thistles usually draw nutrients out of the soil at night, but timothy grass usually grows during the daytime hours.
(E) Most Canadian farmers use timothy grass as the main varietal with which to feed and nourish their livestock.

Choice B helps the government achieve the intended effect. The animals help the farmers in identifying the weed

"pictures of the weed and explain its effect on soil"

Thus, the farmers will be able to recognize a weed with which they are familiar.

So E is the winner!!
