Backyard gardeners who want to increase the yields of their potato plants should try growing stinging nettles alongside the plants, since stinging nettles attract insects that kill a wide array of insect pests that damage potato plants. It is true that stinging nettles also attract aphids, and that many species of aphids are harmful to potato plants, but that fact in no way contradicts this recommendation, because _______.

Which one of the following most logically completes the argument?

(A) stinging nettles require little care and thus are easy to cultivate
(B) some types of aphids are attracted to stinging nettle plants but do not damage them
(C) the types of aphids that stinging nettles attract do not damage potato plants
(D) insect pests typically cause less damage to potato plants than other harmful organisms do
(E) most aphid species that are harmful to potato plants cause greater harm to other edible food plants

It is true that stinging nettles also attract aphids, and that many species of aphids are harmful to potato plants, but that fact in no way contradicts this recommendation, because _______.

Which one of the following most logically completes the argument?

SO I NEED TO SRENGTHEN RECCOMEDATION DESPITE THE FACT THAT STINGING NETTELES ATTRACT MANY SPECIES OF APPHIDES THAT ARE HARFUL TO POTATOS.

(A) stinging nettles require little care and thus are easy to cultivate (NOT CONCERNED WITH CULTIVATION)

(B) some types of aphids are attracted to stinging nettle plants but do not damage them (SO WHHAT SOME ARE NOT, BUT MOST ARE HARMFUL :lol: )

(C) the types of aphids that stinging nettles attract do not damage potato plants ( CORRECT, THE ONLY LOGICAL ANSWER CHOICES, SINCE THERE ARE MANY APHIDES SPIECIES, THE ONES THAT ARE ATRRACTED ARE NOT HARMFUL FOR POTATO PLANTS)


(D) insect pests typically cause less damage to potato plants than other harmful organisms do ( THIS DOESNT SAY ANYTHING IN FAVOR OF RECCOMEDATION)

(E) most aphid species that are harmful to potato plants cause greater harm to other edible food plants ( NOT CONCERNED WITH OTHER FOOD PLANTS, APHID SPECIES WILL STILL DAMAGE POTATO PLANTS, I THINK THESE APHIDES SPECIES LOVE CHIPS VERY MUCH :lol: )

Can someone explain option B please? Option B clearly states that the type of aphids which are attracted to potato plants do not damage them. I agree that the stimulus mentions 'many species of aphids are harmful to potato plants' but does not state that they are all attracted by potato plants. Option C and Option B are very close and thus difficult to choose.
