Argument Analysis :

Certain genetically modified strains of maize produce a powerful natural insecticide. A background information.
The insecticide occurs throughout the plant, including its pollen. A background information.
Maize pollen is dispersed by the wind and frequently blows onto milkweed plants that grow near maize fields. A background information. Milkweed plants – new actor in the argument
Caterpillars of monarch butterflies feed exclusively on milkweed leaves. A background information. Caterpillarsone more actor related to Milkweed plants.
When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die. A background information – impact of modified strains of maize
Therefore, by using genetically modified maize, farmers put monarch butterflies at risk. Conclusion.

Assumptions -
a. Maize pollen is dispersed by the wind and frequently blows onto milkweed plants.
Assumes that pollens stay as well and wind is not strong enough to disperse pollens in short span of time or may be rain followed by wind to remove the pollens.
b. Caterpillars of monarch butterflies feed exclusively on milkweed leaves:
To remove / reduce the impact of pollens, Milkweed does not produce any natural defense such as chemical etc., which may affect caterpillars.
c. Caterpillars of monarch butterflies feed exclusively on milkweed leaves : maize and milkweed are grown in the same season hence pollens impact the caterpillar feeds.
d. Amount of pollens are significantly enough to impact the caterpillars.

Question stem :
Which of the following would it be most useful to determine in order to evaluate the argument?

A. Whether the natural insecticide is as effective against maize-eating insects as commercial insecticides typically used on maize are – Argument is about impact on caterpillar
B. Whether the pollen of genetically modified maize contains as much insecticide as other parts of these plants – So what only pollens are dispersed
C. Whether monarch butterfly caterpillars are actively feeding during the part of the growing season when maize is releasing pollen –
Yes : then argument is strengthened
No : then argument is weakened


D. Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plants pollen – So what .Impact on other insects is not good enough to conclude about caterpillars
E. Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields – Let them compete …where is impact of pollen?

Option C
