Q13:
Certain genetically modified strains of maize produce a powerful natural insecticide. The insecticide occurs throughout the plant, including its pollen. Maize pollen is dispersed by the wind and frequently blows onto milkweed plants that grow near maize fields.Caterpillars of monarch butterflies feed exclusively on milkweed leaves. When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die. Therefore, by using genetically modified maize, farmers put monarch butterflies at risk.

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
B. Whether the pollen of genetically modified maize contains as much insecticide as other parts of these plants
C. Whether monarch butterfly caterpillars are actively feeding during the part of the growing season when maize is releasing pollen
D. Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plant’s pollen
E. Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields

Answer:C

這一題C不懂為何?
我選了D,因為D直接問出了吃了基因改造玉米的蟲是不是有可能被植物中花粉的殺蟲劑殺了.這樣不是更容易evaluate嗎?

D選項脫離範圍了
轉移到其他的殺蟲劑

[lunar916]

請問D 如何轉移到其他的殺蟲劑?
D. Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plant’s pollen

我覺得CDE都好像有關西
可是C跟E并沒有跟conclusion:Therefore, by using genetically modified maize, farmers put monarch butterflies at risk. 有直接關西
C: caterpillars are actively or inactively feeding,有genetically modified maize都可能對毛蟲造成危險

D選項脫離範圍了
轉移到其他的殺蟲劑

奇怪 怎麼心裡想的跟講出來的會不一樣呀
D選項應該是轉移到其他 insect....

C選項可以判斷monarch butterflies會不會去吃到殺蟲劑

維尼大大,但是D沒有講到"其他的殺蟲劑"呢!

[Janet]

維尼大大,你的意思該不會是說.

D選項脫離範圍了
轉移到其他的''蟲''了

題目是monarch caterpillars

[維尼]

題目是monarch caterpillars

是的~
因為把範圍移轉(這邊是擴大)到 insects
如果這個insecticide只對monarch caterpillars有用
那此evaluation為否
但實際上還是有用

[lunar916]

我又看了一下,文章已經說了: When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die.
所以D并不用evaluate

可是... E勒?
如果有其他人來搶吃的,這些caterpillars就吃不到啦~ @@

如你的推論
e是一個可能選項
但是只要caterpillar會吃到 就是at risk
所以我覺得e選項還不夠清楚表示caterpillar會不會吃到

相對來講 我覺得c選項直接點出會不會吃到
會比較好
