Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations
Problem:
In the fall, they eat a significant portion of the province’s sunflower crop.
Plan:
This year Midland farmers sought permits to set out small amounts of poisoned rice during the blackbirds’ spring stop in order to reduce the fall blackbird population.
Problem with the Plan:
Some residents voiced concern that the rice could threaten certain species of rare migratory birds.
Final Verdict:
Wildlife agency approved the permits.
The blackbirds stop in the region every spring and every fall. In the fall they ruin sunflower crop. So, the farmers want to reduce the population of the birds in spring so that when they come back in fall, they don’t ruin the crop much. Some residents worry that the poison could threaten some rare migratory bird species.
We need to justify the approval of the permits given the concerns voiced by some residents. This means we need to strengthen why the plan is acceptable i.e. why the concern raised by some residents may not be valid i.e. why the rare migratory birds may not be in danger from the poisonous rice.
A. In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
If blackbirds are the first birds to appear, they could be fed the poison at that time and other migratory bird species would not be in danger. This alleviates the concern of the residents and helps the plan.
Correct.
B. The poison that farmers want to use does not kill birds but rather makes them incapable of producing viable eggs.
This will harm the rare migratory birds since they will not be able to reproduce. It doesn’t strengthen the validity of the approval given.
C. Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice.
The residents’ concern is regarding some rare migratory species, not native species. So, this option is irrelevant.
D. Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined.
The point is whether the permit is justified. The punishment for going ahead with the plan without permit is irrelevant.
E. The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.
This says that the birds will not be able to detect the poison and hence, will eat the rice. So, the poison will impact all the birds that will eat the rice set out and hence, will impact rare migratory birds too. This doesn’t help our plan.

Eliminating E was hard for me.
There is mention of Migratory birds and Black Birds and how Black birds stop (take a break) in this region during spring and come back for fall and eat all the sunflower is a problem for farmers, so Farmers have gotten their approval to add poisoned rice in very less quantities to control Black bird population.
Fear: Migratory and rare species could die too.
What reason could tell you that this approval is justified.
A - good choice.
If Black birds are the first to reach that region and if the poisonous rice is indeed low in quantity it is entirely possible that Black birds consume them and therefore reduction in population happens and doesn't impact much on migratory birds
E- The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.
I was confused as they were "migratory" birds there could be a possibility that they are not taking a stop in this region therefore if you make it undetectable by birds
this could mean that there is a good chance that migratory birds don't see them, and only these birds that take a stop see them.
But I was also worried that I can't assume migratory birds won't take a stop so, if they did stop then that would mean killing the birds if they arrived earlier
so I had to choose A, A was slightly better.
