A historian writes an essay on the effects of the Great Depression. He claims that the Depression mostly harmed
rural Americans and that people living in the cities
generally had no idea it was even happening.
A reader trying to determine whether the historian's interpretation is valid
would most likely:
O A. conduct research on the Great Depression to learn about the
factors that caused it.
B. determine whether the historian has written any other essays on
the Great Depression.
O C. write an argumentative essay suggesting that the historian does
not care about the poor.
O D. search for Depression-era primary sources from cities to see if
they mention urban poverty.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
