Which of the following statements best describes the response of finches to drought on the Galapagos Islands?
During drought, individual finches saw that large, hard seeds were the only available food. To crack these harder seeds, individual finches grew their beaks larger, resulting in an increased average beak depth.
During drought, finches struggled to open harder seeds. All the scraping and pecking wore down their beaks, resulting in a reduced average beak depth.
During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-beaked finches died, resulting in an increased average beak depth in the population.
B?

I haven't read your article, but I disagree with your answer.
EH, thanks anyways ill go with c.. and therewasnt an article... directions said answere these question about finches and a hard seed
Right.
thx
u gave me the wrong answer u are cursed for life u
Correct Answer is C). During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-beaked finches died, resulting in an increased average beak depth in the population.
Explanation:
Normally, reducing food supplies would favor animals with smaller bodies because they don't need as much food to survive. On the Galapagos Islands, however, only large seeds are available during the drought. Small-beaked finches are not able to access this food supply, so they are more likely to starve. Many of the large-beaked finches are likely to die as well, but some will be able to live on a hard-seed diet. As these finches survive and produce offspring, the average beak depth increases.
