Dr. Mano, a Lecturer and Researcher at one of the universities in Lusaka city is concerned about the poor academic performance of most of the students at his university. He suspects that their
poor performance is due to excessive alcohol intake at a new social club which was opened a year
ago in the locality of the university. He therefore wants to present his findings to the local City
Council and have the club closed down. What scientific steps can Dr. Mano take to best study his
assumptions?

answer; the correct answer is (beta)

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.
