Task2
Reading:
First-Year Room Change Requests
Currently, first-year students are expected to live in their assigned dormitory rooms until the end of the semester; if they wish to change rooms, they need to wait until the semester is over to request a new room. However, I think first-year students should be able to request a room change at any time. Some students have roommates who are simply not a good match, which can make it difficult to focus on their studies. To discourage students from making the decision too hastily, the university could charge a small amount of money; this would help limit requests to only those students who most needed it.
Sincerely,
Paulo Haddon

Task3
Reading:
Paleoendemic Species
Certain animal and plant species are native to one specific area and are found nowhere else in the world. If such species once lived over larger geographical areas in the past, they are known as paleoendemic species. Originally, the paleoendemic species was part of a large plant or animal population that was spread out over a wide area, but at some point it became separated from the larger population. Environmental conditions then caused the larger part of the species population to die out and become extinct. However, the smaller, separate paleoendemic population was able to survive in its isolated location.
Explain how the example of the reptile illustrates the concept of paleoendemic species.
Task4
