R4.
Describe why an application developer might choose to run an application over UDP rather than TCP
An application developer may choose to run an application over UDP rather than TCP because UDP is known to be faster than TCP and will work well for real time apps. Also
with UDP you can control the sending rate. UDP is also beneficial because its connectionless and can support more clients.

R6.
Is it possible for an application to enjoy reliable data transfer even when the application runs over UDP? If so, how?

I believe this is possible, a developer could put reliable data transfer into the application layer protocol. This could be done but is very labor and time intensive and a lot of debugging must take place.
