so what question is this you got given in class?

Please realize that we are not supposed to answer home work questions for you.  Your question sounds like home work, at least to me it does.

Some reasons for slow LAN are know are:

Viruses,worms,trojan horses residing on your workstatins or servers.
Solution and reasons for the above is to install anti-virus softwares which can be found here;

Damage on one of your communication media. Examples being Fibre optic,UTP,coaxial cables on you LAN.
Solution for the above is to hire a Network Company to perform checks on the cabling on you LAN.Reason are damage by electricity and worn out cables.

Bandwidth(Amount of information that can be sent through a communication channel or media)- It  can be measured in KBps or MBps normally. This one is directly related to the distance. A rule of thumb is if you sent data to a distant place increase bandwith,that is the more the distance the more the bandwith is required.
Solution for the above: Increase bandwidth.

To correct you on your points above:
RAM in workstations.(Should be RAM in a Server)
CPU in workstations.(Should be CPU in a Server)
Upgrades in applications (i.e., upgrade in Windows)
Increase in graphics use.
The above does not affect you network performance but instead they affect the individual PC performance.

Increase in traffic and loading.-You are right
Increase in number of nodes.-You are right
The two above affects each other to some extent. If you increase nodes that means you increase the number of users that will access Internet, remote softwares like Integrated Patient Management System etc.

Hope I tried to help with my little knowledge.
