Set 2.	Understanding of harm reduction policies associated with HIV and assessing efficacies according to different participation rates and activation dates.	6.71	1.03	8.29	0.45	−5.08	P<0.001
(b) Flu simulation
Set 1.	Understand of epidemiology concepts associated with influenza and transmission dynamics of the 1918 influenza pandemic.	5.63	1.15	7.77	1.26	−5.89	P<0.001
Set 2.	Assessing and analysing the prevention effects of five public health policies at low and high regional densities and with three policy activation dates (10/1∼10/07, 10/22∼10/28, and 11/19∼11/25).	5.13	0.62	6.68	0.9	−6.86	P<0.001
Set 3.	Assessing and analyzing the cost-efficacies of five public health policies at low and high regional densities with three policy activation dates (10/1∼10/07, 10/22∼10/28, and 11/19∼11/25).	5.68	0.47	6.40	0.49	−5.41	P<0.001
