PPP- straightforward

Poverty; designing a poster is interesting, I like Starbucks coupons

2. Refugee

Chose poverty because it was simple and straightforward. Did refugee because all the other ones were taken and the reward was pretty good

2. PPP healthcare

Choosing poverty because the platform only requires us to finish an easy + non-time-consuming questionnaire, simple proposal and peer voting.

Choosing PPP because it didn't require me a lot of time. Though there's no incentive, I think the experience is fruitful as I was required to read related information before completing the moodle entry.

User-friendly design;

Informative background

Not only is the instructions clear, but more importantly the platform allows us to see the outcome. It's critical to me that I can see what I have contributed.

Easy and reward
