Answer 1

Answer:

D. Crowdsourcing

Explanation:

Crowdsourcing can be defined as a collaborative process which typically involves completing a project (task) and solving a problem through a group of people (crowd) that are geographically dispersed over the internet.

Basically, crowdsourcing refers to an outsourcing technique which allows a project or task to be jointly completed by a group of people (crowd) such as volunteers or freelancers who are made to work remotely over the internet.

In this scenario, an online music provider such as Pandora or Jango uses crowdsourcing for collaborative filtering, which helps define the list of songs available to listeners.
