$($c$)$ Consider the two machine learning problems given below.

$($i$)$ Imagine you are limited in time and need to organize information held in documents

quickly. To be able to complete this ask you need to: understand the theme of the text and

compare it with other documents.

$($ii$)$ Fake news is being created and spread at a rapid rate due to technology innovations such as

social media. The issue gained attention recently during the $2016$ US presidential campaign.

During this campaign, the term Fake News was referenced an unprecedented number of

times. Authorities want to use algorithms to flag some news as Fake correctly or not.

Explain how the clustering technique can be applied to the above problems.
