"the deadliest tsunami in history" is a news article, while "orphans give indian
couple will to live" is a feature article. explain the difference in the way the
information is presented in these two articles.

The difference is based on factual v.s experiential information.

Explanation:

In both cases the goal of the articles is to discuss events, but the approach varies in terms of how the information is delivered, let me elaborate:

The idea behind a News Article, is to deliver a neutral and factual view of a particular event, thus it delivers hard data as it is statistics, polls, interviews. Usually this information is accompanied by dates or extra information that can lead the reader to conclusions or strengthen the argument of the writer. Usually provides the perspective of the article right away, and it expands by means of information in order to endorse the argument.In the case of a Featured Article is a more lighthearted approach, and doesn't need the resource of hard data in order to deliver the story, it rather centers in research, quotes and descriptions and also tend to rely on personal interviews and points of views to express the narratives. The story develops little by little and focuses on emotional buildup, so that at the end of the article it reveals the main point at the end of it.
