A topic sentence presents the main gist of the whole paragraph or article. So, if you want to talk about building a snowman, your topic sentence could be about why building snowmans are of relevance. Then, your supporting details could now include steps or advices on how to build it.

<em>During the yuletide season, building a snowman is a good activity to do with family and friends because it promotes team-building and fun interaction.</em>

Benjamin Franklin published it
Hands Across America was a public event on Sunday, May 25, 1986, in which approximately 6.5 million people held hands for fifteen minutes in an attempt to form a continuous human chain across the contiguous United States.
Many participants donated ten dollars to reserve their place in line. The proceeds were donated to local charities to fight hunger and homelessness and help those in poverty.
The event raised about $15 million for charities after operating costs.
Hope it helped :)
