Sorry, i don’t see the paragraph
<span>We stretched and then slowly jogged once around the track</span>
.org, .gov, .edu are usually the most reliable domains when it comes to dealing with english related assignments.
.org - means the website is from an organization, without the intention of selling commercial products.
.gov - is from the government so we know that this is reliable
and .edu is usually for university websites.
Hope this helped.
