When we're unsure about what a word means, we can use different methods to figure out its meaning. One way is to look at the context - words and phrases that surround it. The paragraph tells about a racing horse that is trying to catch up with other horses. Based on the context, we can conclude that the word <em>cavorting </em>means <em>leaping and jumping</em><em>. </em>Words that especially lead to this conclusion are <em>scattering her legs around limber, sometimes in the air, and sometimes out to one side.</em>
Another way to find out what a word means is to look it up in a dictionary - an alphabetically arranged listing of words that contains different information about them, including their definitions and how they're used. There, we can see that this is what <em>cavorting </em>means.
His father nods but clenches his fist which means he's not happy with the trial but he's trying. His mother also forces a smile. I think it's D because, though his parents may not like it, they are trying.
