Using this chart of word roots and affixes, which is the most likely meaning of the word triathlon?
A. A very difficult sport
B. A person who competes in two sports
C. A competition that has three parts
D. An athlete who swims, bikes, and runs
Tri means three so look for the one that mentions three. That would make it between C and D. And then athalon means something to do with a contest so it would be C. Hope this helps you out!
