If you are looking for a definition in a story, it is best to look at the key words around the word you might not know, for example; 'prowess.' They mention before the word, 'his own strength.' And after the word, 'surviving triumphantly.' Triumphantly means achievement, or great joy. Meaning the word has to be a positive sided word, which is 'expertise; skills.' If you also are unsure after looking at the surroundings, you can look up the definition. Google says; 'expert skill or knowledge in a particular field. ' for the meaning 'expertise; skills.' This technique helps break down the other choices and meanings to the correct answer. Hope this helps!
