Answer:
A real war and a "war" of fighting to grow old and successful
Explanation:
Based on the excerpt, Robert Louis Stevenson was reminiscing about his days as a younger man and the internal conflicts he had.
In the first paragraph, he talked about the real war he witnessed where he heard the "loudness" of the battles and the "pain of men's wounds". He also talked about another internal "war" which had to do with "slavery of competition", toiling for years and which culminated to fighting to be old and successful.
Extra words in a sentence that add detail and are set off by commas are called nonessential elements. This is because they are not essential to the sentence and story, they are simply an added bonus, without them the sentence still makes sense.
When utilizing words within a sentence, we must first recognize two things: their definition and the ways that they can be used. As such, when we have these elements, we can generate sentences that not only use them correctly, but through these sentences we can further understand the meaning of the words through context. Defy, as per the dictionary, means to disobey an order, or challenge someone or something and unequal means not being able, or not having the resources, to deal with someone or a situation, or also, a variation in size, shape or other characteristics that make two things differ and one be superior to the other.
As such, a good sentence to combine these two words could be thus: We have always been unequal to the task of dealing with corrupt people because we fear to defy those who we perceive have power and control over us.
