Final answer:
The correct word that means "quarrelsome" and contains the first 7 letters forming a word that means "satisfied" is "contentious", not "argumentative". "Content" is the word within "contentious" that means satisfied.
Step-by-step explanation:
The question asks for a word meaning "quarrelsome", where the first 7 letters form a word that means "satisfied". Looking at the options provided, the correct answer is (d) argumentative. The first 7 letters of "argumentative" are "argument", which on its own does not necessarily mean satisfied, but if we break it down further to just "content", it indeed means satisfied. Therefore, the word "contentious" is the word that fits the description given in the question, meaning quarrelsome, and not "argumentative" as initially considered. This is a good example of how critical thinking should be applied to ensure that we arrive at the correct answer. "Contentious" describes someone who is likely to cause or engage in an argument, which aligns with the extract where the individual's combativeness is heightened due to the heat of a previous discussion and the influence of cocktails.
