There are only three articles in the English language. One is definite, and two are indefinite. "The" is a definite article, while "a" and "an" are indefinite articles. To answer your question, you need to find the sentence that correctly uses "a" and "an". "A" is used if the word following it begins with a consonant, while "an" is used if the word following it begins with a vowel. Looking at the options provided in your particular problem, you can see that answer choice a is the only one that follows all of the above rules, making it the correct answer.
In his Nicomachean Ethics, Aristotle (384-322 B.C.E.) describes the happy life intended for man by nature as one lived in accordance with virtue, and, in his Politics, he describes the role that politics and the political community must play in bringing about the virtuous life in the citizenry.
The Politics also provides analysis of the kinds of political community that existed in his time and shows where and how these cities fall short of the ideal community of virtuous citizens.
Although in some ways we have clearly moved beyond his thought (for example, his belief in the inferiority of women and his approval of slavery in at least some circumstances), there remains much in Aristotle’s philosophy that is valuable today.
