Read the following article and select the best answer. Article: Art is visible. However, everything one sees is filtered through certain conditions, some of them historical, and others, natural. The historical conditions include the material which is used --oil, color1s, and the canvas; second, a certain style. There can be a general style, for example, the style of Impressionism, or a particular style, for example, the individual ways in which two painters, both impressionists, paint. The natural conditions include certain unchanging psychological laws of sight, for instance, the effects of color1s or optical illusions. The conditions of art are nothing but a particular way of interpreting reality. To understand this, one can examine the difference between the classical Greek and the classical Egyptian styles. For the Greeks, the reality of the visible was given by the perspective and the situation in which the object appears; for that reason they presented a person in his individual movements. For the Egyptians, however, this was only the appearance of a brief moment, which, according to their beliefs, was not real. Therefore, the Egyptians searched for the permanent essence and the typical character in their depiction of an object. For the Egyptians, Greek art was an illusion; for the Greeks, on the other hand, Egyptian art was unrealistic constructivism. The way in which reality appears in art must not be regarded on its own. It is affected by many other systems of recognizing reality, including the political, religious, economic, intellectual, and social -- in short, all the phenomena of human life. Moreover, art is always of a certain epoch ,with its particular conception of reality. Thus, when discussing, for example, the art of ancient myth, of medieval Christianity, or that of the technological age, one must be aware that myth, Christianity, or technology was the most outstanding feature of the epoch. It is paradoxical to understand art as some kind of copy of the fields of experience connected with it. So, for example, it is meaningless for the work of art to... Question: What can we infer after reading the passage? - The conditions of art are more than a particular way of interpreting reality. - The way in which reality appears in art should be regarded only on its own. - Myth, Christianity, or technology was under the influence of a unique style. - Works of art were usually produced in response to certain interpretations.
Myth, Christianity, or technology was under the influence of a unique style.
