Passage Summary: If you combine the features of a 'beautiful' style with the features of a 'dramatic' style, the resulting hybrid will definitely be both beautiful and dramatic.

Conclusion: A new architectural style that merges classical Roman and postmodern elements will be both beautiful and dramatic.

Reasoning: Classical Roman architecture is beautiful because of its arches and symmetry, while postmodern architecture is dramatic because of its materials and environment.

Analysis: This argument commits a 'fallacy of composition,' assuming that what is true of the parts must be true of the whole. It's like saying that because chocolate is delicious and lobster is delicious, a chocolate-covered lobster must be a culinary masterpiece. The combination of these architectural elements might actually result in a cluttered mess that loses the beauty of the symmetry and the drama of the materials. Look for an answer that points out that combining elements can change or negate their original effects.
