Problem: Copper:

The metal's distinctive natural green patina has long been coveted by architects and designers. The final patina is a particularly durable layer that is highly resistant to atmospheric corrosion, thereby protecting the underlying metal against further weathering. It can be a mixture of carbonate and sulfate compounds in various amounts, depending upon environmental conditions such as sulfur-containing acid rain. Architectural copper and its alloys can also be 'finished' to embark a particular look, feel, and/or color. Finishes include mechanical surface treatments, chemical coloring, and coatings.

What conditions have no influence on the mixture of carbonate and sulfate in copper?

Problem: In Theravada Buddhism there can be no divine salvation or forgiveness for one's karma, since it is a purely impersonal process that is a part of the makeup of the universe.[citation needed] In Mahayana Buddhism, the texts of certain Mahayana sutras (such as the Lotus Sutra, the Angulimaliya Sutra and the Mahayana Mahaparinirvana Sutra) claim that the recitation or merely the hearing of their texts can expunge great swathes of negative karma. Some forms of Buddhism (for example, Vajrayana) regard the recitation of mantras as a means for cutting off of previous negative karma. The Japanese Pure Land teacher Genshin taught that Amitabha has the power to destroy the karma that would otherwise bind one in samsara.
In Mahayana Buddhism, what are some Mahayana sutras that are believed to remove negative karma just by the hearing of the texts?

Answer: the Lotus Sutra, the Angulimaliya Sutra and the Mahayana Mahaparinirvana Sutra

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In ancient Greece, the epics of Homer, who wrote the Iliad and the Odyssey, and Hesiod, who wrote Works and Days and Theogony, are some of the earliest, and most influential, of Ancient Greek literature. Classical Greek genres included philosophy, poetry, historiography, comedies and dramas. Plato and Aristotle authored philosophical texts that are the foundation of Western philosophy, Sappho and Pindar were influential lyric poets, and Herodotus and Thucydides were early Greek historians. Although drama was popular in Ancient Greece, of the hundreds of tragedies written and performed during the classical age, only a limited number of plays by three authors still exist: Aeschylus, Sophocles, and Euripides. The plays of Aristophanes provide the only real examples of a genre of comic drama known as Old Comedy, the earliest form of Greek Comedy, and are in fact used to define the genre.
Who were two important Classic Greek lyric poets?
A: Sappho and Pindar
