Question: Drama is literature intended for performance. The form is often combined with music and dance, as in opera and musical theatre. A play is a subset of this form, referring to the written dramatic work of a playwright that is intended for performance in a theatre; it comprises chiefly dialogue between characters, and usually aims at dramatic or theatrical performance rather than at reading. A closet drama, by contrast, refers to a play written to be read rather than to be performed; hence, it is intended that the meaning of such a work can be realized fully on the page. Nearly all drama took verse form until comparatively recently.

Question: Tobacco smoking (including secondhand smoke) and short-term exposure to air pollution such as carbon monoxide, nitrogen dioxide, and sulfur dioxide (but not ozone) have been associated with MI. Other factors that increase the risk of MI and are associated with worse outcomes after an MI include lack of physical activity and psychosocial factors including low socioeconomic status, social isolation, and negative emotions. Shift work is also associated with a higher risk of MI. Acute and prolonged intake of high quantities of alcoholic drinks (3-4 or more) increase the risk of a heart attack.

Question: In 2013, China led the world in renewable energy production, with a total capacity of 378 GW, mainly from hydroelectric and wind power. As of 2014, China leads the world in the production and use of wind power, solar photovoltaic power and smart grid technologies, generating almost as much water, wind and solar energy as all of France and Germany's power plants combined. China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity. Since 2005, production of solar cells in China has expanded 100-fold. As Chinese renewable manufacturing has grown, the costs of renewable energy technologies have dropped. Innovation has helped, but the main driver of reduced costs has been market expansion.
Is there an answer to this question: What is not the main driver of reduced costs?

Answer: unanswerable
