Problem: Please answer a question about the following article about Nutrition:
Plants uptake essential elements from the soil through their roots and from the air (consisting of mainly nitrogen and oxygen) through their leaves. Green plants obtain their carbohydrate supply from the carbon dioxide in the air by the process of photosynthesis. Carbon and oxygen are absorbed from the air, while other nutrients are absorbed from the soil. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root. In the leaves, stomata open to take in carbon dioxide and expel oxygen. The carbon dioxide molecules are used as the carbon source in photosynthesis.
What part of the leaf in a plant takes in carbon dioxide and releases oxygen?
A: stomata

Nurhaci declared himself the "Bright Khan" of the Later Jin (lit. "gold") state in honor both of the 1213th century Jurchen Jin dynasty and of his Aisin Gioro clan (Aisin being Manchu for the Chinese (jin, "gold")). His son Hong Taiji renamed the dynasty Great Qing in 1636. There are competing explanations on the meaning of Qing (lit. "clear" or "pure"). The name may have been selected in reaction to the name of the Ming dynasty (), which consists of the Chinese characters for "sun" () and "moon" (), both associated with the fire element of the Chinese zodiacal system. The character Qing () is composed of "water" () and "azure" (), both associated with the water element. This association would justify the Qing conquest as defeat of fire by water. The water imagery of the new name may also have had Buddhist overtones of perspicacity and enlightenment and connections with the Bodhisattva Manjusri. The Manchu name daicing, which sounds like a phonetic rendering of Da Qing or Dai Ching, may in fact have been derived from a Mongolian word that means "warrior". Daicing gurun may therefore have meant "warrior state", a pun that was only intelligible to Manchu and Mongol people. In the later part of the dynasty, however, even the Manchus themselves had forgotten this possible meaning.

Who named himself the Bright Khan?
Answer: Nurhaci

Problem: The Obama administration began to reengage in Iraq with a series of airstrikes aimed at ISIS beginning on 10 August 2014. On 9 September 2014 President Obama said that he had the authority he needed to take action to destroy the militant group known as the Islamic State of Iraq and the Levant, citing the 2001 Authorization for Use of Military Force Against Terrorists, and thus did not require additional approval from Congress. The following day on 10 September 2014 President Barack Obama made a televised speech about ISIL, which he stated "Our objective is clear: We will degrade, and ultimately destroy, ISIL through a comprehensive and sustained counter-terrorism strategy". Obama has authorized the deployment of additional U.S. Forces into Iraq, as well as authorizing direct military operations against ISIL within Syria. On the night of 21/22 September the United States, Saudi Arabia, Bahrain, the UAE, Jordan and Qatar started air attacks against ISIS in Syria.[citation needed]
When did Obama make a speech about ISIS on TV?
The answer is the following: 10 September 2014

Translations of sung textswhether of the above type meant to be sung or of a more or less literal type meant to be readare also used as aids to audiences, singers and conductors, when a work is being sung in a language not known to them. The most familiar types are translations presented as subtitles or surtitles projected during opera performances, those inserted into concert programs, and those that accompany commercial audio CDs of vocal music. In addition, professional and amateur singers often sing works in languages they do not know (or do not know well), and translations are then used to enable them to understand the meaning of the words they are singing.
Who can translations of a sung text aid?
audiences, singers and conductors
