Input: Article: The Quran most likely existed in scattered written form during Muhammad's lifetime. Several sources indicate that during Muhammad's lifetime a large number of his companions had memorized the revelations. Early commentaries and Islamic historical sources support the above-mentioned understanding of the Quran's early development. The Quran in its present form is generally considered by academic scholars to record the words spoken by Muhammad because the search for variants has not yielded any differences of great significance.[page needed] University of Chicago professor Fred Donner states that "...there was a very early attempt to establish a uniform consonantal text of the Quran from what was probably a wider and more varied group of related texts in early transmission. [...] After the creation of this standardized canonical text, earlier authoritative texts were suppressed, and all extant manuscriptsdespite their numerous variantsseem to date to a time after this standard consonantal text was established." Although most variant readings of the text of the Quran have ceased to be transmitted, some still are. There has been no critical text produced on which a scholarly reconstruction of the Quranic text could be based. Historically, controversy over the Quran's content has rarely become an issue, although debates continue on the subject.

Now answer this question: Who had begun memorizing Muhammad's revelations in his lifetime?

Output: his companions

Article: The location and terrain of Kathmandu have played a significant role in the development of a stable economy which spans millennia. The city is located in an ancient lake basin, with fertile soil and flat terrain. This geography helped form a society based on agriculture. This, combined with its location between India and China, helped establish Kathmandu as an important trading center over the centuries. Kathmandu's trade is an ancient profession that flourished along an offshoot of the Silk Road which linked India and Tibet. From centuries past, Lhasa Newar merchants of Kathmandu have conducted trade across the Himalaya and contributed to spreading art styles and Buddhism across Central Asia. Other traditional occupations are farming, metal casting, woodcarving, painting, weaving, and pottery.

Question: Existing between what two countries contributed to Kathmandu becoming a center of trade?
Ans: India and China

Here is a question about this article: Beyonce's vocal range spans four octaves. Jody Rosen highlights her tone and timbre as particularly distinctive, describing her voice as "one of the most compelling instruments in popular music". While another critic says she is a "Vocal acrobat, being able to sing long and complex melismas and vocal runs effortlessly, and in key. Her vocal abilities mean she is identified as the centerpiece of Destiny's Child. The Daily Mail calls Beyonce's voice "versatile", capable of exploring power ballads, soul, rock belting, operatic flourishes, and hip hop. Jon Pareles of The New York Times commented that her voice is "velvety yet tart, with an insistent flutter and reserves of soul belting". Rosen notes that the hip hop era highly influenced Beyonce's strange rhythmic vocal style, but also finds her quite traditionalist in her use of balladry, gospel and falsetto. Other critics praise her range and power, with Chris Richards of The Washington Post saying she was "capable of punctuating any beat with goose-bump-inducing whispers or full-bore diva-roars."
What is the answer to this question: New York Times' Jon Pareles calls Beyonce's voice velvety yet what?
****
So... tart

The problem: Answer a question about this article:
When in choir dress, a Latin-rite cardinal wears scarlet garments the blood-like red symbolizes a cardinal's willingness to die for his faith. Excluding the rochet which is always white the scarlet garments include the cassock, mozzetta, and biretta (over the usual scarlet zucchetto). The biretta of a cardinal is distinctive not merely for its scarlet color, but also for the fact that it does not have a pompon or tassel on the top as do the birettas of other prelates. Until the 1460s, it was customary for cardinals to wear a violet or blue cape unless granted the privilege of wearing red when acting on papal business. His normal-wear cassock is black but has scarlet piping and a scarlet fascia (sash). Occasionally, a cardinal wears a scarlet ferraiolo which is a cape worn over the shoulders, tied at the neck in a bow by narrow strips of cloth in the front, without any 'trim' or piping on it. It is because of the scarlet color of cardinals' vesture that the bird of the same name has become known as such.[citation needed]
What does the color red symbolize in the clothing worn by Cardinals?
****
The answer: willingness to die for his faith

Problem: Please answer a question about the following article about Police:
They can also be armed with non-lethal (more accurately known as "less than lethal" or "less-lethal") weaponry, particularly for riot control. Non-lethal weapons include batons, tear gas, riot control agents, rubber bullets, riot shields, water cannons and electroshock weapons. Police officers often carry handcuffs to restrain suspects. The use of firearms or deadly force is typically a last resort only to be used when necessary to save human life, although some jurisdictions (such as Brazil) allow its use against fleeing felons and escaped convicts. A "shoot-to-kill" policy was recently introduced in South Africa, which allows police to use deadly force against any person who poses a significant threat to them or civilians. With the country having one of the highest rates of violent crime, president Jacob Zuma states that South Africa needs to handle crime differently from other countries.
What are common less-lethal weapons?
A: batons, tear gas, riot control agents, rubber bullets, riot shields, water cannons and electroshock weapons

Question: Read this and answer the question

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 is the process that plants undergo in order to obtain carbohydrates?
Answer:
photosynthesis
