In Iran (Persia), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran. In Persian poets' poems, especially Ferdowsi's Shahname, there are references to cotton ("panbe" in Persian). Marco Polo (13th century) refers to the major products of Persia, including cotton. John Chardin, a French traveler of the 17th century who visited the Safavid Persia, spoke approvingly of the vast cotton farms of Persia.
What 13th century explorer saw cotton in Persia?
Marco Polo

Input: Energy
Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.

What transforms nuclear potential energy to other forms of energy?
Output: Sun

Input: Article: Medical facilities in Mali are very limited, and medicines are in short supply. Malaria and other arthropod-borne diseases are prevalent in Mali, as are a number of infectious diseases such as cholera and tuberculosis. Mali's population also suffers from a high rate of child malnutrition and a low rate of immunization. An estimated 1.9 percent of the adult and children population was afflicted with HIV/AIDS that year, among the lowest rates in Sub-Saharan Africa. An estimated 8591 percent of Mali's girls and women have had female genital mutilation (2006 and 2001 data).

Now answer this question: What Sexually transmitted disease afflicts roughly 1.9 percent of the population?

Output: HIV/AIDS

Article: Marvel held its own comic book convention, Marvelcon '75, in spring 1975, and promised a Marvelcon '76. At the 1975 event, Stan Lee used a Fantastic Four panel discussion to announce that Jack Kirby, the artist co-creator of most of Marvel's signature characters, was returning to Marvel after having left in 1970 to work for rival DC Comics. In October 1976, Marvel, which already licensed reprints in different countries, including the UK, created a superhero specifically for the British market. Captain Britain debuted exclusively in the UK, and later appeared in American comics.

Question: What Marvel character was specifically created to appeal to the UK market?
Ans: Captain Britain

Here is a question about this article: By the early 19th century, encouraged by lower duties on gin, the gin houses or "Gin Palaces" had spread from London to most cities and towns in Britain, with most of the new establishments illegal and unlicensed. These bawdy, loud and unruly drinking dens so often described by Charles Dickens in his Sketches by Boz (published 18351836) increasingly came to be held as unbridled cesspits of immorality or crime and the source of much ill-health and alcoholism among the working classes.
What is the answer to this question: In what British city did gin houses first appear?
****
So... London

Article: These areas contain some spectacular scenery as well, as evidenced by such national parks as Yosemite and Mount Rainier. West of the Cascades and Sierra Nevada is a series of valleys, such as the Central Valley in California and the Willamette Valley in Oregon. Along the coast is a series of low mountain ranges known as the Pacific Coast Ranges. Much of the Pacific Northwest coast is inhabited by some of the densest vegetation outside of the Tropics, and also the tallest trees in the world (the Redwoods).

Question: What are the low mountain ranges that are located along the pacific coast called?
Ans:
Pacific Coast Ranges
