Here is a question about this article: The production for sulfidic zinc ores produces large amounts of sulfur dioxide and cadmium vapor. Smelter slag and other residues of process also contain significant amounts of heavy metals. About 1.1 million tonnes of metallic zinc and 130 thousand tonnes of lead were mined and smelted in the Belgian towns of La Calamine and Plombieres between 1806 and 1882. The dumps of the past mining operations leach significant amounts of zinc and cadmium, and, as a result, the sediments of the Geul River contain significant amounts of heavy metals. About two thousand years ago emissions of zinc from mining and smelting totaled 10 thousand tonnes a year. After increasing 10-fold from 1850, zinc emissions peaked at 3.4 million tonnes per year in the 1980s and declined to 2.7 million tonnes in the 1990s, although a 2005 study of the Arctic troposphere found that the concentrations there did not reflect the decline. Anthropogenic and natural emissions occur at a ratio of 20 to 1.
What is the answer to this question: Large amounts of sulfur dioxide and cadmium vapor are produced due to what?
****
So... The production for sulfidic zinc ores

At the end of November, Chopin returned to Paris. He passed the winter in unremitting illness, but gave occasional lessons and was visited by friends, including Delacroix and Franchomme. Occasionally he played, or accompanied the singing of Delfina Potocka, for his friends. During the summer of 1849, his friends found him an apartment in Chaillot, out of the centre of the city, for which the rent was secretly subsidised by an admirer, Princess Obreskoff. Here in June 1849 he was visited by Jenny Lind.
In 1849 where did Chopin live?
****
The answer: Chaillot

Problem: Please answer a question about the following article about Philosophy of space and time:
In Book 11 of St. Augustine's Confessions, he ruminates on the nature of time, asking, "What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not." He goes on to comment on the difficulty of thinking about time, pointing out the inaccuracy of common speech: "For but few things are there of which we speak properly; of most things we speak improperly, still the things intended are understood." But Augustine presented the first philosophical argument for the reality of Creation (against Aristotle) in the context of his discussion of time, saying that knowledge of time depends on the knowledge of the movement of things, and therefore time cannot be where there are no creatures to measure its passing (Confessions Book XI 30; City of God Book XI ch.6).
What did Augustine say that the knowledge of time depended on?
A: the knowledge of the movement of things

Question: Read this and answer the question

The Muslim population of the region consisted mainly of native Iberian converts to Islam (the so-called Muwallad or Muladi) and to a lesser extent Berbers and Arabs. The Arabs were principally noblemen from Oman; and though few in numbers, they constituted the elite of the population. The Berbers were originally from the Atlas mountains and Rif mountains of North Africa and were essentially nomads. In Portugal, the Muslim population (or "Moors"), relatively small in numbers, stayed in the Algarve region, and south of the Tagus. Today, there are approximately 800 words in the Portuguese language of Arabic origin. The Muslims were expelled from Portugal 300 years earlier than in neighbouring Spain, which is reflected both in Portuguese culture and the language, which is mostly Celtiberian and Vulgar Latin.

Where were the Berbers originally from?
Answer: Atlas mountains and Rif mountains of North Africa

Input: Article: The A38 dual-carriageway runs from east to west across the north of the city. Within the city it is designated as 'The Parkway' and represents the boundary between the urban parts of the city and the generally more recent suburban areas. Heading east, it connects Plymouth to the M5 motorway about 40 miles (65 km) away near Exeter; and heading west it connects Cornwall and Devon via the Tamar Bridge. Regular bus services are provided by Plymouth Citybus, First South West and Target Travel. There are three Park and ride services located at Milehouse, Coypool (Plympton) and George Junction (Plymouth City Airport), which are operated by First South West.

Now answer this question: What bridge connects Cornwall to Plymouth via the A38?

Output:
Tamar Bridge
