Input: Article: Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.

Now answer this question: What type of furnace was functional in China in 722 BC?

Output: blast

Article: Spanish mendicants in the sixteenth century taught indigenous scribes in their communities to write their languages in Latin letters and there is a large number of local-level documents in Nahuatl, Zapotec, Mixtec, and Yucatec Maya from the colonial era, many of which were part of lawsuits and other legal matters. Although Spaniards initially taught indigenous scribes alphabetic writing, the tradition became self-perpetuating at the local level. The Spanish crown gathered such documentation and contemporary Spanish translations were made for legal cases. Scholars have translated and analyzed these documents in what is called the New Philology to write histories of indigenous peoples from indigenous viewpoints.

Question: When were indigenous scribes taught to use Latin letters?
Ans: the sixteenth century

The problem: Answer a question about this article:
The ranging signals are based on the CDMA principle and have complex structure typical of Galileo or modernized GPS. Similar to the other GNSS, there will be two levels of positioning service: open and restricted (military). The public service shall be available globally to general users. When all the currently planned GNSS systems are deployed, the users will benefit from the use of a total constellation of 75+ satellites, which will significantly improve all the aspects of positioning, especially availability of the signals in so-called urban canyons. The general designer of the COMPASS navigation system is Sun Jiadong, who is also the general designer of its predecessor, the original BeiDou navigation system.
How many satellites will the COMPASS navigation system use?
****
The answer: 75+ satellites

Problem: Please answer a question about the following article about Unicode:
In terms of the newline, Unicode introduced U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR. This was an attempt to provide a Unicode solution to encoding paragraphs and lines semantically, potentially replacing all of the various platform solutions. In doing so, Unicode does provide a way around the historical platform dependent solutions. Nonetheless, few if any Unicode solutions have adopted these Unicode line and paragraph separators as the sole canonical line ending characters. However, a common approach to solving this issue is through newline normalization. This is achieved with the Cocoa text system in Mac OS X and also with W3C XML and HTML recommendations. In this approach every possible newline character is converted internally to a common newline (which one does not really matter since it is an internal operation just for rendering). In other words, the text system can correctly treat the character as a newline, regardless of the input's actual encoding.
How is newline normalization accomplished in Mac OS X?
A: Cocoa text system

Question: Read this and answer the question

After Alexander the Great's ventures in the Persian Empire, Hellenistic kingdoms were established throughout south-west Asia (Seleucid Empire, Kingdom of Pergamon), north-east Africa (Ptolemaic Kingdom) and South Asia (Greco-Bactrian Kingdom, Indo-Greek Kingdom). This resulted in the export of Greek culture and language to these new realms through Greco-Macedonian colonization, spanning as far as modern-day Pakistan. Equally, however, these new kingdoms were influenced by the indigenous cultures, adopting local practices where beneficial, necessary, or convenient. Hellenistic culture thus represents a fusion of the Ancient Greek world with that of the Near East, Middle East, and Southwest Asia, and a departure from earlier Greek attitudes towards "barbarian" cultures. The Hellenistic period was characterized by a new wave of Greek colonization (as distinguished from that occurring in the 8th6th centuries BC) which established Greek cities and kingdoms in Asia and Africa. Those new cities were composed of Greek colonists who came from different parts of the Greek world, and not, as before, from a specific "mother city". The main cultural centers expanded from mainland Greece to Pergamon, Rhodes, and new Greek colonies such as Seleucia, Antioch, Alexandria and Ai-Khanoum. This mixture of Greek-speakers gave birth to a common Attic-based dialect, known as Koine Greek, which became the lingua franca through the Hellenistic world.

Where was the Ptolemaic Kingdom located?
Answer:
north-east Africa
