The problem: Answer a question about this article:
The Eastern Roman Empire – today conventionally named the Byzantine Empire, a name not in use during its own time – became increasingly influenced by Greek culture after the 7th century, when Emperor Heraclius (AD 575 - 641) decided to make Greek the empire's official language. Certainly from then on, but likely earlier, the Roman and Greek cultures were virtually fused into a single Greco-Roman world. Although the Latin West recognized the Eastern Empire's claim to the Roman legacy for several centuries, after Pope Leo III crowned Charlemagne, king of the Franks, as the "Roman Emperor" on 25 December 800, an act which eventually led to the formation of the Holy Roman Empire, the Latin West started to favour the Franks and began to refer to the Eastern Roman Empire largely as the Empire of the Greeks (Imperium Graecorum).
What decision did he make that influenced the culture in an attempt to make things more homogeneous ?
****
The answer: decided to make Greek the empire's official language.


Problem: Please answer a question about the following article about Eritrea:
Even during the war, Eritrea developed its transportation infrastructure by asphalting new roads, improving its ports, and repairing war-damaged roads and bridges as a part of the Warsay Yika'alo Program. The most significant of these projects was the construction of a coastal highway of more than 500 km connecting Massawa with Asseb, as well as the rehabilitation of the Eritrean Railway. The rail line has been restored between the port of Massawa and the capital Asmara, although services are sporadic. Steam locomotives are sometimes used for groups of enthusiasts.
How long was the coastal highway between Massawa and Asseb?
A: more than 500 km

On 26 February 2012, The Sun on Sunday was launched to replace the closed News of the World, employing some of its former journalists. In late 2013, it was given a new look, with a new typeface. The average circulation for The Sun on Sunday in March 2014 was 1,686,840; but in May 2015 The Mail on Sunday sold more copies for the first time, an average of 28,650 over those of its rival: 1,497,855 to 1,469,195. Roy Greenslade issued some caveats over the May 2015 figures, but believes the weekday Daily Mail will overtake The Sun in circulation during 2016.

In what year was The Sun's look changed?
Answer: 2013


Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.
The sand and clay deposited onto decaying marine matter transformed into what?

oil and natural gas
