Hunting-gathering was the common human mode of subsistence throughout the Paleolithic, but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How do modern hunters and gathers differ from early ones?
Ah, so.. contact with modern civilization

The Maya writing system (often called hieroglyphs from a superficial resemblance to the Ancient Egyptian writing) was a combination of phonetic symbols and logograms. It is most often classified as a logographic or (more properly) a logosyllabic writing system, in which syllabic signs play a significant role. It is the only pre-Columbian writing system known to represent completely the spoken language of its community. In total, the script has more than one thousand different glyphs although a few are variations of the same sign or meaning and many appear only rarely or are confined to particular localities. At any one time, no more than about five hundred glyphs were in use, some two hundred of which (including variations) had a phonetic or syllabic interpretation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the Mayan writing system the only known pre-Columbian one to completely represent this?
Ah, so.. spoken language of its community

Charlemagne planned to continue the Frankish tradition of dividing his kingdom between all his heirs, but was unable to do so as only one son, Louis the Pious (r. 814–840), was still alive by 813. Just before Charlemagne died in 814, he crowned Louis as his successor. Louis's reign of 26 years was marked by numerous divisions of the empire among his sons and, after 829, civil wars between various alliances of father and sons over the control of various parts of the empire. Eventually, Louis recognised his eldest son Lothair I (d. 855) as emperor and gave him Italy. Louis divided the rest of the empire between Lothair and Charles the Bald (d. 877), his youngest son. Lothair took East Francia, comprising both banks of the Rhine and eastwards, leaving Charles West Francia with the empire to the west of the Rhineland and the Alps. Louis the German (d. 876), the middle child, who had been rebellious to the last, was allowed to keep Bavaria under the suzerainty of his elder brother. The division was disputed. Pepin II of Aquitaine (d. after 864), the emperor's grandson, rebelled in a contest for Aquitaine, while Louis the German tried to annex all of East Francia. Louis the Pious died in 840, with the empire still in chaos.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who ruled Italy after Louis the Pious?
Ah, so..
Lothair I
