Article: By 500 BCE, Greeks arrived in the desert. Greek traders spread along the eastern coast of the desert, establishing trading colonies along the Red Sea. The Carthaginians explored the Atlantic coast of the desert, but the turbulence of the waters and the lack of markets caused a lack of presence further south than modern Morocco. Centralized states thus surrounded the desert on the north and east; it remained outside the control of these states. Raids from the nomadic Berber people of the desert were a constant concern of those living on the edge of the desert.

Question: Who would raid the desert leaving the people in constant fear?
Ans: nomadic Berber

Murdoch has responded to some of the arguments against the newspaper by saying that critics are "snobs" who want to "impose their tastes on everyone else", while MacKenzie claims the same critics are people who, if they ever had a "popular idea", would have to "go and lie down in a dark room for half an hour". Both have pointed to the huge commercial success of the Sun in this period and its establishment as Britain's top-selling newspaper, claiming that they are "giving the public what they want". This conclusion is disputed by critics. John Pilger has said that a late-1970s edition of the Daily Mirror, which replaced the usual celebrity and domestic political news items with an entire issue devoted to his own front-line reporting of the genocide in Pol Pot's Cambodia, not only outsold The Sun on the day it was issued but became the only edition of the Daily Mirror to ever sell every single copy issued throughout the country, something never achieved by The Sun.
What did Murdoch and Mackenzie say in defense of The Sun?
****
The answer: they are "giving the public what they want"
