Problem: Jews:

According to the Hebrew Bible narrative, Jewish ancestry is traced back to the Biblical patriarchs such as Abraham, Isaac and Jacob, and the Biblical matriarchs Sarah, Rebecca, Leah, and Rachel, who lived in Canaan around the 18th century BCE. Jacob and his family migrated to Ancient Egypt after being invited to live with Jacob's son Joseph by the Pharaoh himself. The patriarchs' descendants were later enslaved until the Exodus led by Moses, traditionally dated to the 13th century BCE, after which the Israelites conquered Canaan.[citation needed]

Who led the Exodus?

A: Moses

Problem: However, the battle was one-sided almost from the beginning. The reasons for this are the subject of continuing study by military strategists and academics. There is general agreement that US technological superiority was a crucial factor but the speed and scale of the Iraqi collapse has also been attributed to poor strategic and tactical leadership and low morale among Iraqi troops, which resulted from a history of incompetent leadership. After devastating initial strikes against Iraqi air defenses and command and control facilities on 17 January 1991, coalition forces achieved total air superiority almost immediately. The Iraqi air force was destroyed within a few days, with some planes fleeing to Iran, where they were interned for the duration of the conflict. The overwhelming technological advantages of the US, such as stealth aircraft and infrared sights, quickly turned the air war into a "turkey shoot". The heat signature of any tank which started its engine made an easy target. Air defense radars were quickly destroyed by radar-seeking missiles fired from wild weasel aircraft. Grainy video clips, shot from the nose cameras of missiles as they aimed at impossibly small targets, were a staple of US news coverage and revealed to the world a new kind of war, compared by some to a video game. Over 6 weeks of relentless pounding by planes and helicopters, the Iraqi army was almost completely beaten but did not retreat, under orders from Iraqi President Saddam Hussein, and by the time the ground forces invaded on 24 February, many Iraqi troops quickly surrendered to forces much smaller than their own; in one instance, Iraqi forces attempted to surrender to a television camera crew that was advancing with coalition forces.

While attending Ealing Art College, Tim Staffell became friends with Farrokh Bulsara, a fellow student who had assumed the English name of Freddie. Bulsara felt that he and the band had the same tastes and soon became a keen fan of Smile. In late 1970, after Staffell left to join the band Humpy Bong, the remaining Smile members, encouraged by Bulsara, changed their name to "Queen" and continued working together. When asked about the name, Bulsara explained, "I thought up the name Queen. It's just a name, but it's very regal obviously, and it sounds splendid. It's a strong name, very universal and immediate. It had a lot of visual potential and was open to all sorts of interpretations. I was certainly aware of gay connotations, but that was just one facet of it."
What band did Tim Staffell join after leaving Smile?
A: Humpy Bong
