1. What are frostquakes?

2. How do you drive in floods?
Answer: Stay out of water more than six inches deep. Drive slowly in a low gear with high revs to prevent water entering the exhaust.

3. What does Boko Haram mean?
Answer: "Haram" means forbidden in Arabic, while the Hausa language phrase "ilimin boko", denoting the style of schooling created in Nigeria by colonialists, was shortened to "boko" and has come to mean Western-style education. So "Western education is a sin" is a workable translation.

5. What language did Jesus speak?

6. Why does the sum 7x8 catch people out?
Answer: UK Chancellor George Osborne refused to attempt this mathematical question, which had embarrassingly flummoxed Labour's Stephen Byers in the late 1990s. "I've made it a rule in life not to answer," the man in charge of the economy told a group of children who interviewed him in July. But research has found that 7x8 is only the seventh hardest multiplication sum, with 6x8 throwing most people.
7. Where does the phrase 'boots on the ground' come from?
Answer: The word "boot", a synecdoche (a figure of speech where the part represents the whole) meaning soldier, was used as long ago as World War One. The earliest known use of the full expression "boots on the ground" came in 1980, in a story in the Christian Science Monitor about the Iran hostage crisis.
Now that may be the truth of where the phrase came from but in fact the man who over uses the phrase is the special envoy to the Middle East one Mr Tony Blair.
