[Q]: The Sahel (/ səˈhɛl /) is the ecoclimatic and biogeographic zone of transition in Africa between the Sahara to the north and the Sudanian Savanna to the south. Having a semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The name is derived from the Arabic word sāḥil (ساحل, Arabic pronunciation: (ˈsaːħil)) meaning 'coast' or 'shore' in a figurative sense (in reference to the southern edge of the vast Sahara), while the name Swahili means 'coastal (dweller)' in a literal sense.

[Q]: Thompson remains best known for Fear and Loathing in Las Vegas (1971), a book first serialized in Rolling Stone in which he grapples with the implications of what he considered the failure of the 1960s counterculture movement. It was adapted on film twice: loosely in Where the Buffalo Roam starring Bill Murray as Thompson in 1980, and directly in 1998 by director Terry Gilliam in film starring Johnny Depp and Benicio del Toro. The Doonesbury cartoon character Duke -- who was modeled after Thompson -- pens an essay about 'my shoplifting conviction' entitled 'Fear and Loathing at Macy's Menswear', an obvious reference to Thompson's book.

The first windshield cleaner unit offered for automobiles was in 1936, as an aftermarket option to be installed on cars after they were bought.
