Problem: Tucson has a desert climate (Köppen BWh), with two major seasons, summer and winter; plus three minor seasons: fall, spring, and the monsoon. Tucson averages 11.8 inches (299.7 mm) of precipitation per year, more than most other locations with desert climates, but it still qualifies due to its high evapotranspiration; in other words, it experiences a high net loss of water. A similar scenario is seen in Alice Springs, Australia, which averages 11 inches (279.4 mm) a year, but has a desert climate.
What other city is similar to Tuscon in precipitation and climate?
---
Answer: Alice Springs

Problem: In 1937 over 100 people died after ingesting "Elixir Sulfanilamide" manufactured by S.E. Massengill Company of Tennessee. The product was formulated in diethylene glycol, a highly toxic solvent that is now widely used as antifreeze. Under the laws extant at that time, prosecution of the manufacturer was possible only under the technicality that the product had been called an "elixir", which literally implied a solution in ethanol. In response to this episode, the U.S. Congress passed the Federal Food, Drug, and Cosmetic Act of 1938, which for the first time required pre-market demonstration of safety before a drug could be sold, and explicitly prohibited false therapeutic claims.
Diethylene glycol is mainly used today as what liquid?

Answer:
antifreeze
