(a) Almost all of the fossil fuels that we are now currently using were formed during the Carboniferous period. Ture or False?

(b) There seems to be a strong correlation between increases in the availability of food energy per person and increases in human population, at least up until very recent years. Ture or False?

(c) By the end of the Neolithic Period some 6000 years ago, there were roughly 10 million humans on earth and almost all of them were using probably 12,000 kilocalories per person per day. Ture or False?

(d) By about 500 AD, the Roman Empire had disintegrated and the human population n earth may have been about 200 million people. Some of those people may have been using 26,000 kilocalories per person per day, but many were still living in more primitive, Stone Age conditions and using significantly less energy per person. Ture or False?

(e) The vacuum steam pump developed by Thomas Savery converted less than 1 percent of its input energy into useful work. By the 1950's, combined cycle steam turbines had achieved efficiencies of 54 percent. Ture or False?

(f) By 1900, there were about 1.6 billion people on earth who were using, on average, about 3.7 million megawatt-hours of inamimate energy per person per year. Ture or False?

(g) In the 1990's,the United States, with only about 4.7 percent of the world's people, used over a third of the world's energy, using enough energy per person to sustain about 92 of the world's poorest people. Ture or False?

(h) Just like the population of the reindeer herd that was introduced to St. Matthew Island collapsed once it passed 6000, the world's population is about to collapse now that it has passed 6000 million people. Ture or False?
