Problem: Jobs stated during the Macintosh's introduction "we expect Macintosh to become the third industry standard", after the Apple II and IBM PC. Although outselling every other computer, it did not meet expectations during the first year, especially among business customers. Only about ten applications including MacWrite and MacPaint were widely available, although many non-Apple software developers participated in the introduction and Apple promised that 79 companies including Lotus, Digital Research, and Ashton-Tate were creating products for the new computer. After one year, it had less than one quarter of the software selection available compared to the IBM PC—including only one word processor, two databases, and one spreadsheet—although Apple had sold 280,000 Macintoshes compared to IBM's first year sales of fewer than 100,000 PCs.
How many companies did Apple promise were develping products for the new computer?
The answer is the following: 79

Problem: The son of an impoverished Bedouin goat herder, Gaddafi became involved in politics while at school in Sabha, subsequently enrolling in the Royal Military Academy, Benghazi. Founding a revolutionary cell within the military, in 1969 they seized power from the absolute monarchy of King Idris in a bloodless coup. Becoming Chairman of the governing Revolutionary Command Council (RCC), Gaddafi abolished the monarchy and proclaimed the Republic. Ruling by decree, he implemented measures to remove what he viewed as foreign imperialist influence from Libya, and strengthened ties to Arab nationalist governments. Intent on pushing Libya towards "Islamic socialism", he introduced sharia as the basis for the legal system and nationalized the oil industry, using the increased revenues to bolster the military, implement social programs and fund revolutionary militants across the world. In 1973 he initiated a "Popular Revolution" with the formation of General People's Committees (GPCs), purported to be a system of direct democracy, but retained personal control over major decisions. He outlined his Third International Theory that year, publishing these ideas in The Green Book.
How did Gaddafi use all the money that resulted from nationalizing the oil industry?
The answer is the following: to bolster the military, implement social programs and fund revolutionary militants across the world.

Problem: Total investment in renewable energy (including small hydro-electric projects) was $244 billion in 2012, down 12% from 2011 mainly due to dramatically lower solar prices and weakened US and EU markets. As a share of total investment in power plants, wind and solar PV grew from 14% in 2000 to over 60% in 2012. The top countries for investment in recent years were China, Germany, Spain, the United States, Italy, and Brazil. Renewable energy companies include BrightSource Energy, First Solar, Gamesa, GE Energy, Goldwind, Sinovel, Trina Solar, Vestas and Yingli.
What  six were the top countries for investment in recent years?
The answer is the following: China, Germany, Spain, the United States, Italy, and Brazil

Problem: Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a PMSM. The rotor material, like that of a common nail, will stay magnetized, but can also be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.
When in operation, what do hysteresis synchronous motors poles do?
The answer is the following:
stay in place
