A prime minister is the most senior minister of cabinet in the executive branch of government, often in a parliamentary or semi-presidential system. In many systems, the prime minister selects and may dismiss other members of the cabinet, and allocates posts to members within the government. In most systems, the prime minister is the presiding member and chairman of the cabinet. In a minority of systems, notably in semi-presidential systems of government, a prime minister is the official who is appointed to manage the civil service and execute the directives of the head of state.
What branch of government does the prime minister lead?
****
The answer: executive

Napoleon maintained strict, efficient work habits, prioritizing what needed to be done. He cheated at cards, but repaid the losses; he had to win at everything he attempted. He kept relays of staff and secretaries at work. Unlike many generals, Napoleon did not examine history to ask what Hannibal or Alexander or anyone else did in a similar situation. Critics said he won many battles simply because of luck; Napoleon responded, "Give me lucky generals," aware that "luck" comes to leaders who recognize opportunity, and seize it. Dwyer argues that Napoleon's victories at Austerlitz and Jena in 1805-06 heightened his sense of self-grandiosity, leaving him even more certain of his destiny and invincibility. By the Russian campaign in 1812, however, Napoleon seems to have lost his verve. With crisis after crisis at hand, he rarely rose to the occasion. Some historians have suggested a physical deterioration, but others note that an impaired Napoleon was still a brilliant general.
According to critics, what was the reason Napoleon won many battles?
****
The answer: luck

Solar chemical processes use solar energy to drive chemical reactions. These processes offset energy that would otherwise come from a fossil fuel source and can also convert solar energy into storable and transportable fuels. Solar induced chemical reactions can be divided into thermochemical or photochemical. A variety of fuels can be produced by artificial photosynthesis. The multielectron catalytic chemistry involved in making carbon-based fuels (such as methanol) from reduction of carbon dioxide is challenging; a feasible alternative is hydrogen production from protons, though use of water as the source of electrons (as plants do) requires mastering the multielectron oxidation of two water molecules to molecular oxygen. Some have envisaged working solar fuel plants in coastal metropolitan areas by 2050 the splitting of sea water providing hydrogen to be run through adjacent fuel-cell electric power plants and the pure water by-product going directly into the municipal water system. Another vision involves all human structures covering the earth's surface (i.e., roads, vehicles and buildings) doing photosynthesis more efficiently than plants.
What is a possible alternative to making carbon-based fuels from reduction of carbon dioxide?
****
The answer:
hydrogen production from protons
