Renewable energy technologies are getting cheaper, through technological change and through the benefits of mass production and market competition. A 2011 IEA report said: "A portfolio of renewable energy technologies is becoming cost-competitive in an increasingly broad range of circumstances, in some cases providing investment opportunities without the need for specific economic support," and added that "cost reductions in critical technologies, such as wind and solar, are set to continue." As of 2011[update], there have been substantial reductions in the cost of solar and wind technologies:
As of what year have there been substantial reductions in the cost of solar and wind technologies?
****
The answer: 2011

On 18 June 1953, the monarchy was abolished and the Republic of Egypt declared, with Naguib as its first president. According to Aburish, after assuming power, Nasser and the Free Officers expected to become the "guardians of the people's interests" against the monarchy and the pasha class while leaving the day-to-day tasks of government to civilians. They asked former prime minister Ali Maher to accept reappointment to his previous position, and to form an all-civilian cabinet. The Free Officers then governed as the Revolutionary Command Council (RCC) with Naguib as chairman and Nasser as vice-chairman. Relations between the RCC and Maher grew tense, however, as the latter viewed many of Nasser's schemes—agrarian reform, abolition of the monarchy, reorganization of political parties—as too radical, culminating in Maher's resignation on 7 September. Naguib assumed the additional role of prime minister, and Nasser that of deputy prime minister. In September, the Agrarian Reform Law was put into effect. In Nasser's eyes, this law gave the RCC its own identity and transformed the coup into a revolution.
What law did Nasser view as the culmination of his revolutionary efforts?
****
The answer: Agrarian Reform Law

Rome's military confederation with the other peoples of the Italian peninsula meant that half of Rome's army was provided by the Socii, such as the Etruscans, Umbrians, Apulians, Campanians, Samnites, Lucani, Bruttii, and the various southern Greek cities. Polybius states that Rome could draw on 770,000 men at the beginning of the Second Punic War, of which 700,000 were infantry and 70,000 met the requirements for cavalry. Rome's Italian allies would be organized in alae, or wings, roughly equal in manpower to the Roman legions, though with 900 cavalry instead of 300.
How many soldiers were available to Rome at the start of the Second Punic War?
****
The answer: 770,000 men

By the early 18th century, the Maratha Kingdom had transformed itself into the Maratha Empire under the rule of the Peshwas (prime ministers). In 1737, the Marathas defeated a Mughal army in their capital, Delhi itself in Battle of Delhi (1737). The Marathas continued their military campaigns against Mughals, Nizam, Nawab of Bengal and Durrani Empire to further extend their boundaries. Gordon explained how the Maratha systematically took control over new regions. They would start with annual raids, followed by collecting ransom from villages and towns while the declining Mughal Empire retained nominal control and finally taking over the region. He explained it with the example of Malwa region. Marathas built an efficient system of public administration known for its attention to detail. It succeeded in raising revenue in districts that recovered from years of raids, up to levels previously enjoyed by the Mughals. For example, the cornerstone of the Maratha rule in Malwa rested on the 60 or so local tax collectors who advanced the Maratha ruler Peshwa a portion of their district revenues at interest. By 1760, the domain of the Marathas stretched across practically the entire subcontinent. The north-western expansion of the Marathas was stopped after the Third Battle of Panipat (1761). However, the Maratha authority in the north was re-established within a decade under Peshwa Madhavrao I. The defeat of Marathas by British in third Anglo-Maratha Wars brought end to the empire by 1820. The last peshwa, Baji Rao II, was defeated by the British in the Third Anglo-Maratha War. With the defeat of the Marathas, no native power represented any significant threat for the British afterwards.
In the end, what empire defeated the Maratha Empire?
****
The answer:
British
