[Q]: Question: How deep were their heavy infantry formations normally? Passage:Having recovered from their losses at Trebia (218 BC) and Lake Trasimene (217 BC), the Romans decided to engage Hannibal at Cannae, with approximately 86,000 Roman and allied troops. They massed their heavy infantry in a deeper formation than usual, while Hannibal used the double envelopment tactic and surrounded his enemy, trapping the majority of the Roman army, who were then slaughtered. The loss of life on the Roman side was one of the most lethal single day's fighting in history; Adrian Goldsworthy equates the death toll at Cannae to "the massed slaughter of the British Army on the first day of the Somme offensive in 1916." Only about 15,000 Romans, most of whom were from the garrisons of the camps and had not taken part in the battle, escaped death. Following the defeat, Capua and several other Italian city-states defected from the Roman Republic to Carthage.

[Q]: Question: How many year does the person who appoints governors in India serve per term? Passage:In the Republic of India, a governor is the constitutional head of each of the twenty-eight states. The governor is appointed by the President of India for a term of five years, and holds office at the President's pleasure. The governor is de jure head of the state government; all its executive actions are taken in the governor's name. However, the governor must act on the advice of the popularly elected council of ministers, headed by the chief minister, which thus holds de facto executive authority at the state-level. The Constitution of India also empowers the governor to act upon his or her own discretion, such as the ability to appoint or dismiss a ministry, recommend President's rule, or reserve bills for the President's assent. Over the years, the exercise of these discretionary powers have given rise to conflict between the elected chief minister and the union government–appointed governor.
 Links: a. Government of India b. President of India c. Ministry (collective executive) d. Constitution of India
[A]: b
