The problem: Answer a question about this article:
The legions of the late Republic were, structurally, almost entirely heavy infantry. The legion's main sub-unit was called a cohort and consisted of approximately 480 infantrymen. The cohort was therefore a much larger unit than the earlier maniple sub-unit, and was divided into six centuries of 80 men each. Each century was separated further into 10 "tent groups" of 8 men each. The cavalry troops were used as scouts and dispatch riders rather than battlefield cavalry. Legions also contained a dedicated group of artillery crew of perhaps 60 men. Each legion was normally partnered with an approximately equal number of allied (non-Roman) troops.
Who would now be used as scouts instead of fighting alongside the army in the battlefield?
****
The answer: cavalry troops

The port on Montevideo Bay is one of the reasons the city was founded. It gives natural protection to ships, although two jetties now further protect the harbour entrance from waves. This natural port is competitive with the other great port of Rio de la Plata, Buenos Aires. The main engineering work on the port occurred between the years 1870 and 1930. These six decades saw the construction of the port's first wooden pier, several warehouses in La Aguada, the north and south Rambla, a river port, a new pier, the dredged river basin and the La Teja refinery. A major storm in 1923 necessitated repairs to many of the city's engineering works. Since the second half of the 20th century, physical changes have ceased, and since that time the area has degraded due to national economic stagnation.

What gives natural protection to ships in Montevideo?
Answer: The port on Montevideo Bay

Problem: Believing the northern approaches to the city too well defended, especially due to the presence of a large star fort and because Sevastopol was on the south side of the inlet from the sea that made the harbour, Sir John Burgoyne, the engineer advisor, recommended that the allies attack Sevastopol from the south. This was agreed by the joint commanders, Raglan and St Arnaud.:426 On 25 September the whole army marched southeast and encircled the city to the south. This let them set up a new supply center in a number of protected inlets on the south coast. The Russians retreated into the city.
Who was the engineer adviser?
The answer is the following: Sir John Burgoyne

Here is a question about this article: In the late 13th and early 14th centuries, a process took place primarily in Italy but partly also in the Empire that historians have termed a 'commercial revolution'. Among the innovations of the period were new forms of partnership and the issuing of insurance, both of which contributed to reducing the risk of commercial ventures; the bill of exchange and other forms of credit that circumvented the canonical laws for gentiles against usury, and eliminated the dangers of carrying bullion; and new forms of accounting, in particular double-entry bookkeeping, which allowed for better oversight and accuracy.
What is the answer to this question: What new form of accounting was created during the late 13th and early 14th centuries?
****
So...
double-entry bookkeeping
