Problem: Montevideo:

The first set of subsidiary forts were planned by the Portuguese at Montevideo in 1701 to establish a front line base to stop frequent insurrections by the Spaniards emanating from Buenos Aires. These fortifications were planned within the River Plate estuary at Colonia del Sacramento. However, this plan came to fruition only in November 1723, when Captain Manuel Henriques de Noronha reached the shores of Montevideo with soldiers, guns and colonists on his warship Nossa Senhora de Oliveara. They built a small square fortification. However, under siege from forces from Buenos Aires, the Portuguese withdrew from Montevideo Bay in January 1724, after signing an agreement with the Spaniards.

Where were the Spaniards emanating from?
---
A: Buenos Aires

Problem: Armenians:

From the 9th to 11th century, Armenian architecture underwent a revival under the patronage of the Bagratid Dynasty with a great deal of building done in the area of Lake Van, this included both traditional styles and new innovations. Ornately carved Armenian Khachkars were developed during this time. Many new cities and churches were built during this time, including a new capital at Lake Van and a new Cathedral on Akdamar Island to match. The Cathedral of Ani was also completed during this dynasty. It was during this time that the first major monasteries, such as Haghpat and Haritchavank were built. This period was ended by the Seljuk invasion.

What Armenian monasteries were built in the 11th century?
---
A: Haghpat and Haritchavank

Problem: Printed circuit board:

PCBs intended for extreme environments often have a conformal coating, which is applied by dipping or spraying after the components have been soldered. The coat prevents corrosion and leakage currents or shorting due to condensation. The earliest conformal coats were wax; modern conformal coats are usually dips of dilute solutions of silicone rubber, polyurethane, acrylic, or epoxy. Another technique for applying a conformal coating is for plastic to be sputtered onto the PCB in a vacuum chamber. The chief disadvantage of conformal coatings is that servicing of the board is rendered extremely difficult.

What action is made much more difficult for boards that have a conformal coating?
---
A: servicing

Problem: The Blitz:

The attacks were focused against western ports in March. These attacks produced some breaks in morale, with civil leaders fleeing the cities before the offensive reached its height. But the Luftwaffe's effort eased in the last 10 attacks as seven Kampfgruppen moved to Austria in preparation for the Balkans Campaign in Yugoslavia and Greece. The shortage of bombers caused the OKL to improvise. Some 50 Junkers Ju 87 Stuka dive-bombers and Jabos (fighter-bombers) were used, officially classed as Leichte Kampfflugzeuge ("light bombers") and sometimes called Leichte Kesselringe ("Light Kesselrings"). The defences failed to prevent widespread damage but on some occasions did prevent German bombers concentrating on their targets. On occasion, only one-third of German bombs hit their targets.

What was focused in March?
---
A:
western ports
