Problem: The name Montana comes from the Spanish word Montaña, meaning "mountain", or more broadly, "mountainous country". Montaña del Norte was the name given by early Spanish explorers to the entire mountainous region of the west. The name Montana was added to a bill by the United States House Committee on Territories, which was chaired at the time by Rep. James Ashley of Ohio, for the territory that would become Idaho Territory. The name was successfully changed by Representatives Henry Wilson (Massachusetts) and Benjamin F. Harding (Oregon), who complained that Montana had "no meaning". When Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time Rep. Samuel Cox, also of Ohio, objected to the name. Cox complained that the name was a misnomer given that most of the territory was not mountainous and that a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but it was eventually decided that the Committee on Territories could name it whatever they wanted, so the original name of Montana was adopted.
What did the Spanish call this region?
The answer is the following: Montaña del Norte

Problem: 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.
A conformal coating can be applied by spraying the PCB or by doing what else to it?
The answer is the following: dipping

Problem: Meanwhile, Le Verrier by letter urged Berlin Observatory astronomer Johann Gottfried Galle to search with the observatory's refractor. Heinrich d'Arrest, a student at the observatory, suggested to Galle that they could compare a recently drawn chart of the sky in the region of Le Verrier's predicted location with the current sky to seek the displacement characteristic of a planet, as opposed to a fixed star. On the evening of 23 September 1846, the day Galle received the letter, he discovered Neptune within 1° of where Le Verrier had predicted it to be, about 12° from Adams' prediction. Challis later realised that he had observed the planet twice, on 4 and 12 August, but did not recognise it as a planet because he lacked an up-to-date star map and was distracted by his concurrent work on comet observations.
What was Challis looking for when he saw Neptune the first two times? 
The answer is the following: comet observations

Problem: Norfolk Island Hospital is the only medical centre on the island. Medicare and the Pharmaceutical Benefits Scheme do not cover Norfolk Island. All visitors to Norfolk Island, including Australians, are recommended to purchase travel insurance. Although the hospital can perform minor surgery, serious medical conditions are not permitted to be treated on the island and patients are flown back to mainland Australia. Air charter transport can cost in the order of A$30,000. For serious emergencies, medical evacuations are provided by the Royal Australian Air Force. The island has one ambulance staffed by St John Ambulance Australia volunteers.
Who staffs the one ambulance available on Norfolk Island?
The answer is the following:
St John Ambulance Australia volunteers
