Article: Nuclear surety ensures the safety, security and effectiveness of nuclear operations. Because of their political and military importance, destructive power, and the potential consequences of an accident or unauthorized act, nuclear weapons and nuclear weapon systems require special consideration and protection against risks and threats inherent in their peacetime and wartime environments. The Air Force, in conjunction with other entities within the Departments of Defense or Energy, achieves a high standard of protection through a stringent nuclear surety program. This program applies to materiel, personnel, and procedures that contribute to the safety, security, and control of nuclear weapons, thus assuring no nuclear accidents, incidents, loss, or unauthorized or accidental use (a Broken Arrow incident). The Air Force continues to pursue safe, secure and effective nuclear weapons consistent with operational requirements. Adversaries, allies, and the American people must be highly confident of the Air Force's ability to secure nuclear weapons from accidents, theft, loss, and accidental or unauthorized use. This day-to-day commitment to precise and reliable nuclear operations is the cornerstone of the credibility of the NDO mission. Positive nuclear command, control, communications; effective nuclear weapons security; and robust combat support are essential to the overall NDO function.

Question: What ensures the safety of nuclear operations? 
Ans: Nuclear surety

The problem: Answer a question about this article:
Various owners leased it from royal landlords and the freehold was the subject of frenzied speculation during the 17th century. By then, the old village of Eye Cross had long since fallen into decay, and the area was mostly wasteland. Needing money, James I sold off part of the Crown freehold but retained part of the site on which he established a 4-acre (16,000 m2) mulberry garden for the production of silk. (This is at the northwest corner of today's palace.) Clement Walker in Anarchia Anglicana (1649) refers to "new-erected sodoms and spintries at the Mulberry Garden at S. James's"; this suggests it may have been a place of debauchery. Eventually, in the late 17th century, the freehold was inherited from the property tycoon Sir Hugh Audley by the great heiress Mary Davies.
Who sold off part of the Crown Freehold?
****
The answer: James I


Problem: Please answer a question about the following article about House music:
Early house music was generally dance-based music characterized by repetitive 4/4 beats, rhythms mainly provided by drum machines, off-beat hi-hat cymbals, and synthesized basslines. While house displayed several characteristics similar to disco music, it was more electronic and minimalistic, and the repetitive rhythm of house was more important than the song itself. House music in the 2010s, while keeping several of these core elements, notably the prominent kick drum on every beat, varies widely in style and influence, ranging from the soulful and atmospheric deep house to the more minimalistic microhouse. House music has also fused with several other genres creating fusion subgenres, such as euro house, tech house, electro house and jump house.
What are some subgenres of House music?
A: euro house, tech house, electro house and jump house


Question: Read this and answer the question

Apple's HyperCard scripting language provided Macintosh computer users with a means to design databases of slides, animation, video and sounds from LaserDiscs and then to create interfaces for users to play specific content from the disc through software called LaserStacks. User-created "stacks" were shared and were especially popular in education where teacher-generated stacks were used to access discs ranging from art collections to basic biological processes. Commercially available stacks were also popular with the Voyager company being possibly the most successful distributor.

Which of Apple's programming languages allowed users to ceatively manipulate LaserDiscs?
Answer: HyperCard


The British dealt with range measurement first, when it was realised that range was the key to producing a better fuse setting. This led to the Height/Range Finder (HRF), the first model being the Barr & Stroud UB2, a 2-metre optical coincident rangefinder mounted on a tripod. It measured the distance to the target and the elevation angle, which together gave the height of the aircraft. These were complex instruments and various other methods were also used. The HRF was soon joined by the Height/Fuse Indicator (HFI), this was marked with elevation angles and height lines overlaid with fuse length curves, using the height reported by the HRF operator, the necessary fuse length could be read off.
What was the first model of HRF (Height Range Finder) used by the British?
Barr & Stroud UB2
