Problem: BeiDou Navigation Satellite System:

The ranging signals are based on the CDMA principle and have complex structure typical of Galileo or modernized GPS. Similar to the other GNSS, there will be two levels of positioning service: open and restricted (military). The public service shall be available globally to general users. When all the currently planned GNSS systems are deployed, the users will benefit from the use of a total constellation of 75+ satellites, which will significantly improve all the aspects of positioning, especially availability of the signals in so-called urban canyons. The general designer of the COMPASS navigation system is Sun Jiadong, who is also the general designer of its predecessor, the original BeiDou navigation system.

Which signals are based on the ABCD principle?

A: unanswerable


Problem: The Royal Australian Navy is in the process of procuring two Canberra-class LHD's, the first of which was commissioned in November 2015, while the second is expected to enter service in 2016. The ships will be the largest in Australian naval history. Their primary roles are to embark, transport and deploy an embarked force and to carry out or support humanitarian assistance missions. The LHD is capable of launching multiple helicopters at one time while maintaining an amphibious capability of 1,000 troops and their supporting vehicles (tanks, armoured personnel carriers etc.). The Australian Defence Minister has publicly raised the possibility of procuring F-35B STOVL aircraft for the carrier, stating that it "has been on the table since day one and stating the LHD's are "STOVL capable".
Who is in the process of procuring two Canbera-class LHD's?

Answer: The Royal Australian Navy


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the AC and resulting magnetic field which drives it. Another way of saying this is that it has zero slip under usual operating conditions. Contrast this with an induction motor, which must slip to produce torque. One type of synchronous motor is like an induction motor except the rotor is excited by a DC field. Slip rings and brushes are used to conduct current to the rotor. The rotor poles connect to each other and move at the same speed hence the name synchronous motor. Another type, for low load torque, has flats ground onto a conventional squirrel-cage rotor to create discrete poles. Yet another, such as made by Hammond for its pre-World War II clocks, and in the older Hammond organs, has no rotor windings and discrete poles. It is not self-starting. The clock requires manual starting by a small knob on the back, while the older Hammond organs had an auxiliary starting motor connected by a spring-loaded manually operated switch.
Whithout rotor windings, how must a Hammond clock be started?
A: manually


Context and question: In addition to the principal cast, Alessandro Cremona was cast as Marco Sciarra, Stephanie Sigman was cast as Estrella, and Detlef Bothe was cast as a villain for scenes shot in Austria. In February 2015 over fifteen hundred extras were hired for the pre-title sequence set in Mexico, though they were duplicated in the film, giving the effect of around ten thousand extras.
Who was cast as Marco Sciarra?
Answer: Alessandro Cremona


Question: While he searched for enlightenment, Gautama combined the yoga practice of his teacher Kalama with what later became known as "the immeasurables".[dubious – discuss] Gautama thus invented a new kind of human, one without egotism.[dubious – discuss] What Thich Nhat Hanh calls the "Four Immeasurable Minds" of love, compassion, joy, and equanimity[full citation needed] are also known as brahmaviharas, divine abodes, or simply as four immeasurables.[web 5] Pema Chödrön calls them the "four limitless ones". Of the four, mettā or loving-kindness meditation is perhaps the best known.[web 5] The Four Immeasurables are taught as a form of meditation that cultivates "wholesome attitudes towards all sentient beings."[web 6][web 7]
Is there an answer to this question: Gautama combined the yoga practice of what teacher?

Answer: Kalama


Question: Beer ranges from less than 3% alcohol by volume (abv) to around 14% abv, though this strength can be increased to around 20% by re-pitching with champagne yeast, and to 55% abv by the freeze-distilling process. The alcohol content of beer varies by local practice or beer style. The pale lagers that most consumers are familiar with fall in the range of 4–6%, with a typical abv of 5%. The customary strength of British ales is quite low, with many session beers being around 4% abv. Some beers, such as table beer are of such low alcohol content (1%–4%) that they are served instead of soft drinks in some schools.
Is there an answer to this question: What is the typical alcohol content of a pale logger?

Answer:
5%
