QUES: All Freemasons begin their journey in the "craft" by being progressively initiated, passed and raised into the three degrees of Craft, or Blue Lodge Masonry. During these three rituals, the candidate is progressively taught the meanings of the Lodge symbols, and entrusted with grips, signs and words to signify to other Masons that he has been so initiated. The initiations are part allegory and part lecture, and revolve around the construction of the Temple of Solomon, and the artistry and death of his chief architect, Hiram Abiff. The degrees are those of Entered apprentice, Fellowcraft and Master Mason. While many different versions of these rituals exist, with at least two different lodge layouts and versions of the Hiram myth, each version is recognisable to any Freemason from any jurisdiction.

Who was the chief architect of the Temple of Solomon?
What is the answer?
ANS: Hiram Abiff

QUES: The primary source of rain in the Sahara is the equatorial low a continuous belt of low-pressure systems near the equator which bring the brief, short and irregular rainy season to the Sahel and the southern Sahara. The Sahara doesn't lack precipitation because of a lack of moisture, but due to the lack of a precipitation-generating mechanism. Rainfall in this giant desert has to overcome the physical and atmospheric barriers that normally prevent the production of precipitation. The harsh climate of the Sahara is characterized by extremely low, unreliable, highly erratic rainfall; extremely high sunshine duration values; high temperatures year-round; negligible rates of relative humidity, a significant diurnal temperature variation and extremely high levels of potential evaporation which are the highest recorded worldwide.
What is the primary source of rain in the Sahara?

ANS: low-pressure systems

In the run-up to the London 2012 Summer Olympic Games and London 2012 Summer Paralympic Games, Eton's purpose-built Dorney Lake, a permanent, eight-lane, 2,200 metre course (about 1.4 miles) in a 400-acre park, officially known throughout the Games as Eton Dorney, provided training facilities for Olympic and Paralympic competitors, and during the Games, hosted the Olympic and Paralympic Rowing competitions as well as the Olympic Canoe Sprint event, attracting over 400,000 visitors during the Games period (around 30,000 per day), and voted the best 2012 Olympic venue by spectators.

Ah, so.. unanswerable

Question: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (£1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.
Try to answer this question if possible: Where was Chopin's initial performance?
Answer: Stafford House
