The Comparsa is a development of African processions where groups of devotees follow a given saint or deity during a particular religious celebration". One of the most popular comparsas of Fiesta de Carnaval is the male group comparsa, usually composed of notable men from the community who dress up in outlandish costumes or cross-dress and dance to compete for money and prizes. Other popular activities include body painting and flour fighting. "On the last day of Carnival painters flood the street to paint each other. This simply means that a mixture of water paint and water or raw eggs is used to paint people on the streets, the goal being to paint as many people as you can".

Question: What's the name of the vehicle where the musicians play?

Here is a question about this article: Brasilia is known as a departing point for the practice of unpowered air sports, sports that may be practiced with hang gliding or paragliding wings. Practitioners of such sports reveal that, because of the city's dry weather, the city offers strong thermal winds and great "cloud-streets", which is also the name for a manoeuvre quite appreciated by practitioners. In 2003, Brasilia hosted the 14th Hang Gliding World Championship, one of the categories of free flying. In August 2005, the city hosted the 2nd stage of the Brazilian Hang Gliding Championship.
What is the answer to this question: What type of sports are popular in Brasilia?
****
So... unpowered air sports

The problem: Answer a question about this article:
In Islam, dogs are viewed as unclean because they are viewed as scavengers. In 2015 city councillor Hasan Kucuk of The Hague called for dog ownership to be made illegal in that city. Islamic activists in Lerida, Spain, lobbied for dogs to be kept out of Muslim neighborhoods, saying their presence violated Muslims' religious freedom. In Britain, police sniffer dogs are carefully used, and are not permitted to contact passengers, only their luggage. They are required to wear leather dog booties when searching mosques or Muslim homes.
When did it become illegal for a person to own a dog in The Hague?
****
The answer: 2015

Problem: Please answer a question about the following article about Printed circuit board:
At the glass transition temperature the resin in the composite softens and significantly increases thermal expansion; exceeding Tg then exerts mechanical overload on the board components - e.g. the joints and the vias. Below Tg the thermal expansion of the resin roughly matches copper and glass, above it gets significantly higher. As the reinforcement and copper confine the board along the plane, virtually all volume expansion projects to the thickness and stresses the plated-through holes. Repeated soldering or other exposition to higher temperatures can cause failure of the plating, especially with thicker boards; thick boards therefore require high Tg matrix.
When resin stays below Tg, its thermal expansion is similar to that of copper and what other material?
A: glass

Evidence of Han-era mechanical engineering comes largely from the choice observational writings of sometimes disinterested Confucian scholars. Professional artisan-engineers (jiang ) did not leave behind detailed records of their work. Han scholars, who often had little or no expertise in mechanical engineering, sometimes provided insufficient information on the various technologies they described. Nevertheless, some Han literary sources provide crucial information. For example, in 15 BC the philosopher Yang Xiong described the invention of the belt drive for a quilling machine, which was of great importance to early textile manufacturing. The inventions of the artisan-engineer Ding Huan () are mentioned in the Miscellaneous Notes on the Western Capital. Around 180 AD, Ding created a manually operated rotary fan used for air conditioning within palace buildings. Ding also used gimbals as pivotal supports for one of his incense burners and invented the world's first known zoetrope lamp.

Which engineer was responsible for first inventing the zoetrope lamp?
Answer: Ding Huan

As of the 201516 season, Premier League football has been played in 53 stadiums since the formation of the Premier League in 1992. The Hillsborough disaster in 1989 and the subsequent Taylor Report saw a recommendation that standing terraces should be abolished; as a result all stadiums in the Premier League are all-seater. Since the formation of the Premier League, football grounds in England have seen constant improvements to capacity and facilities, with some clubs moving to new-build stadiums. Nine stadiums that have seen Premier League football have now been demolished. The stadiums for the 201011 season show a large disparity in capacity: Old Trafford, the home of Manchester United has a capacity of 75,957 with Bloomfield Road, the home of Blackpool, having a capacity of 16,220. The combined total capacity of the Premier League in the 201011 season is 770,477 with an average capacity of 38,523.
In how many stadiums had Premier League been played as of the 2015-16 season?
53
